Technological Reform of Pumping Station in Daqing-Tieling Oil Pipeline

The general process flow and problems existed in pumping stations of Daqing-Tieling oil pipeline before technological reform are introduced. On the basis of design principle of process flow, a process flow reform program on pumping stations is proposed, including simplifying the process flow with series pumps (to eliminate feed pump), with thermal medium exchanger and indirect heating system to substitute thesquare-box type heater. With these measures, the transportation process with the "first heater and second pump"way for the oil flow can be realized. The actual operation results indicate that the reformed process system has more advantages in operation, and the new process system supports the control center and pumping station control end to provide a real adjustment and protection to the whole pipeline system.
