Hi Ed,

Not sure what you mean by water in this context. Separation of kero from castor is a common problem once thought unsolvable until Klotz Castor came along. And even then, at low temps, the castor settles out. But in this case, no water involved.

Water is only an issue when making BioFuel or BioLube as water is introduced into the process. If that's what you mean, then your suggestion may have merit. But my take is that it would be better to get the water out in the first place. With Fuel, it just needs to be allowed to evaporate. With Lube it has to be forced out by heating.
