Abstract: Provided are a CO 2 recovery unit and a CO 2 recovery method with which it is possible for a CO 2 recovery amount and/or a CO 2 recovery rate to be controlled with high accuracy towards a target value. This CO 2 recovery unit (1) is characterized by being equipped with: a CO 2 absorber (14) that causes CO 2 included in flue gas (11A) to be absorbed into a CO 2 -absorbing solution (13); a CO 2 -absorbing solution regenerator (15) which, by heating, regenerates the CO 2 -absorbing solution (13) that has absorbed the CO 2 ; a CO 2 recovery rate control unit which measures the CO 2 concentration in the flue gas (11A) and which, on the basis of the CO 2 concentration in the flue gas discharged from the CO 2 -absorbing solution (13) that has absorbed the CO 2 , changes the absorbing solution circulation amount and the amount of saturated steam (S) that is supplied to a regeneration heater (31); and a CO 2 recovery amount control unit which, in accordance with the CO 2 concentration of the flue gas (11A) and the flue gas flow rate, changes the circulation amount of the CO 2 -absorbing solution (13) and the amount of the saturated steam (S) supplied to the regeneration heater (31).

Abstract: The present invention relates to a gas-redirecting device (100) presenting an upper plane and a plurality of gas-redirecting tubes (3) comprising an inlet end and an outlet end. For each gas-redirecting tube, the orthogonal projections of the inlet end and the outlet end onto the upper plane have an over-lapping area of at most 50 % of the total area of the upper plane covered by the orthogonal projections. The present invention also relates to a liquid-gas contacting column (201) comprising such a gas-redirecting device (100), a floating support comprising such a liquid-gas contacting column, at least two packed beds (210, 220) and a method for improving the efficiency of a liquid-gas contacting column which is based on redirecting the gas from a wetted zone of a lower packed bed to a wetted zone of the higher packed bed, the liquid load through the wetted zone of the lower packed bed is different from the liquid load through the wetted zone of the higher packed bed.

Abstract: Disclosed is a method of removing carbon dioxide from a process gas, the method comprising: contacting an ammoniated solution with the process gas in an absorption arrangement 101, the ammoniated solution capturing at least a part of the carbon dioxide of the process gas, wherein the molar ratio, R, of ammonia to carbon dioxide in the ammoniated solution is controlled such that substantially no precipitation of solids occurs within the absorption arrangement 101; allowing ammoniated solution including captured carbon dioxide to exit the absorption arrangement 101; cooling the ammoniated solution that has exited the absorption arrangement, wherein at least a part of the captured carbon dioxide is precipitated as solid salt; separating at least a part of the precipitated salt from the ammoniated solution; heating the ammoniated solution from which the at least a part of the precipitated salt has been separated, such that substantially no solids are present in the heated ammoniated solution; and allowing the heated ammoniated solution to re-enter the absorption arrangement 101. Disclosed is also a system for removal of carbon dioxide from a process gas.

Abstract: An air quality control system (AQCS) (200) is configured to clean a process gas (106). The AQCS includes a gas cleaning device (202) that receives a process gas (106) containing pollutants and a clean fluid flow (206). The process gas (106) is contacted with the clean fluid flow (206) to remove the pollutants from the process gas (106). Contact of the process gas (106) with the clean fluid flow (206) generates a clean exhaust gas flow (108) and an effluent fluid flow (208). A fluid conduit (228) receives the effluent fluid flow (208) discharged from the gas cleaning device (202), and defines a fluid column (209) height (H) of effluent fluid flow (208). The effluent fluid flow (208) therefore has an amount of kinetic energy based on a height of the fluid column (209). An energy recovery device (210) receives the effluent fluid flow (208) from the fluid conduit (228). The energy recovery device (210) converts a portion of the amount of kinetic energy of the effluent fluid flow (208) to mechanical work.
