Photobioreactor systems and methods for treating CO 2 -enriched gas and producing biomass
First Claim
1. A photobioreactor system comprising:
- a plurality of interconnectable photobioreactor sections which, when connected together, form at least one longitudinally-oriented photobioreactor unit of the photobioreactor system, the photobioreactor sections each comprising a liquid flow channel defined within a base and a light-transparent cover that forms a gas headspace between the cover and the liquid flow channel;
whereinthe cover is constructed and arranged to cover at least a substantial portion of the liquid flow channel and is configured to be separable from the base and capable of providing the gas headspace even when a gas pressure within the photobioreactor unit is less than the atmospheric pressure surrounding the photobioreactor section.

Abstract
Certain embodiments and aspects of the invention relate to a photobioreactor including covered photobioreactor units through which a liquid medium stream and a gas stream flow. The liquid medium comprises at least one species of phototrophic organism therein. Certain methods of using the photobioreactor system as part of fuel generation system and/or a gas-treatment process or system at least partially remove certain undesirable pollutants from a gas stream. In certain embodiments, a portion of the liquid medium is diverted from a photobioreactor unit and reintroduced upstream of the diversion position. In certain embodiments, the disclosed photobioreactor system, methods of using such systems, and/or gas treatment apparatus and methods provided herein can be used as part of an integrated combustion method and system, wherein photosynthetic organisms used within the photobioreactor are harvested from the photobioreactor, processed, and used as a fuel source for a combustion system like an electric power plant.
