AI Technical Summary
Existing commercial-scale extraction methods are inefficient and costly, requiring high capital installation and operating costs per amount of processed feedstock, and often result in low product recovery rates.
A continuous stirred tank extraction (CSTE) system and method that processes feedstock in a continuous flow through multiple stages connected in series, optimizing extraction efficiency by controlling temperature, pressure, mixing, and solvent selection, and incorporating solids separation and solvent recovery processes.
The CSTE system achieves high extraction efficiency with reduced capital and operating costs, enabling 24/7 continuous processing and superior product recovery compared to traditional methods, while also allowing for the reuse of solvents and the utilization of spent biomass as a fuel source.
