Abstract:

On condition of not changing the column body of original ammonia stripper and deacidifier,this paper presents the method of replacing original internals with new type vertical sieve trays,which has solved the problem of insufficient capacity and effect of ammonia stripping process.The capacity could be increased to 200~280m3/h from 133m3/h,and at the same time the parameters of ammonia stripping and deacidifier could meet the requirement of original design,so that it has achieved the effect of high yield with lower energy consumption.
