Study Of Oil Refinery Waste Oil Resources

The effluent oil treatment in refineries is always a big problem which affects enterprises'environmental and economic benefit. At present, most of the effluent oil is saled as wastes after heating and dehydrating in the world. To solve the technical difficulties of the effluent oil treatment, according to the investigation of the references in the field of effluent oil treatment, flocculant and three-phase centrifuge and the situation of effluent oil treatment in Jinan Refinery, this paper analyzed the principle as well as using situation of flocculant and demulsifier by the test of three-phase centrifuge and determined the best operating condition.This paper analyzed different effects on different kinds of flocculant and adding quantity. The results showed that F04240SH and 500 ppm was the best flocculant and adding concentration, respectively.Effects of demulsifier and adding quantity were also conducted. OILBREAK(?) S 707 and 2000 ppm were found as the best demulsifier and adding concentration, respectively.The experiments of operating parameters of the three-phase centrifuge indicated that 260-270mm of diameter was the best operating condition.In addition, effects of temperature of ingredient were carried out.65-70 degrees centigrade was the best temperature for the three-phase centrifuge.According to the testing results, we determined the best flocculant and demulsifier, the right adding quantity, and the optimum operating parameters of the three-phase centrifuge. Lots of experiences on effluent oil treatment were obtained.The testing results illustrated that it was possible to treat effluent oil by three-phase centrifuge. According to the test, we got the information that the operating conditions were right and the process was easy to be controlled. The testing products conformed to the demand and satisfying results were obtained in Jinan Refinery.
