Abstract:

The present disclosure relates to methodologies, systems, and devices for compressing COfor recycling within a CO-based chromatography or extraction system. A bellows pump can receive COin a gaseous state and can compress the COinto a liquid or partially liquid-vapor state using hydraulic compression. Once compressed, the liquid or liquid-vapor COcan be recycled within the CO-based chromatography or extraction system.

Abstract:

Exemplary embodiments are directed to a diffuser assembly configured to be disposed in an extraction path of an extracting solvent in an extraction vessel. The diffuser assembly includes a housing configured to be disposed within the extraction vessel, the housing including an inner surface and an outer surface. The diffuser assembly includes an inlet structure disposed within the housing. The diffuser assembly includes an outlet structure disposed within the housing and spaced from the inlet structure to form a mixing chamber between the inlet structure and the outlet structure. The inlet structure and the outlet structure each have a porosity configured for passage of the extracting solvent therethrough. Passage of the extracting solvent through the inlet structure, the mixing chamber, and the outlet structure redistributes flow of the extracting solvent along the extraction path.
