I am also looking into supersonic extraction of oil and cost effective methods of seperation at a large industiral scale. Ill keep you updated on my progress!
As a student, you may have access to a supercritical CO2 extraction machine. I sure would be interesting in finding out if that process works on wet algae. It should, and should be relatively low cost except for the capital expenses. If you can do it, I think that would be worth a PhD!
Very interesting. They use supercritical water rather than supercritical CO2, but it does show the promise of that general technology. Thank you.pochatoux wrote:DR Johansen wrote: As a student, you may have access to a supercritical CO2 extraction machine.

This is what they do in switzerland, the process is called SunCHem
...
At a lab scale, it appears to be cost efficient
