National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Upgrading Natural Gas Via Membrane Separation Processes.

DE2004834349

Publication Date	2000
Personal Author	Stern, S. A.; Rice, P. A.; Hao, J.
Page Count	56
Abstract	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.
