Collecting carbonic anhydride is mainly chemical absorption method at present, and chemical absorption method carries out CO
2The technological process of capture and desorb is: flue gas CO
2Enter from the bottom, absorption tower, adverse current upwards contacts for 40 ℃ with the lean solution that cat head adds in the absorption tower, sloughs institute's carbonated in the flue gas, goes out CO again behind the cat head washing section
2The absorption tower is from CO
2Absorb 45 ℃ of rich solutions that come out at the bottom of the Tata and enter CO
2Stripping tower top flash zone discharges a part of CO
2, 43 ℃ of semi lean solutions that come out from flash zone bottom ℃ enter stripping section by heat temperature raising to 102.1, at CO
2The heat of vaporization that provides by the steam boiling device in the stripping section goes out a large amount of water vapours, and gas proposes CO in the solution gradually from bottom to top
2, the gas that comes out in the top is through CO
2The stripping tower condenser send compressibility after separating again.
One adopts filler or enlarging pipeline traditional desorber flash zone, and stripping section then adopts tube heater that the semi lean solution that has absorbed carbon dioxide is carried out boiling, for boiler, because exhaust gas volumn is big, CO
2Concentration height, separation equipment bulky, energy consumption is high causes present flue gas decarbonization cost also very high, CO
2Capture cost up to 40 dollars/ton about, have only and reduce its cost significantly, just might implement carbon and capture and seal up for safekeeping, and the core that reduces cost is to reduce the energy consumption of heating desorption carbon dioxide.
