A pipeline 150 miles long from Beaumont pump station to a tank farm at Glendale is used to transport Alaskan North Slope crude oil (ANS crude). The pipe is 20….
In Problem 5.13.1, what throughputs can be achieved when pumping gasoline alone?
In Problem 5.13.1, what throughputs can be achieved when pumping gasoline alone? Use a specific gravity of 0.74 and viscosity of 0.65 for gasoline at the flowing temperature. Compare the pump head requirements when pumping diesel versus gasoline. Use the Hazen-Williams equation with a Cfactor of 145.
A pipeline 50 miles long, 16 in. outside diameter, 0.250 in. wall thickness is constructed of API 5LX-65 material. It is used to transport diesel and other refined products from the refinery at Carson to a storage tank at Compton. During phase I, a flow rate of 5000 bbl/hr of diesel fuel is to be transported with one pump station located at Carson. The required delivery pressure at Compton is 50 psi. Assume a generally rolling pipeline elevation profile without any critical peaks along the pipeline. The elevation at Carson is 100 ft, and the storage tank at Compton is located on top of a hill at an elevation of 350 ft.
(a) Using diesel with specific gravity of 0.85 and a viscosity of 5.5 cSt at a flowing temperature of 70°F, calculate the total pressure required at Carson to transport 5000 bbl/hr of diesel on a continuous basis. Use the Hazen-Williams equation with a C-factor of 125. The Carson pump suction pressure is 30 psi and the pump is driven by a constant-speed electric motor.
(b) Determine the BHP and motor HP required at Carson assuming 82% pump efficiency and 96% motor efficiency.
(c) What size electric motor would be required at Carson?
(d) Assuming a maximum allowable operating pressure of 1400 psi for the pipeline, how much additional throughput can be achieved in phase II if the pumps are modified at Carson?
