Abstract: A vacuum tank is used to suck slop over 100 feet from a basin attached to the well head of an oil well. A vacuum is initiated in a vacuum tank by a vacuum pump and maintained when liquid flows into the vacuum tank by pumping liquid from the vacuum tank into a holding tank. The liquid from the holding tank is transferred to a truck tank by which it is carried to a place of disposal. The vacuum pump and liquid pump attached to the vacuum tank are powered by a diesel engine through a hydraulic power transmission system. The diesel engine is remotely controlled from the well-head area by a remote control which operates a starting relay at the diesel engine and also which regulates the speed between idle and operating speeds. The remote unit also has a light which indicates if the diesel engine is running.

Abstract: Spills from an oil well are caught in a basin surrounding the oil well casing. The basin is drained from the bottom through a conduit connected to a tank. A vacuum is applied to the tank by a suction pump. The control for starting and stopping the suction pump is by a control which is located above the basin. The control is manually operated by a man who works on a grating above the basin and may see into the basin.
