Title (EN) PRODUCTION OF ALGAE USING CO2-CONTAINING GAS
(FR) PRODUCTION D'ALGUES À L'AIDE D'UN GAZ CONTENANT DU CO2
Abstract:
(EN) The invention is directed to a method for using a gaseous feed stream comprising CO2 as a feed stream for growing algae, said method comprising a) contacting said gaseous feed stream with an absorption liquid comprising carbonic anhydrase in an absorption module to produce a lean gas stream and a liquid feed stream comprising bicarbonate; b) contacting part of the liquid feed stream and/or part of the gaseous feed stream comprising CO2 with microorganisms to generate carbonic anhydrase and c) contacting part of the liquid feed stream with an algae culture to produce algae-containing biomass. Another aspect of the invention is directed to an apparatus for sequestration of CO2 by using algae, said apparatus comprising two coupled circulation systems that each comprise at least one bioreactor.
(FR) L'invention concerne un procédé permettant d'utiliser un courant d'alimentation gazeux comprenant du CO2 en tant que courant d'alimentation pour faire pousser des algues, ledit procédé consistant à a) mettre en contact ledit courant d'alimentation gazeux avec un liquide d'absorption comprenant de l'anhydrase carbonique dans un module d'absorption pour produire un courant gazeux pauvre et un courant d'alimentation liquide comprenant du bicarbonate; b) mettre en contact une partie du courant d'alimentation liquide et/ou une partie du courant d'alimentation gazeux comprenant le CO2 avec des micro-organismes pour générer de l'anhydrase carbonique, et c) mettre en contact une partie du courant d'alimentation liquide avec une culture d'algues pour produire une biomasse contenant des algues. Un autre aspect de l'invention concerne un appareil de séquestration du CO2 à l'aide d'algues, ledit appareil comprenant deux systèmes de circulation couplés qui comportent chacun au moins un bioréacteur.
