Contaminated Products Cut and Blending of Zhenhai Refinery—Hangzhou Kangqiao Products Pipeline

Zhenhai Refinery—Hangzhou Kangqiao Products Pipeline, with a total length of 158. 5 km, 355.6×7.1 mm, 6.27 MPa between Zhenhai Initial Station-Shangyu and 2.5 MPa between Shangyu-Xiaoshan, transports ^#93 gasoline, ^#90 gasoline, ^#0 diesel and ^#3 jet fuel. The transportation succession is ^#93 gasoline → ^#90 gasoline → ^#0 diesel → ^#3 jet fuel → ^#0 diesel → ^#90 gasoline → ^#93 gasoline. The problems on the contaminated products cut and treatment during the batch transportation are analyzed in detail. To further increase transportation efficiency of the pipeline, the blending method is adopted. For the problems about contaminated products cut and blending produced during the pipeline operation, some effective measures are given.
