ABSTRACT:
A method of separating oil in water and other evaporable liquids from drilling mud, bleaching earth, sludge from oil tanks, oil shale or the like, the mud being evaporated at a lower temperature than with conventional evaporation due to the fact that the capillary forces binding the separate fractions in the pores of the mud are destroyed in a friction evaporator.
