Study on Vacuum Degree of Mechanical Cleaning System for Product Oil Tank

Abstract:

A practical calculation method to determine the vacuum degree of a mechanical cleaning system is proposed mainly based on the theories of fluid mechanics. The system for cleaning of product oil tanks is operated relying on vacuum suction and simplified without heating section comparing with the system for crude oil tanks. It shows that the determination of vacuum level depends on two factors: to overcome the frictional resistance of suction tank's inlet pipes and to meet the net positive suction head (NPSH) required for a centrifugal pump fixed on outlet pipes of a suction tank. So, the higher and lower limits of vacuum degree can be found. The calculating method of vacuum degree is proved in a real system.
