Experimental Study on the Oil Pipeline Running with PPD Beneficiated for Zhanjiang-Maoming Oil Pipeline

This paper describes the experimental study on the oil pipeline running with PPD beneficiated for Zhanjiang-Maoming Oil Pipeline. The influence of quick temperature drop on the static stability of the oil with PPD beneficiated and anti-gelling the pipeline with PPD oil are examined. The results show that the heat exchange process with PPD beneficiated oil for Zhanjiang-Maoming Oil Pipeline can greatly ensure the heating treatment temperature and decrease condensation point to realize the safe intermittent transportation.
