Abstract

Three methods of isolating No. 2 diesel oil from a bentonite-based drilling fluid were evaluated: soxhlet extraction, ultrasonic extraction, and retort distillation. The efficiency of each method was demonstrated by either gas chromatographic analysis or by a determination of the weight or volume of the residue recovered. Of the methods evaluated, only retort distillation demonstrated recoveries greater than 90%.
