INTEGRATED PHOTOBIOREACTOR-BASED POLLUTION MITIGATION AND OIL EXTRACTION PROCESSES AND SYSTEMS

摘要

Integrated systems including a photobioreactor system designed to contain a liquid medium comprising at least one species of phototrophic organism therein, and a facility associated with extracting and/or processing oil extracted from mixtures of oil and solid material, such as an oil sands facility, are described. Processes for using a photobioreactor system as part of a gas-treatment process and system able to at least partially remove certain undesirable pollutants from a byproduct gas stream produced by an oil sands facility are also described. Examples of such pollutants that may be removed include compounds contained within combustion gases, e.g., CO2 and/or NOx. These pollutants processed with the photobioreactor system and/or biomass produced with the photobioreactor system may be utilized to produce a fuel source (e.g., biodiesel) and cutting stock for further operation of or use in the oil sands facility. Such uses of certain embodiments can provide an efficient means for recycling carbon, thereby reducing CO2 emissions, fuel, and/or cutting stock requirements for a given quantum of energy produced.
