Two combined cryogenic processes cut sour natural-gas processing cost
Acid gases can be separated by cryogenic distillation and the combining of this process with other low-temperature processing steps such as LNG or LPG production and/or nitrogen rejection holds many advantages as are discussed in this article. The processing of sour natural gas is described by examining how processes such as acid gas removal, liquefaction, and nitrogen rejection could be integrated in a cost-effective fashion. The results of this work are two combined cryogenic processes which efficiently integrate acid gas removal with downstream low temperature processing. The advantages of this technology are that it produces no waste, uses only hydrocarbons and the process steams are noncorrosive. Technology in sour gas separation is evolving rapidly. The use of acid gas stream in the low-BTU turbine fuel can significantly reduce the horsepower and capital costs associated with the integration.
