Abstract
Rich natural gas is first compressed, and then cooled by a series of heat exchangers and an ambient air cooler. The cooled mixture of natural gas, natural gas liquid (NGL), and water is first separated in a high-pressure three-phase separator. NGL flows through a depressurization valve and NGL is separated from gas in a second separator for storage and transport such as in a conventional propane tank. A resulting lean natural gas is suitably conditioned for internal combustion, compressed natural gas processing, or liquid fuel processing.
