Phosphate absorption of ammonia
Thread Content
That expert is familiar with the process design for phosphoric acid to absorb ammonia and the entire workflow.
It seems that there isn’t yet any mature experience with this approach in China; I’ve only heard that a certain project is using this method, with foreigners handling the process design. I don’t know what that project is. Are you trying to recycle waste gas?
Is phosphoric acid used to wash ammonia-containing exhaust gases?
1# suiran983527 I know a little about it; the process is relatively simple. It involves using an acidic phosphoric acid solution to absorb ammonia, with the pH kept around 2. After absorption, the solution is simply treated to allow for the separation of ammonia and phosphoric acid, thereby enabling their recovery
