Method and system for treating organic waste gas in ethephon production

The invention discloses a method and a system for treating organic waste gas in ethephon production, which are characterized in that waste gas generated in an esterification rearrangement section is subjected to two-stage water washing to obtain first waste gas, waste gas generated in other sections is rectified to obtain second waste gas, the first waste gas and the second waste gas are mixed and then subjected to two-stage alkali washing to obtain mixed waste gas, the mixed gas is subjected to deep cooling and then guided into the resin adsorption treatment device to be treated, tail gas is obtained after treatment, the tail gas is subjected to oxidation treatment and then guided into the tail control device, and by means of the method, dichloroethane in waste gas components can be recycled, ethylene in total hydrocarbon contained in the tail gas can be removed, and the treatment cost is low. 本发明公开了一种乙烯利生产中有机废气处理方法及处理系统，将酯化重排工段产生的废气进行二级水洗得到第一废气，将其他工段产生的废气进行精馏，得到第二废气，将第一废气和第二废气混合后，进行二级碱洗得到混合废气，将混合气体进行深冷后，再导入
