Recovering off-gas from photobioreactor
First Claim
Patent Images
1. A process for effecting growth of phototrophic biomass within a reaction zone of a photobioreactor, comprising:
- generating carbon dioxide-comprising gaseous exhaust material from a carbon dioxide-comprising gaseous exhaust material producing process;
supplying the carbon dioxide-comprising gaseous exhaust material to the reaction zone of a photobioreactor such that carbon dioxide is thereby supplied to the reaction zone;
producing a gaseous headspace material within a headspace of the photobioreactor with gaseous photobioreactor exhaust produced by photosynthesis within the reaction zone; and
after at least reducing the rate of supply of carbon dioxide to the reaction zone of the photobioreactor;
(i) discharging at least a fraction of the gaseous headspace material to a space other than that of a combustion zone of a combustor, wherein the discharging effects a reduction in the molar concentration of carbon dioxide of the gaseous headspace material, such that the gaseous headspace material becomes of a quality that is suitable for effecting combustion of a fuel within the combustion zone of a combustor; and
(ii) after the discharging in (i), discharging the gaseous photobioreactor exhaust to the combustion zone of the combustor.

Abstract
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.
