[0002] About 55% of the production of propylene oxide in my country adopts the chlorohydrin method. The chlorohydrin method uses propylene and chlorine gas as raw materials. After three steps of propylene chlorohydrinization, lime milk saponification, and product purification, qualified products are finally obtained. Waste gas cannot be avoided during purification and refining, and due to the low boiling point of propylene oxide, some propylene oxide gas will be discharged with the waste gas, and it is easy to burn at room temperature, and it will be discharged directly without treatment, which will not only pollute the environment, but also There is a big security risk
