摘要
A method of using an ammonia desulphurization technology to efficiently remove acidic gas sulfide comprises the following steps: 1) preprocessing: through sulfur recovery, acid preparation and/or incineration preprocessing methods used for acidic gas, converting remaining sulfur in the acidic gas into sulfur oxides and obtaining acidic tail gas comprising the sulfur oxides, wherein the acidic gas comes from a petrochemical industry, a natural gas chemical industry, and a coal chemical industry and the like; 2) ammonia absorption of the sulfur oxides: feeding the acidic tail gas comprising the sulfur oxides into an ammonia absorption apparatus and using circulating absorption liquid to absorb the sulfur oxides; 3) ammonium sulfate post-processing: after saturated or nearly saturated absorption liquid that fully absorbs the sulfur oxides are condensed, crystallized, solid-liquid separated and dried, a solid ammonium sulfate product is obtained. The sulfur oxides (sulfur dioxide, sulfur trioxide and a hydrate thereof) in the acidic tail gas is removed, sulfuric acid, sulfur and ammonium sulfate are produced, and clean gas discharge up to standard.
