The invention relates to a method for recovering an organic compound from a feed stream comprising the steps ofextracting the organic compound into an organic solvent, thereby obtaining a mixture of the solvent and the organic compound; andsimultaneously crystallizing the solvent and the organic compound by cooling the mixture; and - separating the solid organic solvent and solid organic compound.

A method is disclosed for treating an aqueous solution containing dissolved materials that are crystallisable by crystallization of clathrates hydrates of a host molecule which crystallize at atmospheric pressure at temperatures higher than the temperature of ice crystallization. This method allows purified water and solid materials or solutions which are highly concentrated in dissolved materials to be produced simultaneously. The disclosure also relates to the implementation of this method.

A method of treating fluids, including for recovery of water apart from impurities or undesired matter, utilizes application of shock waves to the fluids.

In general the present disclosure relates to Nylon 6/montmorillonite clay nanocomposites with enhanced mechanical properties that have been prepared primarily by solution compounding. A major challenge in producing the Nylon 6/montmorillonite clay nanocomposites is associated with the exfoliation and dispersion of the clay particles within the polymer matrix. This disclosure presents compositions and methods for obtaining highly or fully exfoliated nylon 6/montmorillonite nanocomposites, not only for organically modified clays with known compatibility with nylon 6 (Cloisite 30B), but also for clays with low/no compatibility with nylon 6 (Cloisite 15A and Na.sup.+-MMT) through solution compounding.

The present invention includes a method for obtaining a higher purity cannabinoid solvent extract from a plant which comprises cannabinoids and/or terpenes. A solvent extraction is performed on the optionally dried plant material, followed by a step of removing high molecular weight impurities by a cooling step. Following the cooling step, the precipitate is removed and a higher quality filtrate is obtained which contains higher levels of purity of cannabinoids and/or terpenes than the starting solvent extract. The methods of the invention also include a method for obtaining crystallized THCa, which comprises obtaining a filtrate by the methods disclosed herein, or obtaining a solvent extract, and allowing crystallization of the THCa to occur. The filtrate, crystallized THCa, and residual filtrate remaining after crystallization of THCa can be used as starting materials for products that include cannabinoids and/or terpenes.

The present disclosure is directed to a process. In an embodiment, the process includes providing a boric acid solution composed of from 10 wt % to 25 wt % boric acid at a temperature from 60 C. to less than 100 C. to form a heated boric acid solution. The process includes first passing the heated boric acid solution through a first nanofiltration membrane at a pressure from 300 psi to 500 psi to form a first heated boron permeate and second passing the first heated boron permeate through a second nanofiltration membrane at a pressure from 300 psi to 500 psi and forming a second heated boron permeate. The second heated boron permeate is composed of at least 10 wt % boric acid, less than 5 ppm sodium, and less than 5 ppm of a component selected from calcium, lithium, sulfur, and silicon.

Disclosed embodiments include systems and methods for obtaining desired organic compounds from harvested biomass. Some examples include an extraction vessel and a distillery system, where the extraction vessel is configured to wash harvested biomass with a process solvent to obtain a liquid extract, and where the distillery system is configured to distill the extract to separate the process solvent from the extract and obtain a distillate from the extract. Some embodiments additionally include a speedloader configured to load harvested biomass into the extraction vessel and a discharge gantry configured to remove processed biomass from the extraction vessel. In some embodiments, the extraction vessel, distillery system, speedloader, and discharge gantry are mobile and can be deployed in field at a harvest location.
