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.

the wash oil used to remove heavier hydrocarbons from the gas stream.

a vessel that receives and temporarily stores a liquid used in the feed stock or the processing of a feed stream in a gas plant or other processing facility.

n: the expansion of a gas, vapour, or liquid stream from a higher pressure to a lower pressure with no change in enthalpy of the stream.

n: a large, sloping sedimentary deposit at the mouth of a canyon, laid down by intermittently flowing water, especially in arid climates, and composed of gravel and sand. The deposit tends to be coarse and unworked, with angular, poorly sorted grains in thin, overlapping sheets. A line of fans may eventually coalesce into an apron that grows broader and higher as the slopes above are eroded away.

land counterpart of a river delta. Characteristic of sediments that have been transported by a fast moving stream then dropped out of the flow as the stream velocity drops as it spreads out. Typical of zones of heavy water runoff such as found at the base

n: any of several compounds employed in treating natural gas. Amines are generally used to remove hydrogen sulphide from water solutions and carbon dioxide from gas or liquid streams.

a tool to enlarge a drilled hole.

n: 1. the pressure maintained on equipment or systems through which a fluid flows 2. in reference to engines, a term used to describe the resistance to the flowof exhaust gas through the exhaust pipe. 3. the operating pressure level measured downstream from a measuring device4.
