Condensible Gas Botanical Extraction Systems And Methods
An apparatus for the extraction of compounds from botanical material using a condensable gas solvent includes an extraction chamber and a cyclonic separator. The cyclonic separator includes a cyclone chamber having a cyclonic tangential fluid inlet. A solvent flow path extends from the extraction chamber to the cyclonic tangential fluid inlet. A sonic flow nozzle is positioned in the solvent flow path upstream of the cyclonic tangential fluid inlet.
Claim CLM-00001. 1. Apparatus for the extraction of compounds from botanical material using a condensable gas solvent, the apparatus comprising:
(a) an extraction chamber having a solvent outlet; (b) a cyclonic separator comprising a cyclone chamber having a cyclonic tangential fluid inlet and a fluid outlet; (c) a solvent flow path extending from the solvent outlet of the extraction chamber to the cyclonic tangential fluid inlet; and, (d) a sonic flow nozzle positioned in the solvent flow path adjacent the cyclonic tangential fluid inlet.
Claim CLM-00007. 7. A method for extracting compounds from botanical material using a condensable gas solvent, the method comprising:
(a) in an extraction chamber, using the condensable gas solvent to extract at least one compound from a feedstock of botanical material; (b) withdrawing a liquid solvent containing the at least one compound extracted from the feedstock from the extraction chamber and conveying the liquid solvent through a solvent flow path to a sonic flow nozzle and obtaining solvent at a supersonic velocity; and, (c) directly tangentially introducing the solvent exiting the sonic flow nozzle at a supersonic velocity into a cyclone separator.
Claim CLM-00017. 17. A method for extracting compounds from botanical material comprising cannabis using a condensable gas solvent, the method comprising:
(a) in an extraction chamber, using the condensable gas solvent in a phase comprising at least one of a supercritical phase and a liquid phase to extract at least one compound from the cannabis; (b) withdrawing a liquid stream comprising solvent and the at least one compound and conveying the liquid stream along a solvent flow path extending from the extraction chamber to a cyclone chamber having a fluid inlet; (c) converting the solvent in the liquid stream to a gaseous phase upstream of the cyclone chamber; and, (d) directing the solvent in the gaseous phase into the cyclone chamber via the fluid inlet at sonic velocity.
