Re: [biofuel] methanol/methoxide vacuum concern
Thanks David. I did a quick search on the net and found one or two conversion charts which didnt have mws.

If youve looked at my hoto, http://www.hammaskeep.demon.co.uk/process.jpg my methoxide mixer is to the right, the grey tank. Now I'm concerned, as so far for my initial test batch I poured the methanol/methoxide straight in to the reactor (2 stage process). But I'm now wanting to use suction to deliver the methanol/methoxide. Will this pose a problem with boiling? Its having to lift approx 30 vua 15mm pipe amb temp 15 - 20oC Also I need some help with vacuum pressure. I see most measure by Hg I have a gauge which shows mws which goes to -10. Does anyone have figures and conversion for vacuum pressures. I need to know if my vac pump is capable of reclaiming methanol. I think it is, as its a corker of a unit, I just dont know what its measured capability is.
