[Biofuel] Methanol recovery;
Hey Tom et al; I think I might have a new solution for our woes re. re-use of methanol. Rather than trying to dry it for re-use in making BD we might be able to just use it for fuel. This local dude who is way into performance diesels comes into my place last night to talk about BD production and when I start talking about recovered methanol he suggests spraying it into the air intake on the diesel engine. Apparently he pioneered this idea years ago and now it is common among the tractor pull crowd. It can have high water content with no problem, in fact he says they sometimes intentionally add water to methanol when using this technique to avoid overfueling the engine and yet still getting the cooling effect that they need when they go for more power and EGT shoots up to 1500 deg or more. It sounds dead simple to add a spray nozzle to the air intake and use the recovered methanol for an occasional power boost. He says it can easily give a 25% power increase. Another plus - you know how they describe on the TDI club pages about how to take the intake manifold off and clean all the black crap out so the engine breathes again? Methanol spray does this for you without taking anything apart. Sweet! I am looking for the downside to this idea. Can anyone here think of a reason this might be a bad idea?

We can handle the cold here, unlike our previous place, 18 months ago. That old wreck of a house was just too rotten, the weather went straight through it, very miserable when it froze over, difficult to do anything except try to keep warm, or to get warm rather. This is the same kind of 100-year-old farmhouse, but it's not rotten. We finished most of what we had to do before the snows came, nearly all of it in fact, complicated things with fields and pastures and grains and chickens and so on. Looks good, so far.

Re: [Biofuel] Methanol Recovery? Amazing !!
For all the different races creeds right down to individual family structures the thought patterns and the associated thought denominators are infinite. Common sense is not. For Keith to take the time to respond to the mail lets me know that 1/ he is alive and well on the hill/mountain and 2/ is not discriminatory but has a site open to all. For a whole to work as one it needs to understand all the globally diverse denominators and thus the responses to address them. Who knows where Mike or Keith will finish up or the influences/legacies they leave behind. Twould appear that nothing is immortal not even the earth we tread under foot.

[Biofuel] Methanol Recovery?
Hello everyone, I am scaling up the size of my processing units to make about 300-400gallons of biodiesel a day. Right now I do not do any methanol recovery however at the larger scale it makes a lot of finical sense to get back the methanol. I have had a lot of trouble finding somewhat larger devices for recovering the methanol. I was wondering if anyone has experience in this field. The internet mentions methanol recovery but no sights really go into methanol recovery and biodiesl. Any help would be appreciated. am open to either homemade designs or ones that can be purchased. Any useful links or links to pictures would be great.

Very simple -- you can't boil off methanol when both biodiesel and glycerine are present without shifting the equilibrium backwards to some extent. You can recover methanol out of a mixture of methanol with biodiesel, or out of a mixture of methanol with glycerine, but NOT out of a mixture of all three. -K ___ Biofuel mailing list Biofuel@sustainablelists.org http://sustainablelists.org/mailman/listinfo/biofuel_sustainablelists.org Biofuel at Journey to Forever: http://journeytoforever.org/biofuel.html Search the combined Biofuel and Biofuels-biz list archives (50,000 messages): http://www.mail-archive.com/biofuel@sustainablelists.org/

I seem to keep seeing statements along these lines but they seem very contrary within themselves. This sounds like "I want to evaporate off the methanol but, I can't do it because I will undo my processing". That doesn't sound convenient at all. What is the trick to evaporating the methanol without reversing the process?

