n: see hydrogen embrinlement.

n: Metal becomes brittle rupture because of absorbing hydrogen.

low ductility of a metal due to its adsorption of hydrogen. More commonly called hydrogen embrittlement.

a highly porous solid, usually a charcoal. Used for adsorption of unwanted materials.

n: the adhesion of a thin film of a gas or liquid to the surface of a solid. Liquid hydrocarbons are recovered from natural gas by passing the gas through activated charcoal, silica gel, or other solids, which extract the heavier hydrocarbons. Steam treatment of the solid removes the adsorbed hydrocarbons, which are then collected and re-condensed. The adsorption process is also used to remove water vapour from air or natural gas. Compare absorption.

n: A surface phenomenon exhibited by a solid (adsorbent) to hold or concentrate gases, liquids or dissolved substances(adsorptive) upon its surface, due to adhesion.

the attraction and holding of a layer of a chemical on the wall of a formation. Usually held by ionic charge or wetting preference.

the range of wavelength energy that can be adsorbed by a given formation.

n: The number of treating chemical of drilling fluid that the adsorbent can adsorb when the adsorption is under balance.

n: a plant that processes natural gas with an adsorbent.

n: The number of treating chemical of drilling fluid that the adsorbent can adsorb when the adsorption is under balance.
