| Abstract: | Using caprolactam（CPL） and tetrabutyl ammonium bromide（TBAB） as raw material,CPL-TBAB ionic liquid is synthesized by the mole ratio of 2 ∶ 1,the prepared ionic liquid is mixed with ethanol by the volume ratio of 1.5 ∶ 1 to decrease the viscosity.Sieve-plate tower was used to absorb in order to investigate the optimum conditions and absorption efficiency.The results show that experimental conditions which generate the best absorption efficiency are as follows： ionic liquid flow rate 60 L/h,SO2 flow rate 0.2 L/min,temperature SO2 30℃ and maximum value of the absorption is 47.6%. |
