Low-quality natural gas sulfur removal/recovery with membranes

Description: The main objective of this program is to develop a membrane process for the separation of hydrogen sulfide and other impurities (carbon dioxide and water vapor) from low-quality natural gas. The overall program involves development and parametric testing of appropriate membrane materials in the form of thin-film composite membranes. These membranes will then be made on a larger scale and incorporated into modules which will be tested first in the laboratory, and then at different field sites. A… more

Novel Technologies for Gaseous Contaminants Control

Description: Overall objective of this project was to develop a technology platform for cleaning/conditioning the syngas from an integrated gasification combined cycle (IGCC) system at elevated temperatures (500-1,000 F) and gasifier pressures to meet the tolerance limits for contaminants, including H{sub 2}S, COS, NH{sub 3}, HCl, Hg, and As. This technology development effort involved progressive development and testing of sorbent/catalytic materials and associated processes through laboratory, bench, pilo… more

Low-quality natural gas sulfur removal/recovery

Description: 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… more
