SO2 removal from simulated flue gas using various aqueous solutions: Absorption equilibria and operational data in a packed column

A bench-scale test (800 Nm3/h) for electron beam treatment of flue gas was conducted. It was concluded that the method is favourable for treatment of flue gas with a high SO2 concentration (5,500 ppm) at low electron beam irradiation (5 kGy). Results are consistent with the claim that SOx is removed from flue gas by the reaction of SOx with ammonia, and the intermediate salts formed are oxidised by radicals to sulphate salts consisting mainly of ammonium sulphate (a N-fertiliser). A typical flue gas desulphurization (FGD) method such as the wet limestone process cannot remove NOx and SO3 effectively (Ando, 1990), but the electron beam process removes SO2, SO3 and NOx simultaneously without generating waste water and CO2.

Absorption Capacity

The absorption of CO2 with ethanolamine (MEA) was studied in this paper, and proper additives such as piperazine (PZ) and N- methyldiethanolamine (MDEA) were mixed in different proportion to the main reacting substance. The performance of absorbents with different formula were studied by analyzing and comparing the characteristic indexes of absorbents, including absorption rate, regeneration temperature, absorption capacity of CO2, and regeneration degree. The results have been shown that aqueous solutions added PZ could increase absorption rate and improve absorption capacity than that of MDEA, and Aqueous solutions added MDEA could decrease regeneration energy and improve regeneration degree than that of PZ. The formular of 16%MEA+4%PZ could be the most suitable absorbent of CO2 in the study.
