[Biofuel] Greenhouse gases, Regulated Emissions, and Energy use in Transportation

To fully evaluate energy and emission impacts of advanced vehicle technologies and new transportation fuels, the fuel cycle from wells to wheels and the vehicle cycle through material recovery and vehicle disposal need to be considered. Sponsored by the U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy (EERE), Argonne has developed a fuel-cycle model called GREET (Greenhouse gases, Regulated Emissions, and Energy use in Transportation). It allows researchers and analysts to evaluate various vehicle and fuel combinations on a full fuel-cycle basis. GREET was developed as a multidimensional spreadsheet model in Microsoft Excel. This public domain model is available free of charge for anyone to use. The first version of GREET was released in 1996. Since then, Argonne has continued to update and expand the model. The most recent GREET version is GREET 1.6 beta version. For a given vehicle and fuel system, GREET separately calculates the following: * Consumption of total energy (energy in non-renewable and renewable sources), fossil fuels (petroleum, natural gas, and coal), and petroleum * Emissions of CO2-equivalent greenhouse gases - primarily carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) * Emissions of five criteria pollutants: volatile organic compounds (VOCs), carbon monoxide (CO), nitrogen oxide (NOx), particulate matter with size smaller than 10 micron (PM10), and sulfur oxides (SOx). GREET includes more than 30 fuel-cycle pathway groups. It also includes these vehicle technologies * Conventional spark- ignition engines * Direct-injection, spark- ignition engines * Direct injection, compression ignition engines * Grid-connected hybrid electric vehicles * Grid-independent hybrid electric vehicles * Battery-powered electric vehicles * Fuel-cell vehicles. To address technology improvements over time, GREET separates fuels and vehicle technologies into near- and long-term options. The latter are assumed to have improved energy and emission performance compared with the former. Uses of GREET Argonne has used GREET to evaluate various engine and fuel systems for DOE, other government agencies, and industry (see publications list). Other organizations have used GREET for their evaluation of advanced vehicle technologies and new transportation fuels. GREET users include government agencies, the auto industry, the energy industry, research institutes, universities, and public interest groups. GREET users are spread in North America, Europe, and Asia. ___ 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/

[Biofuel] BD as heating oil
Good day to all, I've been using a 30% biodiesel : 70% #2 heating oil blend in my oil burner for heat and hot water. When I spoke to the people who service my burner and they said: "Don't use that stuff in your oil.It will ruin your burner." I have a Beckett oil burner and so I called their technical department. (All of this 6 months after starting to use the blend and in the midst of the coldest weather we've had). The technician told me that there is a rubber seal in the pump and that it will get "eaten away" by biodiesel and the pump will leak oil out the bottom of the furnace creating a dangerous situation." I began to email various plumbing supply outlets and oil burner companies. I recieved an interesting reply from Joe Moody at Patriot-Supply.comPlainview (USA). "I am far from an expert on the Bio Diesel fuel. Here is what I know so far. Webster Fuel Pump Company has just come out with a pump that will work in this application. Below is a link to that pump and specifications. We are currently out of these pumps but we will have more next week. There seems to be a big demand for these pumps. .. We sell the pump for $73.50. I am going to start doing a bit more research because this is a growing product for us and we would like to develop our Bio Diesel product line further." http://www.websterfuelpumps.com/ln4756.pdf The pump "M34DM-3 Bio Pump" contains Viton seals and can pumps blends of BD from 5% - 100%. I don't know Joe and am not promoting Patriot Plumbing Supply or Webster Pumps for that matter. There has been some discussion of BD (and BioHeating Oil) on the list. Material incompatibility seems to persist, and if a rubber gasket stands in the way of using BD as heating oil, then maybe this is the solution. It was also encouraging to hear that "this is a growing product for us and we would like to develop our Bio Diesel product line further."

Re: [Biofuel] BD as heating oil
Not being an expert in pump service, what would be more economical in this situation, replacing the pump with a Viton-sealed unit, or replacing the seals in the existing pump for Viton seals? (Obviously, this would have to wait until the weather warmed up.) Will a B30 blend be that erosive to a rubber seal? I know that rubber+B100 spells trouble, but a blend should be that much less erosive, should it not?

