Abstract:For relieve the pressure of Full-load operation in an import oil pipeline, and improve the ability of dealing with emergency condition, an industry experiment of drag reduction agent(DRA) application has been done. By adding the EP DRA In the pump station to reduce the pipeline operation pressure, and increase the line throughput. The result show that 10ppm DRA addition could increase the oil throughout by 14%. On the base of industrial operating test, DRA is applied in industry. In the case of 10ppm DRA addition,the pipeline throughout could increase by 15% with constant pressure,while the friction loss could decrease by 16% with constant pipeline throughout.. The result proved that the DRA could not only increase pipeline capacity, but also reduce friction, which reduce the pressure and risk of pipeline operation and improve the ability of dealing with emergency condition.
