Description

Used 30 MMSCFD CO2 removal plant for sale. The plant is designed to use multiple stage membrane process to remove 71% CO2 from inlet natural gas. After dehydration, the inlet gas is routed to the first membrane. The first separation removes about 40% of the incoming CO2 and delivers a high CO2 permeate off gas stream at a pressure of near 75 psia. This 96% quality permeate stream can be vented or can be re-compressed and delivered to a CO2 pipeline for commercial sales. The CO2 in the inlet gas stream is reduced from near 74% to near 60% in this first stage. The second stage of the membrane separation reduces the incoming CO2 from 60% to near 20%. The third stage of the membrane reduces the incoming CO2 from near 20% to approximately 6%. The fourth stage of the membrane reduces the incoming CO2 from near 6% to approximately 3%. The second, third and fourth stages of the membrane separation produce permeate streams at a pressure near 30 psia. All three streams are combined together along with a dehydrated side stream coming from well. After each stage of membrane CO2 separation, the treated stream exits the membrane as a two-phase fluid. Each membrane is configured with liquid separation on the treated gas stream. The fourth stage exit stream is refrigerated to condense even more liquid hydrocarbon. The liquid hydrocarbon streams from each stage of membranes are combined and routed to a NGL stabilizer where it is stabilized to meet a MAPCO "Y" grade specification. The resultant product will be stored in NGL storage vessels and trucked out to NGL markets.