I wouldn't ask but I can't >find anything in the archives. There's quite a lot about it in the archives, and more at JtF. Most of the methanol excess ends up in the by-product layer, the rest in the biodiesel (proportions at JtF), and both can/should be reclaimed. Though it's worth reading this too: More about methanol http://journeytoforever.org/biodiesel_make.html#moremeth The methanol in the glyc by-product can be reclaimed as-is, but if you have a use or a market for the separated by-products then separate the glycerine-FFA-catalyst first, and then reclaim the methanol from the glycerine fraction. With the portion in the biodiesel, reclaim before washing. Most convenient would be to reclaim it all at once right at the end of the process before removing the by-product while it's still hot and near the boiling point of methanol, but that throws the reaction into reverse, undoing the work you've just done making the biodiesel. You can reclaim the methanol with a pot-still or equivalent, with either the biodiesel or the by-product. Some people use vacuum too. No need for such high temperatures. The methanol starts to evaporate well before boiling point, but it doesn't really work like that anyway. Roughly speaking, if you make a 50/50 mix of two liquids with different boiling points they don't each boil off at their respective boiling points, the boiling point of the mixture will be about halfway between the two. Then there are complicated things about volatility and so on, but the one with the lower boiling point (ie the methanol) boils off first, and as it boils off the boiling point of the mixture rises until (in theory) there's none left, at the boiling point of the other liquid. With the by-product, you won't get it much above 100 deg C before it starts frothing, you'll have got most of the methanol but not all of it. If you use flash-evaporators you'll get better recovery with less energy input, for both bd and by-product. I think the positive effects on washing of recovering the methanol from the biodiesel first have been discussed, sorry, I don't have the time to pin it down right now.

Re: [Biofuel] methanol recovery from fuel stock?
Thanks buck yes I did know about the methanol boiling point. But after the evaporation process there should only be liquid. But my point in this experiment was to find out if it would help the wash process and reduce the water contamination. I didn't care about the methanol recovery so much at this point. I usually do try to extract the methanol from the glycerin in 6 gal batches but it is very hard to get full recovery. It is very hard to get above 120 deg F this way. My plan at this point is to separate the glycerine/ffas. And recover the methanol from the crude glycerin. But the question still is there any reason that this process should not be used? Will it do funky things to the finished product? If I were to adopt this process I would not heat it so severely or fast -Original Message- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Buck Williams Sent: Friday, November 04, 2005 7:55 PM To: Biofuel@sustainablelists.org Subject: Re: [Biofuel] methanol recovery from fuel stock? do youu guyss knolw hte bioling point of methanol is 149 f. and i dont know what the boilling point of diesel is but itw way below the boiling point of water at 212,, buck >From: JJJN <[EMAIL PROTECTED]> >Reply-To: Biofuel@sustainablelists.org >To: Biofuel@sustainablelists.org >Subject: Re: [Biofuel] methanol recovery from fuel stock? >Date: Fri, 04 Nov 2005 19:31:32 -0800 > >Hi Derick, > >I too am curios about this, but isnt 275 deg F on the edge of the >envelope Bio?

[Biofuel] methanol recovery from fuel stock?
I have pondering this for some time but figured I should get some success with making fuel first. Since alcohol is added from time to time to storage tanks so it will mix with the water and thus the blended alcohol water mixes with the fuel. This being the said, I wondered if the wash could be shortened or less of a waste problem by distilling the methanol out of the finished product before washing. ÊI have just finished a 120 liter batch I pulled off 1 liter of fuel stock ¸ I put in a old pressure cooker with the steam vent replaced with a hose barb and connected it to my evaporator. Turned the flame on and heated to 275 deg F for 10 minutes or so. Let it cool a bit and pored it into a pet bottle added the wash water shook it hard it separated in just a few minutes. The other half was just put in a pet bottle and wash water was added and shook it hard although it is separating not even close to the same speed as the demethanoled batch.

Re: [Biofuel] methanol recovery

Reverse osmosis could remove the methanol from the glycerine. You just need to find a membrane with a housing that is resistant to methanol.

Do I need to bring the glycerine to a rolling boil or just bring up the heat sufficiently to get the methanol to evaporate (148.5F/65C) not necessarily boiling ?

