Title (EN) CO2 CAPTURE WITH CARBONIC ANHYDRASE AND TERTIARY AMINO SOLVENTS FOR ENHANCED FLUX RATIO
(FR) CAPTURE DE CO2 À L'AIDE D'UNE ANHYDRASE CARBONIQUE ET DE SOLVANTS AMINO TERTIAIRES POUR UN RAPPORT DE FLUX AMÉLIORÉ
Abstract:
(EN) Techniques for treating CO2 containing gas include contacting the gas with an aqueous absorption solution including carbonic anhydrase as well as an absorption compound, which may be a tertiary amino compound for enzymatically enhanced flux of CO2. The absorption compound may include MDEA, TEA, DEMEA, DMMEA, TIPA or DMgly, for example. The techniques may provide concentrations to enhance the enzymatic catalysis and inhibit viscosifying of the absorption solution or enzyme denaturing that would lower the overall CO2 absorption rate. The absorption may be conducted at a temperature between about 0° C and about 80 °C, for example. Processes, uses and formulations are provided for enhanced CO2 capture.
(FR) Les techniques destinées à traiter un gaz contenant du CO2 ci-décrites comprennent la mise en contact du gaz avec une solution d'absorption aqueuse contenant une anhydrase carbonique ainsi qu'un composé d'absorption, qui peut être un composé amino tertiaire pour obtenir un flux de CO2 amélioré par l'enzyme. Le composé d'absorption peut comprendre une MDEA, TEA, DEMEA, DMMEA, TIPA ou DMgly, par exemple. Les techniques selon l'invention peuvent fournir des concentrations pour améliorer la catalyse enzymatique et inhiber la viscosification de la solution d'absorption ou la dénaturation de l'enzyme qui abaisserait le taux d'absorption global du CO2. L'absorption peut être mise en œuvre à une température comprise entre environ 0 et environ 80°C, par exemple. Des procédés, des utilisations et des formulations pour une capture améliorée du CO2 sont également décrits.
