摘要： The composite amine absorbing solution according to the present invention absorbs CO 2 or H 2 S or both in a gas, and is obtained by dissolving (1) a linear monoamine, (2) a diamine, and (3) an amide group-containing compound in water. By adopting this composite amine absorbing solution, the composites are interacting in a composite manner, due to an integrated effect of the components, the absorption property of CO 2 or H 2 S or both is favorable, the desorption properties of the CO 2 or H 2 S absorbed when regenerating the absorbing solution become favorable, and the amount of steam from a reboiler 26 used when regenerating the absorbing solution in a CO 2 recovery device 12 can be reduced.

摘要： This invention relates to a reducing agent supply device and an exhaust gas denitrification system using the same. The reducing agent supply device includes a reducing agent supply unit for supplying a reducing agent to a selective supply unit, a water supply unit for supplying water to the selective supply unit, the selective supply unit for selectively supplying any one of the reducing agent and water supplied from the reducing agent supply unit and the water supply unit to a spray unit, and the spray unit for spraying the reducing agent or water supplied from the selective supply unit, wherein the selective supply unit supplies water to the spray unit when the spray unit is blocked due to solidification of the reducing agent which remains behind therein because of a process in which the spray unit continuously sprays the reducing agent or a temporary malfunction of the device, thereby preventing blockage of the spray unit. Also an exhaust gas denitrification system using the device is provided.

摘要： 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).

摘要： Sodium borohydride (NaBH 4 ) may be used to removing carbonyl sulfide (COS) from a process stream containing it. The method involves contacting the process stream with an amount of effective of NaBH 4 to react with the COS to form reaction products that may be removed by a process of washing away the reaction product by an aqueous basic compound and/or the reaction product having a higher boiling point than carbonyl sulfide which permits trapping the reaction product, such as in a caustic tower.

摘要： A method and plant for capturing CO2 from a CO2 containing exhaust gas (1), where the exhaust gas is compressed (10) and thereafter cooled (13, 15, 22) before the exhaust gas is introduced into an absorber (30), where the exhaust gas is brought in counter-current flow with an aqueous CO2 absorbent solution (49), to give a lean exhaust gas (31) that is withdrawn from the absorber (30), reheated 22, 13) against incoming compressed exhaust gas, and thereafter expanded (34) and released into the atmosphere (4), where the aqueous CO2 absorbent solution is an aqueous potassium carbonate solution, and that the steam and CO2 withdrawn from the regenerator (40) is cooled in a direct contact cooler (61) by counter-current flow of cooling water (62), to generate a gaseous flow (70) of cooled CO2 and steam that is withdrawn for compression and drying of the CO2, and a liquid flow (64) of cooling water and condensed steam that is withdrawn and flashed (80), to give a cooled liquid phase (84) that is recycled as cooling water for the direct contact cooler (61) for the withdrawn CO2 and steam, and a gaseous phase (81) that is compressed (82) and thus heated, and introduced into the regenerator (40) as stripping steam (83).