Re: [Biofuel] methanol recovery/first batch results
before each go of it. Once you have your catalyst amount determined re-do
the titration to be sure you got it right the first time and use the "Better
Titration" method.
http://journeytoforever.org/biodiesel_make2.html#bettertitrate
I have found that a VERY good electronic PH meter and scale are invaluable.
They help eliminate those two areas of potential variants.
The other sore spot I found to be heat. The processing heat should be 55C
(130F), and not considerably lower. A good thermometer helps.
http://journeytoforever.org/biodiesel_make2.html#lye All about lye and the
next one too "How much lye" gives you the groundwork for either NaOH or KOH
as a catalyst per volume of mathanol.
I have not attempted the two stage method yet nor am I intending to until
the one stage has become perfectly clear and I am getting consistant
positive results. Everything in it's time.

John, I am a novice at this too so others should feel free to criticize my
remarks.
I would suggest you titrate. This is not so easy at this stage because any
free fatty acids in your fuel as you went into the base process are now
soap, that is they are neutralized with Na.To convert them back to free
fatty acids, I have taken say 10 ml of the product, and mixed it with
vinegar strong enough to drop the pH back down to say 3 or 4. This will
strip off the sodium. Separate this 10 ml of oil from the vinegar. Now you
can titrate as if it were any waste or new oil. I think you are correct in
assuming that you should have titrated in the first place. If you find
that the free fatty acid is above 1 g/l equivalent NaOH then you will need
to be careful when washing not to add much water to the first few washes.
Check out the University of Idaho process. They use 5.5% to start out with
and mix it up before the glycerin phase is separated off. Then settle for
as long as it takes to get clear. But that process assumes you have the
correct amount of NaOH or KOH added to your mix in the first place. Since
you did not titrate first, you may not have added enough NaOH to neutralize
the FFA's as well as catalyze the reaction. So the reaction may not have
gone to completion. If you think that that is a possibility, You could
always separate the glycerin, titrate as above, add 1/4 the original
methanol
and enough NaOH to both neutralize as well as catalyze. Then re-react. This
second product will probably not drop any glycerin unless there was a lot
of unreacted oil.
I would probably let this batch settle and make a new batch with proper
titration. You will learn from the new batch how to deal with the old.

Please respond
to biofuel
what kind of a methanol recovery rate can I expect once I start doing that?
I got the product of my first conversion this morning and it looks straw
yellow but a bit cloudy, should I let it sit to clarify or should I wash
it? will the cloudiness wash out? does that mean that my reaction is
incomplete? should I add more lye and methanol and reprocess? should I
have titrated in the first place?

You will need to do your meth recovery before you wash it as washing will remove the meth into the wash water where its harder to recover. >will the cloudiness wash out? that cloudiness is a number of things, soaps, some glycerol. If you aren't doing meth recovery then I would just let it settle for a day or so (longer if you can). It allows small quantities of glycerol to settle out and makes for easier washing. If you are recovering then run your recovery then let it set. >should I have titrated in the first place? You should follow the instructions for which every process you're using.

Kenneth, I can see a problem here if the process was single base and the feedstock was high in FFA. The addition of acid could convert the soap formed from the initial neutralisation back into FFA. Careful monitoring of the ammount of acid added might prevent this.

Re: [biofuel] methanol recovery before separation
Catching up on ancient email. If one continues mixing until the reaction is complete and I have not heard of any evidence that indicates separation is required for the reaction to complete and then introduces into the reactor enough acid to quench the sodium catalyst then I see no reason why you should not be able to recover the methanol before separation. In fact if you follow the "Fool proof method" then you do almost exactly this. You separate the glycerin, mix it with phosphoric acid and mix it back into your biodiesel. You've quenched the reaction right there and have everything mixed up.

