摘要： The gaseous effluent to be treated is contacted in C1 with an absorbent solution selected for its property of forming two separable phases when it has absorbed an amount of acid compounds and when it is heated. The absorbent solution laden with acid compounds is then heated in E1 and E3 so as to separate two fractions in BS1: a first absorbent solution fraction depleted in acid compounds and a second absorbent solution fraction enriched in acid compounds. The second fraction is regenerated in C2 so as to release part of the acid compounds, and the first absorbent solution fraction and the regenerated absorbent solution are recycled as absorbent solution.According to the invention, an absorbent solution portion circulating in C1 is cooled in E2 in order to prevent demixing of the solution in column C1.

摘要： The invention relates to a process and a device for carrying out a gas scrubbing, in which gas is conducted from bottom to top and scrubbing medium is conducted from top to bottom through a scrubbing column (T). In the scrubbing column (T) at least two scrubbing sections (WS1 and WS2) are arranged one above the other, of which the upper is restricted downwards by a chimney tray (K). From the chimney tray (K) at least some of the scrubbing medium loaded in the upper scrubbing section (WS2) is taken off at a take-off point (A) provided in the region of the chimney tray (K) and introduced as scrubbing medium into the lower scrubbing section (WS1) at an introduction point (E) provided in the region of the lower scrubbing section (WS1). A heat-exchange appliance (6) is connected in series in the direction of flow downstream of the take-off point (A) and upstream of the introduction point (E). The flow through the heat exchanger (6) is ensured solely by the hydrostatic pressure of the scrubbing medium which is given by the height difference between the take-off point (A) and the introduction point (E). A pump is dispensed with in this case.

摘要： A CO2 recovery apparatus according to the present invention includes: an absorber (1003) that brings CO2-containing flue gas (1001A) into counter-current contact with CO2 absorbent (1002) to reduce CO2, and a regenerator (1005) that regenerates rich solution (1004) that has absorbed CO2, in which lean solution (1006) having CO2 reduced in the regenerator (1005) is reused in the absorber (1003). The absorber (1003) further includes a CO2 absorbing unit (1010) that recovers CO2 contained in the flue gas (1001A), and the CO2 absorbent (1002) that has absorbed CO2 is extracted from a rich side of the CO2 absorbing unit (1010) to exterior, cooled, and then supplied to a position nearer to a lean side of the absorber (1003) with respect to the position at which the CO2 absorbent (1002) is extracted.
