The Study On Incineration Technology And Integrated Utilization Of Oil-sand In Shengli Oilfield

Oil-sand, 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-sand is harmful to the environment, oil-sand is listed as a dander waste in the 《the list of national danger waste 》 (HW08term). At present, there is a great amount of oil-sand produced in the course of oil field production. According to the statistics, the yield of oil-sand in the Shengli oil-field is about 110000 ton every year. Therefore, the oil-sand 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-sand will cost ￥1000 . If the oil-sand 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-sand is the urgent need for development of the oil-field company.In order to solve the problem, author cooperated with the technical department of Shengli oil-field Company and did the relative research about the harm lessen process. Firstly, the paper researches on the present treatment of oil-sand 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 ingredients of the solidification, and work out an new kind solidification, which not only can solid the oil-sand, but also can make it well-burnt. Furthermore, that can not effect the burning efficiency. Based on this procedure, we present the new technology as followed. After solidification treatment, make the oil-sand to a coal-like fuel, and put it in the coal fuel to use it as the fuel to the coal burning boiler. This can realize the oil mater caloric-recycle in the harm lessen process. Thirdly, we use the technology in the industrialization, and put forward a more reasonable solidification burning program. Finally, according to the result of the environment inspection, every...
