TL;DR: In this article, a two-stage wet air oxidation method was employed to treat oily sludge to remove 931% oil from the oil sludge and reduce the volume of sludge by 854%.
Abstract: Oily sludge produced in petrochemical industries contains a large amount of toxic and hazardous substances High oil sludge yield and high treatment cost have become major obstacles to the development of the petrochemical industry In this study, the treatment and disposal of oily sludge using the wet oxidation method was investigated Firstly, the orthogonal optimization experiment was designed to discuss the influence of reaction time, reaction temperature, oxidant amount, and emulsion splitter amount on the removal efficiency of oil and sludge volume On this basis, a two-stage wet air oxidation method was employed to treat oily sludge The results show that the two-stage oxidation method could remove 931% oil from the oil sludge and reduce the volume of oil sludge by 854% Furthermore, the oil sludge treated with wet oxidation could be more easily separated from water, and the waste oil could be recycled The proposed two-stage wet oxidation method shows excellent performance in treating oily sludge, from which resources can be recycled while reducing the amount of sludge
