Abstract
Rich natural gas is first compressed, then ambient air cooled and separated into lean natural gas, NGL and water. Hydrate formation during decompression of the lean gas is precluded by either heating the lean natural gas or mixing the lean natural gas with methanol or other additive before depressurization. Similarly, hydrate formation in the NGL is also precluded by either heating the NGL or mixing the NGL with methanol or other additive before depressurization. The NGL is conditioned for storage and transport in common propane tanks by a stabilizer or two-phase separator. The lean natural gas can be used for internal combustion, liquefied natural gas, compressed natural gas or liquid fuel processing.
