The feasibility of using CO₂ from a concentrated source to grow microalgae is limited by the high cost of CO₂ capture and transportation, as well as significant CO₂ loss during algae culture. Another challenge is the inability of algae in using CO₂ during night while CO₂ is continuously produced from the source. To address these challenges, this invention provides a process in which CO₂ is captured as bicarbonate and used as feedstock for algae culture. Then the carbonate is regenerated in the algae culture process as absorbent to capture more CO₂, which is converted to bicarbonate for use as feedstock, etc. This process significantly reduces carbon capture costs since it avoids the energy for carbonate regeneration. Also, transporting a solid or aqueous bicarbonate solution has a much lower cost than transporting compressed CO₂, and using bicarbonate provides a better alternative for CO₂ delivery to algae culture systems than supplying CO₂ gas.

A modified dryer operates on a different principle from that used by the prior torrefaction plants. The subject invention utilizes thermal conduction to torrefy the biomass in a vibratory reactor in which a heated solid unperforated plate is sealed in the reactor to separate the biomass above from the gas used to heat the plate below. This permits using inert flue gas to heat the reactor which in turn permits the use of a cool air damping system to prevent thermal runaway. Also syngas evolved from the process is utilized to power a gas engine, the exhaust output of which is recirculated to heat the reactor plate. When the gas engine is coupled to an electric generator, waste energy is recovered for use in other parts of the plant or exported elsewhere.
