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: a perforated steel tray on which bubble caps are mounted. Bubble caps and trays are arranged in bubble towers, cylindrical vessels set vertically. See sieve tray. valve tray.

n: a tray, installed in an absorber tower or fractionating column, that is similar to a bubble-cap tray, except that it has only holes but no bubble caps through it. This type of tray is more efficient than the bubblecap tray or the valve tray and less expensive than either;however, it does not operate properly over a wide range of flow rates.
