| 20110287526 | PROCESS FOR GROWING BIOMASS BY MODULATING INPUTS TO REACTION ZONE BASED ON CHANGES TO EXHAUST SUPPLY - 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 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. The carbon dioxide-enriched phototrophic biomass disposed in the aqueous medium is exposed to photosynthetically active light radiation so as to effect photosynthesis. When an indication of a change in the molar rate of supply of carbon dioxide in the gaseous exhaust material reaction zone supply to the reaction zone feed material is sensed, at least one input to the reaction zone is modulated. The modulating of at least one input includes at least one of: (a) effecting or eliminating supply of, or modulating the intensity of, the photosynthetically active light radiation to which at least a fraction of the carbon dioxide-enriched phototrophic biomass is exposed, and (b) effecting, modulating, or eliminating the molar rate of supply, or commencing supply, of a nutrient supply to the reaction zone. | 11-24-2011 |
