ABSTRACT:
This disclosure relates to a processor comprising means for mixing a process material with a process liquid (such as water) and forming an emulsion or slurry. Means is provided for pressuring and heating the slurry, and the slurry is then fed to means for quickly reducing the pressure to a relatively low value and further increasing the temperature. The rapid drop in pressure and increase in temperature causes volatile components of the slurry to convert to a gas and separate from the remainder of the slurry which is removed from the processor in the form of solids. The gas is fed to one or more condensers which separate the gas into useful liquids such as various grades of oil.
