摘要： A flue gas-treating method for treating acid tail gas by using an ammonia process, comprising the following steps of: 1) controlling the concentration of sulfur dioxide in an acid tail gas entering an absorber to be ≦30,000 mg/Nm3; 2) spraying and cooling with a process water or/and an ammonium sulfate solution in the inlet duct of the absorber or inside the absorber; 3) providing an oxidation section in the absorber, wherein the oxidation section is provided with oxidation distributors for oxidizing the desulfurization absorption solution; 4) providing an absorption section in the absorber wherein the absorption section achieves desulfurization spray absorption by using absorption solution distributors via an absorption solution containing ammonia; the absorption solution containing ammonia is supplied by an ammonia storage tank; 5) providing a water washing layer above the absorption section in the absorber, wherein the water washing layer washes the absorption solution in the tail gas to reduce the slip of the absorption solution; 6) providing a demister above the water washing layer inside the absorber to control the concentration of mist droplets contained in the cleaned tail gas. In the coal chemical industry, the integration of the Claus sulfur recovery process and the ammonia desulfurization technology can reduce the investment of the post-treatment and simplify the operation process, and provide intensive advantages to the environmental control of plants.

摘要： A method for effectively removing acidic sulfide gas using ammonia-based desulfurization includes the following steps of: 1) pre-treatment, wherein sulfide in acid gas undergoes through pre-treatment methods of sulfur recovery, acid making or/and incineration to convert remaining sulfur in the acid gas into sulfur oxides, and the acid tail gas with sulfur oxides is obtained; and the acid gas is derived from petrochemical industry, natural gas chemical industry, coal chemical industry, etc.; 2) ammonia absorption of sulfur oxides, wherein the acid tail gas with sulfur oxides is allowed to flow into an ammonia absorption apparatus, and a cyclic absorption solution is used to absorb sulfur oxides; and 3) post-treatment of ammonium sulfate, wherein a saturated or nearly saturated absorption solution undergoes concentration, crystallization, solid-liquid separation, and drying to obtain a solid product of ammonium sulfate. Sulfur oxides (including sulfur dioxide, sulfur trioxide and hydrates thereof) in the acid tail gas are removed and sulfuric acid, sulfur and ammonium sulfate are byproduced, and the cleaned gas is discharged upon meeting the emission standard.
