Scenario Comparison and Selection on Shut down and Restart Technology for Renqiu-Beijing Oil Pipeline

Three technical scenarios of shut down and restart for Renqiu-Beijing Oil Pipeline are compared, including the oil heating methods, and the direct heating method is considered as the best one. On the basis of comparison results, the optimal scenario, the forward and reverse pumping heating transportation technology, are selected, which can provide a technical support to transport oil to Renqiu Oil Refinery with a capacity of 50×10⁴ t/a.
