There is provided a process for effecting growth of phototrophic biomass within the reaction zone of a photobioreactor, comprising, after effecting at least a reduction in the molar rate of supply of carbon dioxide to the reaction zone of the photobioreactor, supplying a gaseous photobioreactor exhaust, that includes diatomic (or molecular) oxygen being generated by photosynthesis effected within the reaction zone by the supplied carbon dioxide, to a combustion zone of a combustor.
摘要:
A process of growing a phototrophic biomass in a reaction zone, including a reaction mixture that is operative for effecting photosynthesis upon exposure to photosynthetically active light radiation, is provided. The reaction mixture includes phototrophic biomass that is operative for growth within the reaction zone. In one aspect, the carbon dioxide supply is modulated in response to detected process parameters. In another aspect, inputs to the reaction zone are modulated based on changes to the carbon dioxide supply. In another aspect, dilution of the carbon dioxide-comprising supply is effected. In another aspect, pressure of the carbon dioxide-comprising supply is increased. In another aspect, water is condensed from the carbon dioxide-comprising supply and recovered for re-use. In another aspect, the produced phototrophic biomass is harvested at a rate which approximates a predetermined mass growth rate of the phototrophic biomass.

A process of growing a phototrophic biomass in a reaction zone is provided. Gaseous exhaust material is produced with a gaseous exhaust material producing process. At least a fraction of the gaseous exhaust material is supplied to a reaction zone feed material which reaction zone feed material is supplied to the reaction zone of a photobioreactor at a pressure which effects flow of the reaction zone feed material through at least a seventy (70) inch vertical extent of the aqueous medium.

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. The carbon dioxide-enriched phototrophic biomass disposed in the aqueous medium is exposed to photosynthetically active light radiation so as to effect photosynthesis. A discharge of the gaseous exhaust material from the gaseous exhaust material producing process is modulated based on sensing of at least one reaction zone parameter. The modulating of the discharge of the gaseous exhaust material includes modulating of a supply of the discharged gaseous exhaust material to the reaction zone feed material, wherein the discharged gaseous exhaust material which is supplied to the reaction zone feed material defines a gaseous exhaust material reaction zone supply, wherein the gaseous exhaust material reaction zone supply includes carbon dioxide.

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 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.