Re: [biofuel] methanol recovery before separation
Maud, The design is very simple. It works and works well, but is very slow. Five gallons of input can be run through in between 2-3 hours. There's just not much surface area for the trickle to pass over - width wise that is - limiting recovery to but that one thin continual trickle of fluid. The model I saw was fired by oil candles. The owner had taken three empty tuna fish cans, pushed the top inward and down to create a ledge similar to what a burning cigarette could be placed on when used as a homemade ash tray. A hole was punched through the ledge, a crude fiber wick pushed through it and the can filled with vegetable oil. We were discussing ways to improve the volume/time ratio. The first improvement would be to create better egress for the alcohol vapor all along the length of the evaporator, rather than only through the manifold at the top. That would literaly be a work of plumbing art and largely out of reach of the abilities of all but a handful of shadetreers. About the only other way to increase the output is to increase the number of tubes, each one being an individual evaporator which would then require it's own heat source as well as needle valves, etc. The easiest way that we can think of to improve the design and improve output without creating a Frahnkensteen monstor is to scrap it in all but principle and move the rivulet concept over to a flat plate evaporator. We've had some minor setbacks with flat plates adopting their own random drain patterns, quickly losing partial use of the full width of the plate. If the rivulet concept were included by milling small channels from top to bottom of the plate and spaced every few milimeters apart, there would be a stable "sheeting" of fluid over a broad surface area. In fact, the milled channels would increase the surface area that the fluid is in contact with in comparison to a purely flat plate evaporator. 'Course redesign would require an increase in symetrically distributed heat, probably meaning a water jacket beneath the plate, along with a considerably enlarged version of the condensor - not necessarily any more space consumed but an increased number of condensor tubes. The design would probably end up looking something akin to two shoe boxes butted up to each other in a "T" fashion. Long story short? There's probably not much need to get too carried away with the simple design. I believe it was intended more as a test/proving unit. There are still some thoughts of converting it to a home unit if the output can be easily improved. Then there's always the issue of the open flame heat source - not a problem with someone capable and cautious enough to create a vapor tight system. Not so sure that everyone falls into those categories of abilities though.

Chris, > What I am unsure of, and would like some advice > on is what is a good way to do methanol recovery? > and what is the preferred method of transfer from > container to container? A thin film evaporator coupled to a condensor is the best method of recovery. A rough verbal description can be found at http://groups.yahoo.com/group/biofuel/message/30463 Something like this could easily be scaled up and modularized to match volumes of production. The heat source can be anything you choose. But the idea of a thin drip down an enclosed and heated tube is probably as inexpensive and simple as you're going to get. Off the shelf stuff. Better than a pot still. Preferential methods to move alcohol would be gravity and positive displacement using air pressure. Magnetic pump with a TEFC (totally enclosed fan cooled) motor at minimum would be my next choice. Method of agitation is your choice. Prop agitation is brainless. Use a TEFC motor and make sure your motor base is solid as a rock. Pump agitation is equally as mindless. A magnetic drive pump would ensure that you'd have no seal leaks. Again, make sure the pump motor is a TEFC enclosure. Plastic containers can be heated with suspended heat exchangers of whatever preference. You'll not want to go beyond 120*F and preferably only use tanks rated at 1.9 specific gravity. Higher temps and thinner tanks will warp sooner. Insulate heavily.

Re: [biofuel] methanol recovery before separation
Maud, Condensers are easy enough to fabricate. Your trick is probably going to be figuring out what to use as an evaporator. Pot stills are a large headache due to the fact that they start to fry the liquid before the alcohol has evaporated. The thinner the layer of fluid the better, as there's not as much liquid for the alcohol to move through before it escapes as vapor. One of the simpler "thin film evaporators" that I've seen is a 3 foot piece of 1" copper tubing set at a 15 degree angle with two or three tea lights set underneath at six inch intervals. A small resevoir with a drip valve is plumbed in near the top. At the very top of the 1" tube is a "T" with four 1/2" tubes, 3' in length, branching off from it and angling downward. All four tie in at the bottom to a horizontal tube 1/2" in diameter, which is capped on one end and runs into a container on the other end.. The volume of the 4 tubes equals the volume of the 1 inch "evaporator" tube, so they can match the volume of whatever methanol evaporates in the 1" tube. The surface area of the 4 condensor tubes is double that of the 1" tube, so the heat will dissipate semi-quickly. If you can set the condensor tubes in a cold water bath there will be less chance that the evaporator will produce more vapor than the condensor can handle. The primary control over that is the rate of the drip from the resevoir. You'll know if the evaporator/condensor is "tuned" properly by the final volumes in each receiving container. A three foot run and a slow drip should be sufficient to evaporate all the methanol out of the biodiesel without elevating it's temp beyond ~160*F. You'll want to make sure that both the container that receives the recovered methanol and the container that receives the biodiesel (at the bottom of the evaporator tube) are vapor tight and each has a vent hose running outside. The vent is in case more vapor is produced than the condensor can handle. DO NOT simply seal the methanol container, as any methanol vapor that the condensor cannot handle (due to too fast a drip from the resevoir and/or too much heat to the evaporator) can back down through the evaporator and evacuate through the bottom. The vent hose on the container that receives the biodiesel is a precaution for an overheated or over-fed evaporator.

