However, a large amount of oily sludge is produced in the process of crude oil extraction and refinery sewage treatment. However, due to the different nature of the oily sludge produced by different operations, no process has been applied to the sludge treatment of all oil fields. At present, the methods for treating oily sludge at home and abroad generally include: incineration method, biological treatment method, hot washing method, solvent extraction method, chemical demulsification method, solid-liquid separation method, and the like.
