摘要： PROBLEM TO BE SOLVED: To provide a system capable of still more effectively recovering carbon dioxide and other substance to be adsorbed from an oxygen-containing fed substance by using an alkanolamine based adsorbent for enhancing the grade of the fed substance. SOLUTION: Lean fed gas 1 is sent to a blower 2 to be compressed and this compressed lean fed gas 3 is sent to the lower part of an adsorption tower 4 from the blower 2. An adsorbent 6 is a fluid containing at least one alkanolamine species being primary or secondary alkanolamine and the lean fed gas rises against the flowing-down adsorbing material in the adsorption tower 6. As the lean fed gas rises, almost all of carbon dioxide and a small amt. of other substance to be adsorbed in the gas are adsorbed by the flowing- down adsorbent and vapor reduced in the content of carbon dioxide is collected at the upper position of the adsorption tower 6 and the adsorbent loaded with carbon dioxide containing dissolved oxygen is collected at the bottom position thereof.

摘要： PROBLEM TO BE SOLVED: To effectively recover carbon dioxide by passing an O2 and CO2- containing material mixture through an absorbent containing an alkanol amine to be in contact counter currently to absorb O2 and CO2 and after separating O2 from the CO2-loaded absorbent, getting a high concentration CO2-containing fluid by heating. SOLUTION: The compressed feed material gaseous mixture 3 is sent to the bottom of an absorption column 4 with 40-50 deg.C in the upper part and 50-60 deg.C in the lower part, by a blower 2. The absorbent flow 6, which is a 5-80 wt.% aq. solution of monoethanol amine, or the like, is brought into counter currently contact. The O2 and CO2 loaded absorbent in a flow 7 is brought into counter currently contact with an oxygen removing gas in an oxygen stripping column 151 to be reduced in O2 content into

摘要： PROBLEM TO BE SOLVED: To provide an efficient method for recovering carbon dioxide of high pressure directly from a low-pressure feed stream. SOLUTION: The feed stream 1 is brought into contact with a liquid absorbent fluid in an absorber for recovering carbon dioxide. The carbon dioxide in a gaseous feed stream 1 is absorbed preferentially by the absorbent in the liquid absorbent fluid to generate a liquid absorbent stream 7 rich in carbon dioxide. The stream 7 is withdrawn from the bottom of the absorber 4 and sent to a rich solvent pump 8. The stream 7 is compressed by the pump 8 to have 0.241325 MPa (35 psia) or higher absolute pressure enough for the stream 7 to reach to the top of a stripping apparatus 12.

摘要： PROBLEM TO BE SOLVED: To recover carbon dioxide without adding an inhibitor, in recovering carbon dioxide from air by absorption of the same with a recovery solvent based on an amine, by separating carbon dioxide from a carbon dioxide absorbing/recovering solvent to form a fluid rich in carbon dioxide to recover the same. SOLUTION: Supplied air 1 is raised in its pressure by a compressor or blower 2 to be passed through an absorbing tower 4 from the lower part thereof and, when this air rises through a recovery solvent 6 based on an amine, carbon dioxide in the supplied air is absorbed by the recovery solvent 6. Thereafter, carbon dioxide excluding vapor is gathered to the top part of the tower 4 while the carbon dioxide absorbing recovery solvent is gathered to the bottom part of the tower 4 and both of them are drawn out to the outside. The drawn-out carbon dioxide absorbing recovery solvent is next guided to a heat exchanger 10 by a liquid pump 8 and heated to be passed through the upper part of a stripping tower 12 to be separated into top part vapor rich in carbon dioxide and the remaining amine recovery solvent and both of them are recovered by separate routes.

摘要： A carbon capture enabled system and method for generating electric power and/or fuel from methane containing sources using oxygen transport membranes by first converting the methane containing feed gas into a high pressure synthesis gas. Then, in one configuration the synthesis gas is combusted in oxy-combustion mode in oxygen transport membranes based boiler reactor operating at a pressure at least twice that of ambient pressure and the heat generated heats steam in thermally coupled steam generation tubes within the boiler reactor; the steam is expanded in steam turbine to generate power; and the carbon dioxide rich effluent leaving the boiler reactor is processed to isolate carbon. In another configuration the synthesis gas is further treated in a gas conditioning system configured for carbon capture in a pre-combustion mode using water gas shift reactors and acid gas removal units to produce hydrogen or hydrogen-rich fuel gas that fuels an integrated gas turbine and steam turbine system to generate power. The disclosed method and system can also be adapted to integrate with coal gasification systems to produce power from both coal and methane containing sources with greater than 90% carbon isolation.
