Acid gas fractionation process for fossil fuel gasifiers

Mar 27, 1995 · The paper shows a case where a cellulose acetate membrane system can be used to reach pipeline specification for carbon dioxide and hydrogen sulfide in two stages, starting with a feed content of 15% carbon dioxide and 250 ppm hydrogen sulfide, and points out that, for high concentrations of hydrogen sulfide, "a much larger number of elements Acid gas treating - ScienceDirectJan 01, 2006 · The corrosiveness nature of hydrogen sulfide and carbon dioxide in the presence of water (giving rise to an acidic aqueous solution) and because of the toxicity of hydrogen sulfide and the lack of heating value of carbon dioxide, natural gas being prepared for sales is required to contain no more than 5 ppm hydrogen sulfide and to have a heating value of no less than 920 to 980 Btu/scf.

Appendix PA:Performance Assessment

The generation of carbon dioxide (CO 2), hydrogen sulfide (H 2 S), and methane (CH 4) by anaerobic microbial consumption of waste containing CPR materials. Coupling these gas-generation reactions to fluid-flow and salt-creep processes is complex. Atmospheric Emissions Survey of the Sour Gas Processing The generally required specification for pipeline gas is an l^S content of "no more than one-quarter grain I^S per 100 standard cubic feet of gas". This is approximately 4 x 10"^ mole fraction of t^S, or 4 parts per million by volume, or 6 mg of H^S per normal cubic meter of gas.

Cardo-type random co-polyimide membranes for high

Mar 15, 2018 · In case of high content of sour gas mixtures (20 vol% H 2 S in the feed gas), the membrane exhibits CO 2 /CH 4 and H 2 S/CH 4 ideal selectivities in the range of 1823 and 1921 respectively; and CO 2 and H 2 S permeabilities in the range of 3851 and 4047 barrers respectively. These values and separation performance exhibited by the random co-polyimide are comparable and very competitive even, as compared to the values obtained in some of the high Catalytic platinum-based membrane reactor for removal of Sep 19, 1994 · The basis for this economic calculation is a 30 MM SCFD sour-gas stream containing 0.5% H2S at a pipeline pressure of 1000 psig. With our current membrane performance, we estimate the processing cost to be about $12/1000 SCF of gas treated.

The CO 2 of the associated gas is in high partial pressure and, therefore, can be separated easily with less energy than

Natural Gas Sweetening

Natural Gas Sweetening 7.1 INTRODUCTION Natural gas, while ostensibly being hydrocarbon in nature, contains large amounts of acid gases such as hydrogen sulfide (H 2 S) and carbon dioxide (CO 2). 1 In addition to acid gases, natural gas may contain other contami-nants such as mercaptans (R-SH) and carbonyl sulfide (COS) and carbon disulfide (CS 2 PDH Courses Online.

Process and Environmental Technology for Producing SNG

It includes:(1) the production of substitute natural gas (SNG) from coal, crude oil and naphtha, (2) importing overseas gas supplies in the form of liquefied natural gas (LNG) and as liquid methanol, (3) the regasification of LNG, (4) the pro- duction of liquid fuels from oil shale, and (5) the liquefac- tion of coal to produce clean fuels.(DOC) A Methodology to Calculate Acid Gas Partial The H2S partial pressure can be calculated using the conventional approach assuming the [H2S]W equals the mol fraction of H2S in the gas. For the case study, 5.85 ppm H2S in the water translates to 0.07 psi and 0.032 psi at 12,500 psi and 5446 psi, respectively.
