Patent Number: 6,168,054

Title: Oil recovery system and apparatus

Abstract: A self-contained oil recovery system is mounted on a portable trailer. The oil recovery system includes an oil recovery tank, an air driven motor for transferring oil from a source to the oil recovery tank after the initial blow down of the oil source into the oil recovery tank, and a hydraulic driven discharge pump for transferring oil from the oil recovery tank to a well site facility. The oil recovery system is capable of transferring oil from the oil source into the oil recovery tank and at the same time transferring oil out of the oil recovery tank to the well site facility, inasmuch as the oil recovery tank is at atmospheric pressure. The air driven is operated by an air motor supplied with air from an air pressure tank maintained under pressure by an air compressure. The air compressor and the hydraulically driven discharge pump are operated by hydraulic motors. The hydraulic motors are operated as part of a hydraulic system including a hydraulic fluid reservoir and hydraulic controls and pumps. The hydraulic pump is driven by a self-contained motive power unit such as a diesel engine. In addition, the portable trailer is provided with hydraulic jacks for stabilizing the trailer mounted self-contained oil recovery system.
