Abstract
A method of remediating cannabinoid containing compositions includes contacting the compounds with an aqueous solution to remove at least one impurity therefrom. The method may include additional contacting with further aqueous solutions of the same or different kind in order to remove additional impurities or higher amounts of the same impurity. A system for remediating cannabinoid containing compositions includes a cannabinoid containing composition supply and an aqueous solution supply fluidly coupled to a conduit reactor and a separator for collecting reaction products between the compound and the aqueous solution.
Claims20
A method comprising:
- simultaneously introducing a cannabinoid containing composition and a first aqueous solution into a first end of a first conduit reactor comprising a plurality of fibers disposed therein;
- collecting first reaction products in a first separator disposed opposite the first end;
- wherein the cannabinoid containing composition is immiscible with water and comprises a cannabinoid, a first impurity, and a second impurity, where the first and second impurities may be of the same kind or of different kinds;
- and
- wherein the first reaction products comprise a first organic phase comprising the cannabinoid and the second impurity, and a first aqueous phase comprising the first aqueous solution and the first impurity;
- simultaneously introducing the first organic phase and a second aqueous solution into the first end of the first conduit reactor or into a first end of a second conduit reactor comprising a plurality of fibers disposed therein, wherein the second aqueous solution may be of the same kind or of a different kind than the first aqueous solution;
- collecting second reaction products in the first separator or in a second separator disposed opposite the first end of the second conduit reactor;
- wherein the second reaction products comprise a second organic phase comprising the cannabinoid and a second aqueous phase comprising the second aqueous solution and the second impurity;
- and
- separately removing the second organic phase.
A system comprising:
- a cannabinoid supply comprising a cannabinoid containing composition disposed therein, wherein the cannabinoid containing composition comprises a cannabinoid, a first impurity, and a second impurity;
- a first aqueous supply comprising a first aqueous solution disposed therein;
- a second aqueous supply comprising a second aqueous solution disposed therein, wherein the second aqueous solution has a different pH than the first aqueous solution;
- a conduit reactor comprising a plurality of fibers disposed therein and a first end coupled to the cannabinoid supply, the first aqueous supply, and the second aqueous supply;
- a separator positioned opposite the first end and configured to accept reaction products from the cannabinoid containing composition and the first aqueous solution or the second aqueous, wherein said reaction products include an organic phase comprising the cannabinoid and an aqueous phase comprising the first aqueous solution and the first impurity or the second aqueous solution and the second impurity;
- a sensor positioned within the separator and configured to measure a pH of the aqueous phase;
- and
- a recirculation line comprising a pump and configured to direct the organic phase from the separator to the first end of the conduit reactor.
