管道式分离技术在渤西油气处理厂的性能试验

Performance Test of Pipe Separation Technology in Boxi Oil Gas Treatment Plant

油气水的分离是石油工业中一个重要的工艺流程,传统的分离罐体积大,质量大,造价昂贵。随着海上油田的逐步开发,降低成本成为石油生产关注的焦点。介绍了一种管道式油气分离新工艺及其试验结果。新型管道分离技术将油气水在管道中一边流动一边分离,达到油气水多相分离的目的。同传统的油气分离设备相比,具有占地面积小,分离效率高的特点。在渤西油气处理厂进行的工业现场试验表明,在试验参数范围内,新型管道分离器出口水中含油小于100 mg/L,出口油中含水率小于5%,达到了设计要求,取得了良好的效果。

Oil-water-gas separation in the petroleum industry is an important technological process. The conventional separators are bulky, heavy and expensive. In order to development offshore oil field, the petroleum industry toward focus on the compact separators that reduce production costs. Pipe separation technology is a new kind of separating method in oil-water-gas separation. It is low weight, low cost, efficient and convenient to maintain. This paper introduced this new compact separator, technological process and performance test. The test results show that the compact separator has good separating effect. When the water-cut inlet is from 50% to 60%, and the mixture flow rate is from 40 t/h to 100 t/h, the water-cut in oil outlet is less than 5%, and the oil-cut in water is less than 100ppm.