[Biofuel] KOH Differences
To everyone that sent me information on testing the differences in KOH. As you recall I got a 50 # bag for $10 at a blue light special at my local chemical supplier. I did the titration against lab grade near absolute and found after 2 separate titration about a 6% degrade in quality. Using this figure I increased my batch KOH and made a batch - Perfect ! Thanks every one!

Re: [Biofuel] BD as heating oil
Andrew, For BD5, BD20, and even the BD30 blend that I've been using, replacing the seal w. viton would probably be fine, but for higher blends viscosity might be a problem that would require higher pressure from a pump designed to handle up to BD100. Imagine, for under $100 (US) just say no to HHO.

Re: [Biofuel] Bio-Diesel in Palestine
Elad, Sorry to be slow in responding to your other questions. We've got a 325 gallon batch system similar to the design you saw at JTF that burped a couple of times last week which created a 1,500 gallon bottleneck we've been busy overcoming. Problem was seals on two new pumps failing straight out of the box and a weak bulkhead fitting that couldn't take the pressure of a completely filled tank. Had to jostle the contents to other tanks to effect repairs, which throttled everything instantly. Good things came of it though. First one is a greater degree of appreciation for diked facilities. Most people greatly overlook the safety and sanity margin afforded by a little concrete applied as a containment barrier. As for the design on JTF, it's a little overkill unless you're producing flat out. We have a lite version that's recommended for those producing perhaps only one cycle daily or less.The design you saw is presently being engineered with slight alterations as a turn key plant to be produced in quantities of scale. That should bring costs down considerably in comparison to constructing ones and twos. When the drawing was published at JTF (pushing two years now?) it was done primarily to show those interested what is involved to properly (environmentally and economically efficient) prepare biodiesel. Most who get into biodiesel, even many engineers, are a wee tad clueless and soon find there to be far more in a cradle to grave system than what they may have originally thought. The primary reason that few specs were assigned to the drawing is that many prospective builders/owners will perhaps have a large degree of the equipment needed already on hand, helping to avoid capital costs. In dairy country, much of the system could be built out of discarded or dormant dairy equipment. As well, there are a lot of sharp tacks out there that could build a plant without the help of consultants, engineers and high-priced blueprints, if they only had a guideline to work from. So the design was left as a general layout. There were two other reasons it wasn't presented at an engineered level. The first is that if the viewer couldn't grasp what was occurring on the flow sheet, they probably ought to become considerably more familiar with the process and the handling of all co products before continuing. The other was that there are entire herds of sharpies out there looking to market other people's work for a profit without putting any effort or understanding into the process proper. We get numerous contacts each week demanding that we make engineered drawings available to them, quite literally for free. Don't have much patience for demanding people. On the other hand, we'll darned near give anything away for free to those who were raised with a dash less arrogance. That said, be aware that the process is lineal. The design you mention can be scaled up or down with essentially no changes. We have made some mods relative to mixing and pumping. We're opting out of mechanical stirring and electrical pumps/motors, not only to increase safety margins, but their increased cost at larger scales. Pneumatic is essentially explosion proof and brings such a system back under regulatory radar in that respect. Pneumatic is also more serviceable and components can be more universal in applications that require variable pump speeds. If you end up engineering this yourself, the suggestion would be to stay with a manual system, either literally or centrally operated. PLC automation is an unnecessary extravagance, in my not so always humble belief. As for production schedules? You could easily achieve four cycles in a twenty-four hour period. The system would need to include flash dryers at the finishing stage and depending upon the type of feedstock and degree of degradation you might have to either double the number of esterification tanks or increase the size. Another option, again depending upon your feedstock, would be to eliminate the esterification stage, and after recovering a sufficient volume of free fatty acids occassionally use the transesterification reactor for a batch esterification cycle. The option really all depends upon the value and quality of your feedstock, how much process heat you'll need in your plant (to which your FFAs can be directed as boiler fuel) and the per finished unit cost of one direction or the other. Perhaps if you could better indicate what some of your parameters are going to be, a target could be zeroed in on a little more readily and we could help you circumnavigate some avoidable pitfalls. That's a large part of what we're doing this for. Todd Swearingen Appal Energy Elad Orian wrote: Hello All, I was moved to see the quick reply I got from all of you around the world.
