Several Design Features on Sudan Oil Pipeline

The total length of Sudan crude oil pipline is 1504.1 km, the design pressure of trunk line is 9.7 MPa, and that of the crossing pipeline (at Nile River and Atbala River) is 14.8 MPa.There are 6 pump stations and 16 intermediate valve chambers respectively installed along the line, not including the Port Sudan terminal.The design output of the pipeline at first stage is 40×10⁴m³/d, and that is 24×10⁴m³/d at second stage.The design features of the pipeline includs that the transportation process is tight line transportation, and double treatments of crude oil with pour point depressant have been carried out before it is transported; 3 kinds of overpressure protection systems are installed in 6 pump stations, which can provide an effective protection to pump sets; the back-pressure valves are installed in Port Sudan, which can prevent the pipeline from slack flow; and 2 screw pump sets are respectively installed in 6 pump stations in order to prevent the pipeline from jelling.
