Upgrading Natural Gas Via Membrane Separation Processes.

[摘要] The objective of the present study is to assess the potential usefulness of membrane separation processes for removing CO(sub 2) and H(sub 2)S from low-quality natural gas containing substantial amounts of both these 'acid' gases, e.g., up to 40 mole-% CO(sub 2) and 10 mole-% H(sub 2)S. The membrane processes must be capable of upgrading the crude natural gas to pipeline specifications ((le) 2 mole-% CO(sub 2), (le) 4 ppm H(sub 2)S). Moreover, these processes must also be economically competitive with the conventional separation techniques, such as gas absorption, utilized for this purpose by the gas industry.
