Research progress on resource treatment and utilization of oily sludge
Introduce the composition and pollution hazards of oily sludge.This article briefly describes the sources and characteristics of three types of oil sludge with high content,including tank bottom sludge,floor sludge,and refinery sludge.This paper mainly analyzes the technological principles of the traditional hot technologies of oily sludge resource treatment,such as pyrolysis,surfactant,reinjection profile control,lotion,etc.,as well as the advantages and limitations of the relevant processes and the application status at home and abroad.Explored two emerging technologies for treating oil sludge,namely microwave radia-tion and ultrasonic treatment,with the aim of providing reference suggestions for the resource utilization of oily sludge.
