Title
(EN) A REVERSIBLE LIGHT DRIVEN GAS ABSORBENT SOLUTION AND PROCESS
(FR) SOLUTION ET PROCÉDÉ D'ABSORPTION DE GAZ RÉVERSIBLE ENTRAÎNÉE PAR LA LUMIÈRE
Abstract
(EN)
The invention relates to a process for removing a target gas from a gas stream rich in the target gas and to an absorbent solution for absorbing a gas, such as carbon dioxide, from a gas stream. The invention involves the use of a photoactive compound that is convertible from a first state to a second state upon irradiation to facilitate removal or collection of a target gas from a gas stream.
(FR)
La présente invention concerne un procédé permettant d'éliminer un gaz cible d'un flux gazeux riche en gaz cible et une solution absorbante permettant d'absorber un gaz, tel que du dioxyde de carbone, d'un flux gazeux. L'invention fait intervenir l'utilisation d'un composé photoactif qui peut être converti d'un premier état vers un second état après exposition à un rayonnement pour faciliter l'élimination ou la collecte d'un gaz cible à partir d'un flux gazeux.
