v: I. to take in and make part of an existing whole. 2. to recover liquid hydrocarbons from natural or refinery gas in a gas- absorption plant. The wet gas enters the absorber at the bottom and rises to die top, encountering a stream of absorption oil (a light oil) travelling downward over bubblecap trays, valve trays, or sieve trays. The light oil removes, or absorbs, the heavier liquid hydrocarbons from the wet gas. See bubble-cap tray, sieve tray, valve tray.

to fill part or all of the pore spaces.

n: (LPG) a mixture of heavier, gaseous, paraffinic hydrocarbons, principally butane and propane. These gases, easily liquefied at moderate pressure, may be transported as liquids and converted to gases on release of the pressure. Thus, liquefied petroleum gas is a portable source of thermal energy that finds wide application in areas where it is impractical to distribute natural gas. It is also used as a fuel for internal-combustion engines and has many industrial and domestic uses. Principal sources are natural and refinery gas, from which the liquefied petroleum gases are separated by fractionation.

n: (LRG) liquid propane or butane produced by a crude oil refinery. It may differ from LP gas in that propylene and butylene may be present.

abbr: liquefied refinery gas.

n: the gas produced from certain petroleum refinery operations (such as cracking or reforming). The composition of refinery gas varies in accordance with the process by which it is produced, but it consists essentially of the same paraffin hydrocarbons as natural gas plus olefins (propylene, ootylene, and ethylene) not found in natural gas.
