Abstract:
1. A flushable device for collecting gas and liquid from a well comprising: an inner vessel having a sidewall, an upper end and a lower end; a gas/liquid separator receiving said lower end of said inner vessel, said gas/liquid separator having an inlet line for admitting a combined stream into said gas/liquid separator; a liquid line passing through said sidewall of said inner vessel and down through said inner vessel into said gas/liquid separator, said liquid line forming a stinger that extends below said inlet line of said gas/liquid separator so that liquid separated from said combined stream will flow up said liquid line, said liquid line having an exit end; a liquid line motor valve in said liquid line; a gas line and gas vent extending from said upper end of said inner vessel, said gas line in communication with a gas collection system for conveying gas from said upper end of said inner vessel to said gas collection system; a gas line motor valve in said gas line; a top float in said inner vessel for activating said gas line motor valve; a bottom float in said inner vessel for activating said liquid line motor valve; a bypass line communicating said liquid line and said inlet line; a bypass valve located on said bypass line for selective closing of said bypass line; a backflow passageway in communication with said inlet line; wherein said bypass valve is selectively opened to permit backflow from the well to pass through said inlet line, said bypass line and said liquid line for flushing said gas/liquid separator.
