【Abstract】 The algorithm of simulating stripping of sour water column is based on the method of modified triple diagonal matrix, and the modified Edwards simulation is used to compute the activity coefficient. Through computing and analyzing several causes, which include the factors affecting the operation of column, such as cold and hot feed proportioning, the concentration of ammonia and hydrogen sulfide, the position of side stream and temperature of hot feed, the best operating condition is found. The results of simulation accord with practicality and have been used to direct reconstruction of some corporations and have acquired good effects.更多还原
