Controlled system for supporting algae growth with adsorbed carbon dioxide
First Claim
1. A system for capturing carbon in a carbon-poor media to create a carbon-enriched media thereof, for assimilation of the carbon captured by the enriched media into an algae biomass, the system comprising:
- a reactor for growing algae biomass in the media, wherein the reactor has an input port and an output port;
an absorber having a plurality of panels, wherein each panel has a surface area, and wherein the absorber has a first input port, a second input port, a first output port and a second output port;
a source of combustion gases with a conduit for directing the combustion gases into the absorber through the first input port of the absorber;
a pump for establishing a volumetric flow rate of carbon-poor media from the output port of the reactor and into the second input port of the absorber, wherein the carbon-poor growth media is presented on panel surface areas in the absorber for a counter current flow interaction with the combustion gases to create the carbon-enriched growth media for discharge from the first output port of the absorber and into the reactor through the input port of the reactor;
a first sensor for measuring a first carbon concentration level, C1(measured), in the reactor at the output port of the reactor;
a second sensor for measuring a second carbon concentration level, C2(measured), of media discharged from the first output port of the absorber; and
a controller for operating the pump with input from the first and second sensors to establish an optimized assimilation of captured carbon from the carbon-enriched growth media into the algae biomass in the reactor.

Abstract
A system and method for creating a useful carbon-enriched media in a reactor which will assimilate carbon into an algae biomass, requires measuring a respective carbon concentration of the media, C(measured), as it enters, and as it leaves the reactor. Operationally, desired carbon concentration values are preset, C(set), and are provided along with values obtained for C(measured) as input to a system controller. Respective differentials between C(measured) and C(set) at the reactor'"'"'s input and output ports are determined by the controller and are used to control a volumetric fluid flow rate of the media through the reactor. Specifically, the controller establishes a volumetric fluid flow rate of the media as it is passed through an absorber where the media is carbon-enriched by interaction with combustion gases from an external source (e.g. a power plant).