Re: [biofuel] methanol recovery before separation
Thanks, Todd, for going to the trouble of running that test. Can I run my own tests like the one you described if I can figure out how to make a condenser? Although I'm currently at the small batch (two liter-sized) processing level, I would like to develop and practice using a small condenser before I "graduate" to a larger scale. There is a lot of distilling information on the web that describes how to build a condenser on large scale. If it's possible to scale one down, are there any guidelines for sizing one that would be appropriate at the five-gallon level?

[biofuel] methanol recovery for beginners
Howdy y'all, I've been lurking about on this list and have a couple questions. I am forming a biodiesel co-op at my university (Appalachian State, NC) and this spring semester I plan to build a processor. I've made several 1L batches using Alex's 2-stage method. They seemed to turn out well. I've been working with a chemistry professor and will be able to continue working with him. I've studied biodiesel for a couple years now, but it seems that a lot of the info I know n processor's is a bit out dated now (fryer to the fuel tank era). I see that we need to be using closed processors and that methanol recovery is essential. I'm interested in building a processor to make about 80-100 gal a week off of wvo from the school. Last semester I welded a stand to hold a 100 gal hdpe container that could be covered to use as a processor. I understand that I will need a container to mix methoxide in, and a container to bubble wash and settle the biodiesel. What I am unsure of, and would like some advice on is what is a good way to do methanol recovery? and what is the preferred method of transfer from container to container? I am looking for salvaged or inexpensive materials, and a not too complex system. I do however have the help of several technology professors in my dept. What should I look for in a transfer pump?

Re: [biofuel] methanol recovery before separation
Maud, > is the amount of methanol remaining in the methyl ester > considered negligible? Is it possible to determine what percentage > remains in the methyl ester and what percentage in the glycerol? Maud Just for grins and giggles and to answer part of your question, a 100 milileter sample of un-washed biodiesel was run through an evaporator. (Not much of an "average sampling.") 100 milileters in and 97 milileters out. That would equate to an ~3% volume of alcohol residing in the fuel layer prior to alcohol recovery, or ~31 milileters of alcohol for every liter of biodiesel. That's ~15% of the original volume of alcohol. Not exactly insignificant. But then common sense never dictated that it would be. One qualifier. The unwashed fuel used to scratch out this number was from an aggregate vessel that is filled with fuel from multiple reactions, both straight base, acid/base, high volumes of alcohol per liter (250 ml) and standard volumes (200 ml). Still, I would assess 2%-3% as a conservatively safe value, at least until more refined numbers pop up.

