Abstract: Aiming at the problem of non-methane total hydrocarbon content and the ethylene oxide content in the carbon dioxide emission gas of the ethylene oxide/ glycol plant exceeding the new national standard, several solutions were proposed and compared. Combining with the actual situation of the ethylene oxide/ glycol plant, the catalytic oxygen treatment scheme with low investment, low energy consumption and small floor space was finally selected. This paper elaborated on the scheme. After actual operation, the scheme was proved to be feasible, and it is of reference significance for treating the same tail gas.
