Research On The New Technology And Equipment Of Oil Sludge Treatment

Oil sludge, the mixture of mud, sand and water polluted by oil and other organics, is the byproduct of the oil field production activities, which comes from the processes of crude oil collection and transportation. Because the hydrocarbon contained in the oil sludge is harmful to the environment, oil sludge is listed as a danger waste in the《the list of national danger waste》(HW08term).At present, there is a great amount of oil sludge produced in the course of oil field production. Therefore, the oil sludge discharge is one of the most important factors to affect the quality of local environment. Due to the stipulate of《The fee collection statute for the waste discharge》stated by State Department(No.39 order of the State Department), one ton oil sludge will cost￥1000 .If the oil sludge is discharged without any process, it will definitely be a serious economic load to the company. So an efficient and effective way to process the oil sludge is the urgent need for development of the oil-field company.In order to solve the problem, author cooperated with the technical department of Liaohe oil-field Company and did the relative research about the harm lessen process. Firstly, the paper researches on the present treatment of oil sludge in the worldwide scope. And it indicates that these methods could not meet the need including environment protection, high processing cost, the second time pollution, high complexion for industry realization. Secondly, we did a target research on the new technology and equipment, and did Experiment with the new technology and equipment in Liaohe oil-field Company. This can realize the oil mater caloric-recycle in the harm lessen process. Thirdly, the author analyzed the advanced nature, economic nature and social nature of the new technology and equipment.Base upon our research about the new technology and equipment, we can conclude that it not only can process the oil sludge completely, but also is able to effectively recycle the oil's caloric and clay contained in the oil sludge. So it has a prosperous developing foreground and strong practicability and maneuverability.
