adsorption

1. n. [Production Facilities, Enhanced Oil Recovery]
The property of some solids and liquids to attract a liquid or a gas to their surfaces. Some solids, such as activated charcoal or silica gel, are used as surfaces of adhesion to gather liquid hydrocarbons from a natural gas stream. To complete the process, the solids are treated with steam to recover the liquid hydrocarbons.
