The factor of proportionality in the previous equations is called the Moody friction factor and is determined from the Moody resistance diagram shown in Figure…
A vent scrubber is a two-phase separator designed to remove the liquid from the relieving fluids before the gas is flared or vented. The liquid…
The maximum and minimum design temperatures for a vessel will determine the maximum allowable stress value permitted for the material to be used in the…
A weir system separator is a device that separates a mixture of oil, water, and gas into its individual components. It is commonly used in…
This process uses propylene carbonate as a physical solvent to remove CO2 and H2S. Propylene carbonate also removes C2+ hydrocarbons, COS, SO2, CS2, and H2O…
When subjected to a magnetic induction B, an elementary volume v of magnetizable substance acquires local magnetization M, where M is the magnetic moment of…
Flow regimes describe the nature of fluid flow. There are two basic flow regimes for flow of a single-phase fluid: laminar flow and turbulent flow.…
Specific gravity of a liquid is the ratio of the density of the liquid at 60°F to the density of pure water. API gravity is…
The most common form of parallel plate interceptor used in oil facilities is the corrugated plate interceptor (CPI). This is a refinement of the PPI…
The first form of a plate coalescer was the parallel plate interceptor (PPI). This involved installing a series of plates parallel to the longitudinal axis…
