Study on the Transportation Process for PPD-treated Sudanese Blend Crude Oil at Constant Temperature

In this paper, the technology for transporting PPD-treated Sudanese blend crude oil at constant temperature, the process of which consists of the development of PPD-treated available for Sudanese blend oil and simulation for the rheological properties of the blend oil as well as the simulation for the wax deposition of the blend oil in the Sudan pipeline, are studied. Based on the conclusions for the study and the experiences of applying PPD on some pipelines before, the technology called "comprehensively treating crude oil with PPD" is applied on the Sudan pipeline successfully, which saves a great deal of capital investment in pipeline construction stage and decrease enomous fuel consumption in later operation stage. The Sudan Pipeline has benefited or heen benefiting a lot from the study.
