Abstract: When an oil product pipeline having great fall is operated with batch transportation process, viscosity change of contamination interface and elevation fall at turnover point make pipeline's throughput and inlet outlet pressure at pumping stations variable complicatedly.In the light of two fall control points at Gaozhuang-Yangquan pipeline section and Yangquan-Jinzhong pipeline section over ShiTai Oil Product Pipeline, hydraulic characteristics of the two sections are calculated under the condition of batch transportation process, inlet/outlet pressure variations are analyzed and pressure control programs for the fall control points are presented to ensure safety operation of pipeline and decrease contamination volume produced in batch transportation.
