The Industrial Experiment and Application of EP-W203 DRA in Sudan Oil Pipeline

The applied experiment of EP-W203 DRA in Sudan Oil Pipeline is made. The experiment on the one- point injection of DRA in No.1 Pumping Station is carried out first for drag reducing and throughput in- creasing between No.1 Pumping Station and No.3 Pumping Station, and then the between No.1 Pumping station No.2 Pumping Station for throughput increasing. The routine injection conduces after the experi- ments. The analysis on the variation of the physical behavior for different crude oils (resulting in high viscosity) is made. The analytical results show that this problem together with the rain season's factor make the crude oil's Reynolds number lower between No.2 Pumping Station and No.3 Pumping Station, which affects the effectiveness of DRA.
