Diluting exhaust gas being supplied to bioreactor
First Claim
1. A process of growing a phototrophic biomass in a reaction zone, wherein the reaction zone includes an operative reaction mixture, wherein the operative reaction mixture includes the phototrophic biomass disposed in an aqueous medium, comprising:
- producing gaseous exhaust material with a gaseous exhaust material producing process, wherein the gaseous exhaust material includes carbon dioxide;
supplying a supplemental gaseous dilution agent to the gaseous exhaust material to produce a diluted gaseous exhaust material, wherein the supplemental gaseous dilution agent has a carbon dioxide concentration that is less than the carbon dioxide concentration of the gaseous exhaust material and wherein the supplying of the supplemental gaseous dilution agent to the gaseous exhaust material is effected in response to sensing of a carbon dioxide concentration in the gaseous exhaust material being discharged from the carbon dioxide producing process which is greater than a predetermined maximum carbon dioxide concentration value;
supplying the diluted gaseous exhaust material to the reaction zone such that carbon dioxide is received by the phototrophic biomass so as to provide a carbon dioxide-enriched phototrophic biomass in the aqueous medium; and
exposing the carbon dioxide-enriched phototrophic biomass disposed in the aqueous medium to photosynthetically active light radiation so as to effect photosynthesis.

Abstract
There is provided a process of growing a phototrophic biomass in a reaction zone. Prior to supplying a reaction zone feed material, including gaseous exhaust from a gaseous exhaust material producing process, supplying the reaction zone feed material with a supplemental gaseous dilution agent, wherein the carbon dioxide concentration of the supplemental gaseous dilution agent is less than the carbon dioxide concentration of the gaseous exhaust material which is supplied to the reaction zone feed material.
