Buried High Pour-Point Oil Pipeline Shutdown Temperature Drop Research Based on FLUENT

Abstract

When the buried high pour point oil pipeline is running, it is inevitable to avoid pipeline failures and the pipeline should be shutdown. After shutdown oil temperature dropped and viscosity increased, oil gelling happens, it will cause the accident "condensing tube". For high pour-point oil pipeline can start after shutdown, it should ensure the safety shutdown time of the pipeline and corresponding in the restart pressure. So it is necessary to guide the production practice and pipeline safe operation.
