The report evaluated the ability of Dehydro-Tech Corporation's (DTC) Carver-Greenfield Process to separate oil contaminated waste drilling muds to their constituent solids, oil and water fractions. The Carver-Greenfield Process (C-G) was developed by DTC in the late 1950's and is licensed in over 80 plants worldwide. The technology is designed to separate solid-liquid mixtures into three product streams: a clean, dry solid; a water product substantially free of solids and organics; and a concentrated mixture of extracted organics. A mobile pilot plant was used for the demonstration. The C-G Process demonstration was conducted at EPA's Edison, New Jersey facility in August, 1991. Waste drilling muds from the PAB Oil and Chemical Services, Inc. (PAB Oil) site in Vermilion Parish, Louisiana were processed in the demonstration. PAB Oil, which ceased operation in 1983, operated three oil drilling mud separation pits from which the waste material used in the demonstration was collected.
