Liquid ammonia finishing and processing process has exhaust gas, its composition is water vapor, air and ammonia, ammonia is a harmful gas, affect the health and pollution of the environment, to reduce emissions, strengthen recovery, on the one hand can reduce the cost, on the other hand can protect the environment.

Absorption of ammonia recovery, the expulsion of gas from the liquid ammonia finishing machine, through pipes to the recycling equipment washing tower (absorption tower), the mixed with ammonia in the air in the tower of the water absorption of ammonia, the air is clean outside the tower side by side, and then through the ammonia distillation tower and water separation, made strong aqua ammonia absorbed by distillation, the meridian of concentrated ammonia distillation into thick ammonia, then concentrated ammonia compressor pressure and condensing cooling liquid ammonia, and finally enter the storage tank.