Re: [biofuel] methanol recovery before separation
Hi again Todd
As far as the wash-water's concerned, water hyacinths quite happily
eat the first-wash water, methanol and all, clean it up nicely. Well,
actually it's a mix of water hyacinths and two types of duckweed,
about both of which there's much good information to be found at JtF:
http://journeytoforever.org/edu_pond.html#duckweed
http://journeytoforever.org/edu_pond.html#waterhyacinth
The washwater is innocuous enough, apart from the methanol - no heavy
metals or toxins, for instance, so the plants themselves remain
usable. Both make excellent compost, and that's a satisfactory
solution - not as satisfactory as reusing the excess methanol, but
you are recycling it well. Aslo the plants break the stuff down,
they're not full of methanol and lye, and still make good livestock
feed.
Best
Keith

Hi Todd
Yet that's what Dale Scroggins does, apparently with good results.
The touchless processor
http://journeytoforever.org/biodiesel_processor.html#touchfree
http://home.swbell.net/scrof/Biod_Proc.html
Michael Allen and Gumpon Prateepchaikul's set-up at Prince of Songkla
University in Thailand also reclaims the methanol at the end of the
processing stage, though differently, and with high efficiency and a
high-quality product (they test it).
I wonder if this isn't somewhat theoretical, as with the idea that
using acid in the wash will definitely backsplit biodiesel to FFAs
and must definitely be avoided. If properly done - which of course
shouldn't be merely so solve an emulsion problem (improve the
process!) - it has the advantage of thoroughly neutralizing the
catalyst, at the cost of traces of FFA which remain well within the
standard specs.
So here the same perhaps applies, as you indicate - a well-controlled
process with the right amount of catalyst and the right amount of
everything else too.
Needs and economics will differ from case to case, and I think
methanol recovery should be an option at each of the three possible
stages it can be done - straight after processing, using the existing
heat (to start with), recovering excess methanol from both the ester
and the by-product; recovering the excess methanol from the
by-product cocktail (that is most of it), which leaves the balance to
be accounted for (in the first wash water); recovering the excess
methanol from the glycerine itself after separating the by-product
components (which still leaves the balance in the first wash water).

Re: [biofuel] methanol recovery before separation
Maud,
I wouldn't consider the MeOH content in the biodiesel to be negligible. Not
at all.
Unfortunately, many others consider it so.
Simplest method to determine the volume of MeOH that resides in the
biodiesel and glycerol, as well as the volume that was consumed in reaction,
is to measure the volumes of alcohol laden biodiesel and glycerol, evaporate
the MeOH and then measure the remaining volumes of each.
The easiest way, IMNSHO, to determine if the MeOH volume in the biodiesel
fraction is negligible is to stick one's nose over a container and huff it.
(Not advised, but the point being made should be easy enough to decipher.)
Without removing the alcohol you've got a fluid that has a flashpoint
essentially the same as methanol, rather than the rather safe flashpoint of
biodiesel.
To test that theory, take a piece of cotton wick, anchor it in a 6 ounce
metal tomato paste can as if you're going to make a candle. Fill the can
with MeOH laden biodiesel. Light the wick as if the can were an oil candle.
Sit back and watch. Everything goes fine for a bit, that is until the fuel
heats up to the boiling point of alcohol. Then you have a runaway alcohol
torch.
That's the same alochol that would "normally" get washed down someone's
drain or flushed out into the back forty. The same stuff that a lot of
people consider "insignificant."
We haven't yet taken any time to quantify the average volume of MeOH that
remains in the biodiesel. But it is a safe bet that the ratio is consistent
between the biodiesel and glycerol fractions no matter how much alcohol is
originally used. The more alcohol used in the reaction, the more alcohol
will remain in the biodiesel and end up in the wastewater stream if
evaporation is not conducted prior.
Most people have probably noticed that MeOH and biodiesel are completely
miscible in each other in any volume.
If a person is worried about the energy inputs required to recover the
alcohol from the biodiesel, then they should be looking at insulation, heat
recovery and renewable fuels for the energy inputs.

