How about using a press?? Anyone with experience using a press?
Water is a chemical. CO2
is a chemical. Methanol is a chemical. Just how anti-chemical are you? If you could boil it out with water, would that be ok? How bout converting it internally into diesel with methanol which might be easily extracted. Would that be ok? If you extracted it with supercritical CO2
and then fully recycled the CO2
, is that ok?
The problem generally is getting the oil through a very tough cell wall that doesn't want to allow it through. If you disrupt the cell wall and release the grease, then centrifuging would probably be a simple way of separating it from the water that would also be released.
is a VERY good solvent. It will dissolve the lipids within the cells and allow them to pass thru the wall. Releasing the pressure just slightly converts the CO2
into a gas which immediately expresses the oil that had been dissolved. I suspect that the capital cost of a SC CO2
unit would be about the same as a high end centrifuge, which might not work anyway.
As you can tell, I think SC CO2
should be tried out.
