DILUTING EXHAUST GAS BEING SUPPLIED TO BIOREACTOR

摘要

There is provided a process of growing a phototrophic biomass in a reaction zone. The reaction zone includes an operative reaction mixture. The operative reaction mixture includes the phototrophic biomass disposed in an aqueous medium. Gaseous exhaust material is produced with a gaseous exhaust material producing process, wherein the gaseous exhaust material includes carbon dioxide. Reaction zone feed material is supplied to the reaction zone of a photobioreactor such that any carbon dioxide of the reaction zone feed material is received by the phototrophic biomass so as to provide a carbon dioxide-enriched phototrophic biomass in the aqueous medium. A discharge of the gaseous exhaust material from the gaseous exhaust material producing process is supplied to the reaction zone feed material and defines a gaseous exhaust material reaction zone supply. A supplemental gaseous dilution agent is supplied to the reaction zone feed material. The carbon dioxide concentration of the supplemental gaseous dilution agent is less than the carbon dioxide concentration of the gaseous exhaust material reaction zone supply which is supplied to the reaction zone feed material. The carbon dioxide-enriched phototrophic biomass disposed in the aqueous medium is exposed to photosynthetically active light radiation so as to effect photosynthesis.
