Re-entrainment is a phenomenon caused by high gas velocity at the gas-liquid interface of a separator. Momentum transfer from the gas to the liquid causes…
The purpose of the gas separation section of the vessel is to condition the gas for final polishing by the mist extractor. From field experience…
In the gravity settling section the liquid drops will settle at a velocity determined by equating the gravity force on the drop with the drag…
Tube holes cannot be drilled very close together, since this may structually weaken the tube sheet. The shortest distance between two adjacent tube holes is…
Heat-exchanger tubes should not be confused with steel pipe or other types of pipe that are extruded to steel pipe sizes. The outside diameter of…
Shell-and-tube exchangers contain several types of baffles to help direct the flow of both tube-side and shell-side fluids. Pass partition baffles force the fluid to…
Shell-and-tube heat exchangers are cylindrical in shape, consisting of a bundle of parallel tubes surrounded by an outer casing (shell). Both the tube bundle and…
The sensible heat duty for the oil phase is: where Q0 = oil flow rate, bpd SG = oil specific gravity C0 = oil specific…
Federal regulations and most authorities having jurisdiction require that “free oil” be removed from deck drainage prior to disposal. It is extremely difficult to predict…
In every system substances that show up as “oil” in the laboratory test procedure will be dissolved in the water. This is especially true where…
