摘要：This paper introduces the organic waste gas treatment technology such as adsorption method, thermal damage method, liquid absorption method, condensation method, biofilm method and cold plasma method, and analyzes its characteristics and its application. According to the tail gas composition and concentration characteristics of coke oven gas-based methanol project, by comparing the organic waste gas treatment technology and the actual situation of the company, and according to the calculated material and energy value, the process design scheme of ＂6 RTO parallel combustion ＋ waste heat recovery system ＋ desulfurization tower with quench cooler＂ is determined. Through reasonable equipment selection and material selection, match with the system pressure and temperature, so that the system is under safe operation and can meet the requirements of discharge standards at the same time.
