For an emulsion to exist there must be two mutually immiscible liquids, an emulsifying agent, and sufficient agitation to disperse the discontinuous phase into the…
Back-pressure can affect either the set pressure or the capacity of a relief valve. The set pressure is the pressure at which the relief valve…
The specific gravity difference between the dispersed water droplets and the oil should result in the water “sinking” to the bottom of the treatment vessel.…
A double-pipe exchanger is made up of one pipe containing the tube fluid concentric with another pipe, which serves as the shell. The tube is…
The factor of proportionality in the previous equations is called theĀ Moody friction factor and is determined from the Moody resistance diagram shown in Figure…
One method of assuring that hydrates do not form is to assure that the amount of water vapor in the gas is always less than…
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…
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…
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…
For an oil and gas separator to accomplish its primary functions, pressure must be maintained in the separator so that the liquid and gas can…
