Method For Producing Ammonium Sulfate

After being neutralized by ammonium hydroxide and sulfuric acid, it is obtained by crystallization, centrifugation and drying. Neutralization of ammonia and sulfuric acid is carried out at about 100 ° C for neutralization reaction, and the resulting ammonium sulfate crystal slurry is centrifuged and dried to obtain a finished ammonium sulfate. The 2NH3+H2SO4→(NH4)2SO4 recovery method is obtained by recovering ammonia gas from coke oven gas and neutralizing it with sulfuric acid.
