- W3131188197 abstract "Ethylene spent caustic with strong alkalinity, high chemical oxygen demand (COD) and toxicity could not be directly discharged without pretreatment. In this paper, the composition of spent caustic from a petrochemical enterprise was analyzed. Effects of oxidants, reaction temperature, pressure and residence time on the removal ratio of COD in the spent caustic were investigated. The oxidation reaction mechanism of main organic sulphides in the spent caustic was discussed. Results show that COD of the ethylene spent caustic is ∼ 24.5 g/L, the main compositions are S2- and disulphides including a small amount of ketones and phenolic organics. The removal ratio of S2- in spent caustic is up to 100%, and the removal ratio of COD is over 83% at 180 °C with the pressure of 2 MPa and residence time of 15 min using oxygen as an oxidant. Taking dimethyl disulphide as an example, dimethyl disulphide with HO• firstly produces methyl thiosulphonate and methyl sulphenic acid, then further oxidized to generate methanesulphonic acid, and the C-S bonds in the methanesulphonic acid were broken to generate sulphuric acid and formic acid. So the oxidative degradation products of organic sulphides are sulphuric acid, formic acid and a small amount of acetic acid." @default.
