Typical industrial practice for dimethyl sulfoxide generation is to feed dimethyl sulfide,nitrogen dioxide and oxygen into the oxidation column for oxidation reaction.This paper introduces the simulated calculation method and process of ASPEN PLUS process simulation software,and analyzes the influence of oxygen amount and oxidation temperature(the temperature in the reaction area of oxidation column)on the oxidation process,puts forward the optimal oxygen injection amount,verifies the optimal oxidation temperature,and calculates the cooling capacity needed in the process.Combined with the actual parameters of a certain project,it is shown that this process simulated calculation method is reliable and can be used to guide industrial production.
