A Study on the Low Throughput Transportation of Oil Treated with PPD in Honghu——Jingmen Oil Pipeline

In the light of low throughput, unstable pressure and more kinds of oils, heating and PPD treated transportation technology are applied in Honghu--Jingmen oil pipeline. By means of laboratory evaluation and operation analysis, the modified result of CE PPD to Xi Jiang oil and Changqing oil have been dis- cussed, the initial setting during operating has been described and the corresponding improvements to CE PPD have been put forward.
