标 题 :Aqueous absorbent composition for enhanced removal of hydrogen sulfide from gaseous mixtures and method for using the same
发明人：LAROCHE CHRISTOPHE R; PADILLA GERARDO; HALNON TIMOTHY D
权利人:DOW GLOBAL TECHNOLOGIES LLC
摘要:The present invention relates to an aqueous alkanolamine solution for the removal of hydrogen sulfide from gaseous mixtures containing hydrogen sulfide. The aqueous alkanolamine solution comprises (i) an amino compound with the formula:n nR 1 R 2 NCH 2 CH(OH)CH 2 OHn nwherein R 1 and R 2 independently represent lower alkyl groups of 1 to 3 carbon atoms, (ii) piperazine, and (iii) optionally a physical solvent, wherein said solution does not contain a strong acid. Further, the present invention relates to a process for removing hydrogen sulfide from a gaseous mixture containing hydrogen sulfide, and additionally other acid gases, if present, for example carbon dioxide, comprising the step of contacting the gaseous mixture contain hydrogen sulfide with the aqueous alkanolamine solution, preferably wherein the temperature of the aqueous alkanolamine solution is equal to or greater than 140° F. Examples of the gaseous mixtures include natural gas, synthesis gas, tail gas, and refinery gas.

摘要:An aqueous solution containing from 0.81 to 1.3 moles of piperazine per liter is used as a washing agent for removing impurities such as H 2 S, CO 2 and COS from gases. Piperazine can also be used, in amounts of up to 0.8 mole per liter, together with physical or chemical solvents, to accelerate the absorption of H 2 S, CO 2 and COS. The washing process is used for natural gases, coke-oven gases, gases from the gasification of coal and synthesis gases, of any origin.

摘要:This invention relates to spreading pastes containing polyurethanes which are prepared from special synthesis components selected from the group of silicone resins, polyethers or polyesters containing aromatic segments or perfluorocarbon resins. The spreading pastes also contain organic solvents and optionally non-solvents for the polyurethanes so that when the coatings are used to coat textile substrates according to the direct or transfer process, the coatings may be cured based on the principle of evaporation coagulation.
