Abstract
Methods and means for economically compressing low volume, low pressure natural gas at the wellhead are provided. The means include an electrically operated, self starting compressor responsive to a low pressure inlet shut-off switch and a high pressure discharge shut-off switch. The means may also include a scrubber for separating liquid and condensate from the gas and means for automatically transporting such to a remote liquid storage tank. The compressor itself is an air compressor modified by the provision of natural gas crankcase purging and venting, suction port oil injection, and increase lubrication capacity.
