【Abstract】 Thermodynamic computation and analysis are conducted of the proc ess in which pyrolusite absorbs SO 2 with main and auxiliary towers in series. Its absorption conditions are investigated by orthogenal experiments and its tec h nological feasibility is demonstrated. It is concluded that when the main tower’ s temperature is 80 ℃, the auxiliary tower’s temperature is 50 ℃ ,the S/L r atio is 1∶6 and the reaction time is 35 min, the desulphurization rate and conversi on ratio are above 90%, respectively.更多还原
