METHOD AND APPARATUS FOR SOx AND CO2 REMOVAL FROM FLUE GAS |
摘要 |
The present invention relates to a method for combined SO2 and CO2 removal from flue gas, which includes removing both CO2 and SO2 in a primary fractionation column and two polishing columns, the method comprising: a) hot flue gas pretreatment, including flue gas SO3 removal by dry sorbent injection; b) compressing the treated hot flue gas by a multi-stage compressor; c) separation of CO2, SO2 and non-condensable gases; d) subjecting the CO2 and SO2 to separate polishing columns; and e) combining streams from the primary fractionation column and the two polishing columns for power recovery. |
