Abstract
A cavitation mixing apparatus is provided for performing separations from solid material using subcritical liquid CO2. A cavitation inducing device inside a cavitation mixing vessel is held in place with a cavitation mixer mount comprising at least one fluid channel for equalizing gaseous pressure of CO2 around the cavitation inducing device. Also described is method of separating oils from a crude plant oil mixture by injecting crude plant oil into a pressurized mixing vessel comprising liquid carbon dioxide and mixing the crude oil with the liquid carbon dioxide under pressure using powered induced cavitation, the cavitation mixing vessel comprising an encapsulated cavitation inducing device.
