In the production of chemical plants, the problem of generating tail gas is always a difficult problem to be solved urgently, the tail gas generated by our company is mainly organic gas such as toluene, xylene and the like, if direct emission is not allowed, in the cooling and washing processes of coal gasification and gasification gas of new energy sources such as coal chemical industry, methanol, ether, dimethyl ether and the like and chemical enterprises, because the temperature is reduced and the pressure is higher, a large amount of ammonia gas, carbon dioxide, a small amount of hydrogen sulfide, carbon monoxide, hydrogen and the like are condensed and dissolved in condensate, and a conversion gas condensate rich in ammonia gas and carbon dioxide is formed. Wherein the carbon dioxide content is 10-20g/L, the ammonia gas content is 4-8g/L, the hydrogen sulfide content is 0.1-0.3g/L, the carbon monoxide content is 0.2-0.5g/L, and the hydrogen gas content is 0.02-0.1/L. The conversion condensate belongs to high ammonia nitrogen wastewater and cannot be directly discharged, if the conversion condensate is introduced into a wastewater biochemical treatment system of an enterprise, the ammonia nitrogen load of the biochemical system is directly increased, the wastewater cannot be discharged up to the standard, most enterprises remove ammonia nitrogen and carbon dioxide by adopting a gas stripping ammonia evaporation mode, and qualified liquid after gas stripping is recycled to an enterprise gasification system. Because the temperature of the mixed gas after the gas stripping is condensed is 60-80 ℃, the content and the water content of ammonia gas are higher, a sulfur recovery system and a torch in the later period are frequently flamed out, the normal operation cannot be realized, and new nitrogen oxide pollution is easily formed; in addition, when the mixed gas stripped out from the tower is condensed at the top of the tower, ammonium carbamate and hydrogen sulfide are greatly enriched at the bottom of the condenser, the concentration is greatly increased, the condenser is seriously corroded and cannot be used in less than three months, and therefore most enterprises directly discharge the part of gas (stripping tail gas) to form more serious atmospheric pollution.
