Abstract: A CO2 extraction process for Cannabis sativa that uses liquid CO2 in combination with co-solvent admixtures to purify cannabis botanicals in high yield and purity. The extraction process allows for multiple extractions, or washes, to be performed with the same solvent CO2, which may be seamlessly recycled and purified between subsequent extraction cycles. A variety of in-line filtration vessels, pumps, vacuums, and controllable valves are used to yield a pure product while allowing a high level of user control over the process.

Abstract: Targetry coupled separation refers to enhancing the production of a predetermined radiation product through the selection of a target (including selection of the target material and the material's physical structure) and separation chemistry in order to optimize the recovery of the predetermined radiation product. This disclosure describes systems and methods for creating (through irradiation) and removing one or more desired radioisotopes from a target and further describes systems and methods that allow the same target to undergo multiple irradiations and separation operations without damage to the target. In contrast with the prior art that requires complete dissolution or destruction of a target before recovery of any irradiation products, the repeated reuse of the same physical target allowed by targetry coupled separation represents a significant increase in efficiency and decrease in cost over the prior art.

Abstract: A method for producing a diesel having improved cold flow properties, the method comprising the steps of introducing a crude oil to a distillation column, separating the crude oil in the distillation unit to produce a light gas oil, and a light vacuum gas oil, where the light gas oil has a T95% cut point in the range between 300 deg C. and 340 deg C., where the light vacuum gas oil has a T95% cut point in the range between 400 deg C. and 430 deg C., processing the light vacuum gas oil in the supercritical water unit to produce an upgraded vacuum gas oil, separating the upgraded vacuum gas oil in the fractionator to produce an upgraded light fraction, an upgraded light gas oil, and upgraded heavy fraction, introducing the upgraded light gas oil into a diesel pool, and blending the light gas oil into the diesel pool.

Abstract: Method and system for the extraction of oils from a biomass with a liquid carbon dioxide using cosolvent. The system and method can be used to extract cannabinoids from Cannabis biomass by cryogenically freezing the biomass and exposing the Cannabis biomass to sub-cooled liquid carbon dioxide and capturing a first high-terpene extract fraction, and then exposing the Cannabis biomass with a mixture of superfluid carbon dioxide and a cosolvent to capture a high cannabinoid second fraction.

Abstract: This disclosure provides methods and systems for the supercritical fluid extraction of cannabinoids from cannabis. The supercritical fluid extraction of cannabinoids is performed with carbon dioxide (CO2) balanced with one or more hydrocarbons, such as propane, propene, and propadiene. As demonstrated, the extraction can be carried out at maximum efficiency and energy savings while keeping the wax formation at minimum by lowering temperature. The methods and systems disclosed herein reduce the production time and safety/environmental hazards and are suitable for proper and safe extraction in non-GMP and GMP environments.

Abstract: In a system and process for selectively purifying various pharmacologically-relevant components of a source plant such as cannabis, an initial step provides a low-temperature, robust essential oil/terpene capture that also dehydrates and decarboxylates the starting product—fresh raw cannabis—by means of a vacuum-assisted microwave distillation process. By doing the terpene capture under vacuum distillation temperature may be kept low. The low distillation temperature maximizes yields of thermally-sensitive components such as terpenes and cannabinoids. The system includes an oil/water separator configured to prevent leakage of ambient air into the system.
