ABSTRACT:
A closed loop process is shown for treating oil and saline contaminated particulate materials such as drilling cuttings such as are encountered in oil and gas well bore drilling operations. The process includes at least two washing stages and three solids separation stages. A process fluid tank utilizes an auger to remove deposited solids from the process fluid while hot gases being bubbled through the tank facilitate separation and skimming of oil and hydrocarbon components from the tank surface.
