Abstract: A method includes containing an algae media within a contactor, introducing a stream of natural gas comprising up to 80 wt % carbon dioxide (CO2) into the contactor, contacting the natural gas on the algae media and thereby allowing the algae media to consume CO2 from the natural gas, and discharging a stream of natural gas comprising 2 wt % or less CO2 from the contactor.

Abstract: A system for growing algae for biofuel production includes a bioreactor configured to contain an algae slurry, an algae-water separator fluidly coupled to the bioreactor to receive and separate the algae slurry into algae and separated water, and an organics treatment system that receives a portion of the separated water and is configured to reduce a concentration of organics in the portion of the separated water. A recycle line conveys the portion of the separated water back to the bioreactor following processing in the organics treatment system, wherein the portion of the separated water is recycled and forms part of the algae slurry reducing the raw water demand of the bioreactor.
