    Re: Refrigeration circuit in a bioethanol plant

    I suspect you would be referring to refrigeration of fermentation vessels. Yeast (which I suspect would be the organism used for the fermentation stage) works best at a certain temperature, which is...

    Re: Viton and Hydroflouric acid

    That is a bit of an understatement.

    Out of all the nasty stuff we had in the lab (inc. things like hydrogen cyanide), the hydrofluoric acid was kept on it's own, in a very small bottle, inside a...

    Re: Whats this new method for production?????

    KF is potassium fluoride, MgO is magnesium oxide.

    I don't think you'd be able to get hold of KF too easily, and to be quite honest, it's not the kind of thing to mess about with unless you know...

    Re: Whats this new method for production?????

    Do you have any details about the article, or references?

    At a guess it sounds like possibly anion or cation exchange resins (solids), but without more details it's hard to say.

    I think sodium, lithium and caesium might suggest otherwise (well, all of the alkali metals actually), but that aside, I have come accross similar problems before - with mineral oil.

    I had to...

  15. Re: More Pressure needed to make Bio Fuel Pumps Mandatory

    Just a note, octane rating has absolutely nothing to do with efficiency.

    It's literally a measure of the fuel's resistance to pre-ignition, relative to n-heptane and iso-octane (which I suspect is...

    No, smaller length won't give better gas production.

    The gas production is governed by how much current you are putting through.