Re: [biofuel] methanol recovery before separation
Lagonisa,
> The problem is
> that I have also read that due to the reversibility of the reaction,
The reaction is not exactly reversible. "Reversability" would require the
three glycerides and the glycerol recombining. That doesn't happen. Once the
glycerol is cleaved it is out of the picture.
You're suggesting MeOH recovery at the point where the reaction is complete
and the glycerol has yet to settle out. However, that's not altogether
adisable due to the continual mixing of excess catalyst with the methyl
ester.
If you reduce the volume of alcohol via evaporation at this point there
would be a propensity for some of the ester to fracture ("back crack") into
FFAs and then convert to soap. Mind you that "back cracking" can only occur
up to the point that all the catalyst is consumed in soap making.
If you can monitor the reaction and insure that the balance of catalyst is
infintesimally small beyond what is required to guarantee 100% completion,
erego yielding but a small and controlled amount of extra soap production,
then there might be some merit in extracting the alcohol prior to the
glycerin cocktail settling.
Otherwise? Probably none.

Re: [biofuel] methanol recovery before separation
Hello I'm a chemical engineering student working on a biodiesel production facility design project with my senior design group at NCSU. We are only in the initial stages and do not have a lot of kinetic data yet, but I would think that removing methanol would certainly be detrimental to your yield. I do not know if the resulting equilibrium shift towards reactants would be more than you were willing to give up or not, but something tells me it would certainly be noticeable based on the fact that most recipes suggest using a large excess of alcohol to push equilibrium towards the products (biodiesel and glycerin). lagonisa <[EMAIL PROTECTED]> wrote: Hello to all: I have read some contributions to this group about methanol recovery and the different options.

>When recovering the methanol, do you heat the whole batch after it >settles, or heat each part sepparately (biodiesel and glycerine)? > >Brent Sorry Brent, you didn't get a response to this: Different schools of thought on this. Some people just heat the whole thing up a bit more after the process and recover the methanol there and then, which has some advantages - it doesn't take much extra heat, for instance, compared with heating all or part up again from room temperature. Here's one such: The touchless processor http://journeytoforever.org/biodiesel_processor.html#touchfree Others say the disadvantage of this is that removing the methanol makes the glycerine by-product much more difficult to process. The by-product is actually a mixture glycerine, excess methanol, soaps and catalyst, and it can be separated - the methanol content makes it easier to work with. Here the methanol will end up in the separated glycerine, and can then be recovered. See: Separating glycerine/FFAs http://journeytoforever.org/biodiesel_glycsep.html Others again say it's not worth trying to recover the excess methanol from the biodiesel as most of it collects in the "glycerine" layer anyway, so just heat the by-product. If you do want to recover the methanol content from the biodiesel, you have to do it before washing, which will remove all the methanol. There's quite a lot about this in the archives. Here are a few previous messages, these mostly on possible water content of recovered methanol: >I've used and re-used about thirty gallons of methanol so far using >my hot pink vacuum still. At first I was worried about recovering >water at the end of a run, so watched the condensate closely for any >sign of cloudiness. I've never seen any.

There are some further options too. One system constantly condenses off methanol vapours and recycles the condensate back into bottom of the mixing tank, then recovers all the excess at the end, seems very efficient. But I don't think that set-up is doing glycerine-FFA separation of the by-product. On the other hand, if it's good oil you're using with low titration results the by-product will probably stay liquid anyway and might be easy to separate even without the excess methanol.

Re: [biofuel] Methanol recovery ???
Martin R. asks: >How do most of you , that recover there methanol or ethanol do it ??? >If you use a vacuum pump, where do you get one , and how do you set it up >how much can be recovered from the glycerine ,or can one recover the Methanol >from the entire BD batch , after the BD has been formed ??? I make 22 liter batches using a mixture of about 25% methanol and 75% ethanol. All the methanol gets consumed, and some of the ethanol. Since I do a glycerine wash with added water (15% of oil), one batch gives a glycerine layer containing about 2.2 liters of glycerine, 3.3 liters of water, and 4 liters ethanol. I only bother to distill the glycerine layer -- no vacuum, just a fractionating column with reflux. The ethanol comes over with water, of course, about 90% cuz my still is not real efficient. I get about 2.5 liters of the excess ethanol back, which is worth about $3.30 counting my freight costs. My methanol is only $3.00 a gallon, and I probly wouldn't bother recovering it, but it would work even better, since it would come over anhydrous. Yahoo!
