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.

Abstract: The present disclosure relates to methodologies, systems, and devices for collecting extract in a CO2-based extraction system. A diffuser can be used, attached to one end of an extraction tube, in order to depressurize the CO2 and extract mixture as it exits the diffuser and enters the extraction collection container. A splash guard can also be attached to the extraction tube in order to block any splashing of extract while CO2 is allowed to vent from the extraction collection container.

Abstract: The present disclosure relates to methodologies, systems, and devices for compressing CO2 for recycling within a CO2-based chromatography or extraction system. A bellows pump can receive CO2 in a gaseous state and can compress the CO2 into a liquid or partially liquid-vapor state using hydraulic compression. Once compressed, the liquid or liquid-vapor CO2 can be recycled within the CO2-based chromatography or extraction system.

Abstract: The present disclosure relates to methodologies, systems, and devices for discretely collecting extracts from an extract collection container of a CO2-based extraction system. A removable liner can be placed within the extract collection container such that the extract is collected within the removable liner, which can be removed or collected at discrete times. The removable liner can be hung from an extract fluid inlet tube or attached to an internal sidewall of the extract collection container.
