Discussion on ammonia purification process
Thread Content
Currently, there are three main processes for ammonia purification in China: 1. Concentrated ammonia wash – advanced desulfurization adsorption; 2. Ammonia crystallizer – advanced desulfurization adsorption; 3. Concentrated ammonia wash – ammonia crystallizer – advanced desulfurization adsorption. Why are these three processes available? It seems that the first option is simpler. Is the scope of application of the second option different from that of the first? And is the third option not very necessary?
It involves multiple processes and significant investment, but it has good adaptability.
