Ammonia gas is absorbed with water
Thread Content
The data packets were called; there is no condensation at the top of the tower. The ammonia gas exiting the tower is cooled to the feed temperature (with a meteorological fraction set to 0, the pressure is 0.7 MPa, while the pressure in the ammonia absorption tower is at atmospheric pressure of 0.1 MPa), after which it is circulated back to the tower. Water enters the tower from the top, and as a result, an ammonia water concentration of around 17% is obtained. The question is: I’m not sure what the industrial practice for absorbing ammonia gas using water looks like; no relevant examples could be found. I’d like to analyze this matter – please advise
I would like to ask if your ammonia solution with a concentration of around 17% has any odor leaks, and what measures or equipment are in use to address this?
Using water for absorption in industrial applications is not very effective; these days, dilute sulfuric acid is generally used for absorption, with sulfuric anhydride being produced as a by-product
