Abstract: A system for growing and harvesting algae biomass includes a photo-bioreactor suitable for algae growth in water and a filter unit in fluid communication with the photo-bioreactor. An algae slurry, when at least partially contained within the photo-bioreactor, generates hydrostatic fluid pressure that exclusively drives the algae slurry to the filter unit and discharges a permeate.

Abstract: Systems and methods for algae cultivation and, more particularly, to systems and methods for controlling algae cultivation water solution temperatures to optimize algae facility productivity. Effluent water from harvested algae water solutions is stored based on temperature conditions within storage reservoirs and recycled back into a cultivating algae solution to control the temperature thereof and enhance the growth and robustness of resultant algal biomass.

Abstract: This invention relates to methods and apparatus for harvesting by-product oxygen from algae ponds or bioreactors (collectively, “algal biofuel production”) for use in an oxygen-requiring process that requires oxygen as a reactant such as syngas, hydrogen, or power production processes, which optionally can be integrated with the algal biofuel production. In some embodiments, the invention provides methods that include a method comprising: collecting oxygen from an algal biofuel production process; and using the collected oxygen in an oxygen-requiring process that requires oxygen as a reactant. In some embodiments, the invention provides systems that include an integrated system comprising: an algal bioreactor that produces biodiesel and oxygen, a pipeline for transporting oxygen to an oxygen-requiring process unit so that the oxygen can be used as reactant in the oxygen-requiring process unit, and the oxygen-requiring process unit.

Abstract: A method includes introducing a crude oil process stream into an electro-kinetic separator (EKS), passing the crude oil process stream through an electric field generated by the EKS, and removing at least a portion of salt and solid particles from the crude oil process stream as the crude oil process stream passes through the electric field. A product stream is discharged from the EKS with reduced salt and solid particle count as compared to the crude oil process stream.

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.

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 includes an algae bioreactor that contains an algae slurry, a heat exchanger in fluid communication with the algae bioreactor to receive the algae slurry from the algae bioreactor and heat and increase a pressure of the algae slurry, and one or more valves and a flash vessel in fluid communication with a discharge of the heat exchanger to flash the algae slurry and create steam and algae biomass. A separator receives the algae biomass from the flash vessel and separates oils from the algae biomass to generate a biofuel.
