A name applied to fractionators, particularly those separating isomers; i.e., butane splitter refers to a deisobutanizer.
An absorbent for recovering vapors of a lighter absorbent that is used in the main absorption process of a gas processing plant.
The unit where the gas is processed with an absorbant (normally light oil) to remove light hydrocarbons from the gas stream.
Condensate that has been stabilized to a definite vapor pressure in a fractionation system.
A name for a fractionation system that reduces the vapor pressure of a liquid product so that the resulting liquid is less volatile.
The vertical chimney-like installation that is the waste disposal system for unwanted vapor such as flue gases or tail-gas streams.
The system of separators wherein the liquid portion of the well effluent is separated from formation gas and flash vapors.
This refers to a gas volume measurement at a specified temperature and pressure. The temperature and pressure may be defined in the gas sales contract or by reference to other standards. Typically the standard pressure and temperature are 14.7 psia and 60 F.
A term used to relate a volume of vapor at specified conditions in U.S. customary units.
A term used to relate a volume of vapor at specified conditions in metric units.
This law is specific for each of several states. The law defines the pressure and temperature bases under which a standard cubic foot of gas should be measured in the particular state. The standard applies only to the specific state and may not agree with that in another state.
One of the names given to a boiler plant.
Steam with a minimum amount of superheat to prevent condensation.
Steam that exists at the temperature corresponding to its absolute pressure. Saturated steam may contain, or be free of, water particles.
The name given to the column wherein the absorbed product is distilled from the lean absorption oil. In plants using a low molecular weight absorption oil, the still is designed as a fractionation unit. In plants using a high molecular weight absorption oil, the still may use steam or other fluids as a stripping medium.
