Book excerpt: A significant fraction of U.S. natural gas reserves are subquality due to the presence of acid gases and nitrogen; 13% of existing reserves (19 trillion cubic feed) may be contaminated with hydrogen sulfide. For natural gas to be useful as fuel and feedstock, this hydrogen sulfide has to be removed to the pipeline specification of 4 ppm. The technology used to achieve these specifications has been amine, or similar chemical or physical solvent, absorption. Although mature and widely used in the gas industry, absorption processes are capital and energy-intensive and require constant supervision for proper operation. This makes these processes unsuitable for treating gas at low throughput, in remote locations, or with a high concentration of acid gases. The U.S. Department of Energy, recognizes that exploitation of smaller, more sub-quality resources will be necessary to meet demand as the large gas fields in the U.S. are depleted. In response to this need, Membrane Technology and Research, Inc. (MTR) has developed membranes and a membrane process for removing hydrogen sulfide from natural gas. During this project, high-performance polymeric thin-film composite membranes were brought from the research stage to field testing. The membranes have hydrogen sulfide/methane selectivities in the range 35 to 60, depending on the feed conditions, and have been scaled up to commercial-scale production. A large number of spiral-wound modules were manufactured, tested and optimized during this project, which culminated in a field test at a Shell facility in East Texas. The short field test showed that membrane module performance on an actual natural gas stream was close to that observed in the laboratory tests with cleaner streams. An extensive technical and economic analysis was performed to determine the best applications for the membrane process. Two areas were identified: the low-flow-rate, high-hydrogen-sulfide-content region and the high-flow-rate, high-hydrogen-sulfide-content region. In both regions the MTR membrane process will be combined with another process to provide the necessary hydrogen sulfide removal from the natural gas. In the first region the membrane process will be combined with the SulfaTreat fixed-bed absorption process, and in the second region the membrane process will be combined with a conventional absorption process. Economic analyses indicate that these hybrid processes provide 20-40% cost savings over stand-alone absorption technologies.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose of this Task 2 Report is to present conceptual designs developed to treat a large portion of proven domestic natural gas reserves which are low quality. The conceptual designs separate hydrogen sulfide and large amounts of carbon dioxide (>20%) from methane, convert hydrogen sulfide to elemental sulfur, produce a substantial portion of the carbon dioxide as EOR or food grade CO[sub 2], and vent residual CO[sub 2] virtually free of contaminating sulfur containing compounds. A secondary purpose of this Task 2 Report is to review existing gas treatment technology and identify existing commercial technologies currently used to treat large volumes of low quality natural gas with high acid content. Section II of this report defines low quality gas and describes the motivation for seeking technology to develop low quality gas reserves. The target low quality gas to be treated with the proposed technology is identified, and barriers to the production of this gas are reviewed. Section III provides a description of the Controlled Freeze Zone (CFG)-CNG technologies, their features, and perceived advantages. The three conceptual process designs prepared under Task 2 are presented in Section IV along with the design basis and process economics. Section V presents an overview of existing gas treatment technologies, organized into acid gas removal technology and sulfur recovery technology.

Book excerpt: The objectives of this work are to (1) demonstrate on a bench-scale the Direct Sulfur Recovery Process (DSRP) for up to 99% or higher recovery of sulfur (as elemental sulfur) from SO2-containing regeneration off-gases produced in integrated gasification combined cycle (IGCC) power generating systems employing hot-gas cleanup and (2) promote DSRP technology transfer to industry. The treatment of SO2-containing regeneration off-previously (Gangwal and McMichael, 1991). Technology transfer activities have involved meetings with several industrial organizations, presentations at national scientific conferences, and experiments to evaluate DSRP's potential for treating various H2S-containing gases such as low-quality natural gas (LQNG) and amine regeneration gas. This paper will discuss the results of DSRP experiments with H2S-containing gases.
