Two common internals not discussed are coalescing plates and sand jets. It is possible to use various plate or pipe coalescer designs to aid in…
For distillation services, as in condensate stabilization, tray design is well understood, and many engineers are more comfortable with trays than with packing. In the…
Most oil-treating equipment relies on gravity to separate water droplets from the oil continuous phase, because water droplets are heavier than the volume of oil…
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…
In vertical separators, a minimum diameter must be maintained to allow liquid drops to separate from the vertically moving gas. The liquid retention time requirement…
A pipe that releases gas to disperse into the atmosphere is called a vent. If the gas is burned at the tip, it is called…
Plate coalescers are skim tanks or vessels that use internal plates to improve the gravity separation process. Various configurations of plate coalescers have been devised.…
These processes are based on the solubility of the H2S and/or CO2 within the solvent, instead of on chemical reactions between the acid gas and…
The molecular weight of the stream is calculated from the weighted average gas molecular weight given by: The molecular weight of the gas stream of…
There are usually two naphtha cuts produced from most crude. These are: Light naphtha (sometimes called light gasoline) Heavy naphtha. Both these streams are the…
