A

Device used to absorb some elements of a gas mix.

1- Property of solids and liquids to retain certain substances (gases or liquids) entirely.
2- Separation process of a gas mix from some of its elements by selective dissolution into a solvent.

French agency for environment and energy management (Agence De l’Environnement et de la Maîtrise de l’Energie).

Surface phenomenon by which gas or liquid molecules hold on to the solid outer layer of adsorbents by various processes. Clays and zeolites for instance are good natural adsorbents, as is active coal.

French national agency for research (Agence Nationale de la Recherche).

Resulting from the intervention of humans.

Transformation of a gas into a solid.

Liquid, gas or plasma carrying water molecules (H2O).

Waterproof geological formation holding water. The most superficial aquifers contain freshwater that is used for food and as drinking water. Deeper underground, the water found in aquifers is so salty that it is totally unfit for human consumption. They are called deep saline aquifers. In some cases, aquifers host oilfields or gas fields when the water in the intergranular space of the rock is replaced by hydrocarbons. They can also hide natural deposits of pure carbon dioxide. This inspired the idea to store CO2 in the pores of the rocks as mitigation measure.
