Is it cost-effective to use phosphoric acid to absorb ammonia from exhaust gases in order to produce monoammonium phosphate and diammonium phosphate?
Thread Content
In hydrometallurgy enterprises, stripping equipment is used in the initial stage, along with sulfuric acid for absorption to produce sulfuric acid an. However, there are issues with exporting sulfuric acid an at the moment, so it is necessary to change the manufacturing process. Therefore, the design involves using phosphoric acid absorption to produce monoammonium and diammonium compounds; I wonder if this process is feasible? Is it worth it?
How can there be any evaluation without any data? Should we use divination?
Your question doesn’t seem to be clear. Are you referring to the ammonia washing process in the gas purification plant? Are you saying that there is a poor market for sulfuric acid produced using saturators? Are you considering using phosphoric acid to wash ammonia now? Producing monoammonium phosphate and diammonium phosphate? In coking plants, this phosphoric acid ammonia washing process is mainly used to produce anhydrous ammonia or 20% concentrated ammonia by eliminating the need for distillation towers. The several plants I visited did not produce ammonium phosphate monohydrate or diammonium phosphate; it seems advisable that you consult more sources if you have such interests
It is technically feasible, but the cost of phosphoric acid is high; the economic aspects need to be considered.
Wastewater containing phosphoric acid can be considered for neutralization to produce phosphate fertilizer; otherwise, the product will lack competitiveness.

We here would also like to inquire whether there are any companies that specialize in designing systems for ammonia recovery from exhaust gases
