Abstract

Present invention can apply to produce the industry of sulfur-bearing, ammonia-contaminated gas, such as coal chemical industry simultaneously.The invention is that low-temp methanol in coal chemical industry is washed into sour gas to introduce sulfur recovery unit progress CLUS reaction Recovered sulphur out of sulfur recovery unit sulphur stove, stripper generation sour gas containing ammonia (also known as converting fixed gas), which is introduced into sulfur recovery unit tail gas burning furnace, to be burned (ammonia is not decomposed and burnt at this temperature), the flue gas containing sulfur dioxide, ammonia after burning enters ammonia process of desulfurization workshop section reaction generation sulfate of ammoniac, so as to reach the comprehensive utilization of sulphur, ammonia.

Description

Coal chemical industry sulfur-bearing, ammonia-contaminated gas handling process
Technical field：
The present invention is handled applied to sulfur-bearing, the ammonia-contaminated gas of coal chemical industry.
Technical background：
With the reinforcement of environmental improvement, new pollutant emission standard《Petro chemical industry pollutant emission standard GB31571-2015》Promulgation, it is desirable to discharge SO 2 in waste gas concentration less than 100mg/m3, Special section sulfur dioxide emissioning concentration is less than 50mg/m3.Traditional sulfur recovery technology, or even clus+scot techniques can not all meet discharge standard requirement, it is necessary to clus sulphur tail gas is further processed, such as ammonia process of desulfurization, alkali desulphurization.
The content of the invention：
The invention is that low-temp methanol in coal chemical industry is washed into sour gas to introduce sulfur recovery unit progress CLUS reaction Recovered sulphur out of sulfur recovery unit sulphur stove, stripper produces sour gas containing ammonia (also known as converting fixed gas) introducing sulfur recovery unit tail gas burning furnace and burned, by hydrogen sulfide therein, carbon monoxide, oxidation of hydrogen is into sulfur dioxide, carbon dioxide, water, (700 DEG C or so) are not burned and decomposed substantially ammonia at this temperature, contain sulfur dioxide after incinerator burning, the flue gas of ammonia enters ammonia process of desulfurization workshop section reaction generation sulfate of ammoniac, so as to reach sulphur, the comprehensive utilization of ammonia, sulphur, the discharge of ammonia reaches《Petro chemical industry pollutant emission standard GB31571-2015》Emission request.
Brief description of the drawings：
Accompanying drawing is that sulfur-bearing ammonia-contaminated gas reclaims comprehensive utilization schematic diagram.
Embodiment：
Low-temp methanol in coal chemical industry is washed into sour gas and passes through CLUS sulfur recovery units one section of high temperature of progress, two-stage low temperature catalytic reaction Recovered sulphur, the sour gas containing ammonia (also known as converting fixed gas) that conversion stripper is produced is burned into CLUS sulfur recovery unit tail gas burning furnaces, by hydrogen sulfide therein, carbon monoxide, oxidation of hydrogen is into sulfur dioxide, carbon dioxide, water, (700 DEG C or so) are not burned and decomposed substantially ammonia at this temperature, contain sulfur dioxide after incinerator burning, the flue gas of ammonia enters ammonia process of desulfurization workshop section reaction generation sulfate of ammoniac, so as to reach sulphur, the comprehensive utilization of ammonia, sulphur, the discharge of ammonia reaches《Petro chemical industry pollutant emission standard GB31571-2015》Emission request.

Claims (1)

1. the invention is that stripper is produced into sour gas containing ammonia to introduce in sulfur recovery unit (clus) tail gas burning furnace, in the lower progress of 700 DEG C of temperature or so Burn, by hydrogen sulfide therein, carbon monoxide, oxidation of hydrogen into sulfur dioxide, carbon dioxide, water, ammonia is at this temperature (700 DEG C or so) Substantially it is not burned and decomposes, the flue gas containing sulfur dioxide, ammonia after incinerator is burned enters ammonia process of desulfurization workshop section reaction generation sulfate of ammoniac, so that Reach the comprehensive utilization of sulphur, ammonia.The progress at a temperature of 1300 DEG C or so in sulfur recovery unit (clus) sulphur stove processed is introduced with ammonia sour gas will be contained in the past Decompose completely and reach that the qualified discharge technique of ammonia is compared, with following technical characteristics：
1st, the energy consumption that ammonia is introduced needed for sulphur stove pyrolytic processed is saved；
2nd, sulfur recovery unit load is reduced, sulfur recovery unit investment is saved；
3rd, avoid ammonia not decompose fully, cause acceleration of the ammonia to sulfur recovery unit catalyst sulfuric acid salinization to promote, so as to influence the steady production of device With catalyst service life.
4th, the ammonia for having recycled the sour gas containing ammonia carries out the further ammonia process of desulfurization to sulphur tail gas processed.Save the cost that ammoniacal liquor is bought in the ammonia process of desulfurization.
The invention claim is as follows：
(1) low-temp methanol in coal chemical industry is washed sour gas and sulfur recovery unit progress CLUS reaction recovery sulphur is introduced out of sulfur recovery unit sulphur stove by protection Sulphur, stripper produces sour gas containing ammonia (also known as converting fixed gas) introducing sulfur recovery unit tail gas burning furnace and burned, after incinerator is burned The flue gas containing sulfur dioxide, ammonia enter ammonia process of desulfurization workshop section react generation sulfate of ammoniac exhaust-gas treatment group technology route.
