Ammonia content in sulfur recovery
Thread Content
This post was last edited by liaifeng on 2018-9-3 08:17. In the company’s sulfur recovery unit, the ammonia content in the acidic gas is over 66%, and there is no ammonia extraction at intermediate stages during the stripping process. I would like to ask whether there are any good methods, other than extracting ammonia at intermediate stages, to separate some of the ammonia from hydrogen sulfide
Ammonia removal in the stripping intermediate stage is a conventional method!
Double-tower stripping is also a conventional method for separating hydrogen sulfide from ammonia.
Do you have any information on double-tower stripping? Can I learn it* a bit?
