Discussion on Floating/Wax Cleaning Transportation Process for Waxy Crude Oil

A floating/wax cleaning transportation process for waxy crude oil is proposed for the on-line oil pipeline with the throughput lower than design throughput in order to fully use the insulation effect of wax deposit to adjust oil and electricity consumption proportion. Based on the calculation of the insulation effect of wax deposit and the initial design of floating wax pig.the necessary conditions for floating/wax cleaning transportation process is given. In this paper, the safety of this process is analyzed. The authors consider that this process can effectively decrease the operational cost.
