Absorption (chemistry) - encyclopedia article - Citizendium

In chemistry, absorption is a process by which a substance incorporated in one state is transferred into another substance of a different state (e.g., gases being absorbed by a liquid or liquids being absorbed by a solid).As an industrial process, the most commonly encountered use of absorption is for the separation and/or purifiion of a gas mixture by the absorption of part of the mixture

Gas properties - PetroWiki

The partial pressure of a gas in a mixture of gases is defined as the pressure that the gas would exert if it alone were present at the same temperature and volume as the mixture. Dalton’s law states that the sum of the partial pressures of the gases in a mixture is equal to the total pressure of the mixture.

The 100% ETO sterilizers using unit-dose cartridges eliminate the need for external tanks.

Merane Properties - Physical

If the gases in a mixture do not interact strongly with the merane material, the pure gas intrinsic selectivity and the gas mixture selectivity will be equal. This is usually the case for mixtures of O 2 and N 2. Gas mixtures are also usually non-ideal, especially under high pressure, and thus the actual selectivity may be quite different
