Surface Equipment Corporation manufactures well stream blow case units for its customers on an individual customized basis. A blow case is usually a pressure assist unit for the removal of larger volumes of liquids from near well head produced gas in a small package. Pressure from the gas stream is used to force fluid from the reservoir to reduce drain cycle times and improve flow through the separation section of the units. Units are usually mounted vertically in tandem on a skidded platform. Instrumentation is provided for removal of liquids and monitoring of gas stream and vessel liquid levels.
