Abstract: Systems and methods for removing carbon dioxide from a combustion flue gas and/or air by using a high-pressure aqueous ammonia solvent and a plurality of liquid driven ejectors to absorb and remove the carbon dioxide for carbon capture utilization or storage. The aqueous ammonia solvent is regenerated at a high pressure to save potential compression energy required for the absorption and removal of carbon dioxide.

Abstract: The present invention relates to a method for combined SO2 and CO2 removal from flue gas, which includes removing both CO2 and SO2 in a primary fractionation column and two polishing columns, the method comprising: a) hot flue as pretreatment, including flue gas SO3 removal by dry sorbent injection; b) compressing the treated hot flue gas by a multi-stage compressor; c) separation of CO2, SO2 and non-condensable gases; d) subjecting the CO2 and SO2 to separate polishing columns; and e) combining streams from the primary fractionation column and the two polishing columns for power recovery.

Abstract: A method of treating gas, such as flue gas, is provided. Flue gas is received into a vessel. The flue gas in the vessel is cooled by at least 17 degrees F. to a temperature of 120 F or lower. Also in the vessel, SOx compounds are removed such that the concentration of SOx remaining in the flue gas is between 0 ppmv and 10 ppmv. After the flue gas is cooler and SOx compounds are removed in the vessel, the flue gas is transmitted to a flue gas carbon dioxide scrubbing unit.

Abstract: The invention provides methods for purifying hydrogen sulfide gas having impurities therein. In one exemplary method, the hydrogen sulfide gas is purified by passing the gas through a filter media, with at least some of the impurities being trapped within the filter media. A catalyst may also be provided to break down some of the impurities to hydrogen sulfide and sulfur, so that the sulfur may be trapped and collected within the filter media.
