The feed gas contains 200 ppm of ammonia; it is necessary to determine the diameter, height of the absorption tower, and the height of the packing layer using water absorption. Q_in = 82,000 Nm3/h, P_work = 5.2 MPa(G); the ammonia content is 200 ppm, and it is required that the ammonia content be 3 ppm after absorption. If the ammonia recovery concentration is 10%, what are the amounts of water absorbed and the amount of water to be added? @
Absorb it with fresh water? The amount of water can be calculated based on material balance.
Ignoring the heat of absorption and release, the theoretical packing height can be calculated using the number of mass transfer units x the height of each mass transfer unit as given in textbooks on chemical engineering principles.
There is a feed gas containing 200 ppm of ammonia, and water absorption is used to determine the diameter, height of the absorption tower, and height of the packing layer. Q_in = 82,000 Nm3/h, P_work = 5.2 MPa(G); the ammonia content is 200 ppm, and it is required that the ammonia content be 3 ppm after absorption. If the ammonia recovery concentration is 10%, what are the amounts of water absorbed and the amount of water to be added? Water absorption rate: 1500 kg/h; Water replenishment rate: 122.6 kg/h

Our factory has an ammonia separation tower, designed by Kefukai; I don’t know much about it!
I can’t do the calculation; let’s see how the experts do it
