Abstract：The influences of different drainage structures on the gas?liquid separation performance of wave-plate mist eliminator were analyzed and the parameters of drainage structure were optimized by response surface methodology. The single factor experiment was used to select the key parameters which had significant influence on the performance of the mist eliminator. The multivariate regression model was established using center compound design experiment in order to analyz the interaction of parameters which had influence on mist eliminator performance coefficient. The results showed that the key parameters which had significant influence on the performance of the mist eliminator and their values were separation gas velocity 2.6 m/s, height of drainage hook 7.3 mm, width of front-drainage pocket 3.1 mm and width of rear-drainage pocket 2.3 mm. The calculated value of mist eliminator performance coefficient was 2.073 while the test value was 1.875 which indicated that the optimization result of response surface methodology was credible.
