Methods and systems are provided for recovering an organic solvent from a waste sludge generated during formation of a polyarylene sulfide. Methods include combining the waste sludge with a liquid extractant that extracts the organic solvent into a homogeneous liquid phase. Upon a temperature change, the homogeneous liquid phase can separate into an organic solvent-rich liquid phase and a liquid extractant-rich liquid phase. The two liquid phases can be separated and further processed if desired to further purify the recovered organic solvent. Methods can also include forming the polyarylene sulfide by a polymerization process and thereafter purifying a slurry of the polyarylene sulfide. A liquid washing product is formed as a result of the purification process, which can be subjected to a distillation process that forms an organic solvent-rich stream and the waste sludge.

The disclosure provides methods and compositions for providing shatter formulations taking the form of crystalline polymorphs, where methods of preparation include preparing tetrahydrocannabinol acid (THCA) powder followed by decarboxylating THCA and removal of terpenes.

A method of extracting one or more chemical extracts from a plant product includes mixing at least a first phytochemical-bearing part of a phytochemical plant product with an oil-bearing plant product, producing an oil mixture from the first phytochemical-bearing part and the oil-bearing plant product using a press device, and extracting at least a chemical extract from the oil mixture.

A method for extracting and isolating terpenes and aromatic compounds from Cannabis plant material by the steps of grinding the cannabis plant material to obtain a ground cannabis, performing a CO2 supercritical extraction upon a first portion of the ground cannabis, wherein said supercritical extraction is performed at temperature below freezing, between −30 to 0 centigrade, for a period of 3 to 5 hours, at between 1000-1300 psi, performing a steam distillation upon a second portion of the ground cannabis, performing a butane extraction upon a third portion of the ground cannabis, wherein the butane extraction is performed at a temperature between −30 to 0 centigrade, performing an alcohol extraction upon a fourth portion of the ground cannabis, wherein the alcohol extraction is performed at a temperature between −30 to 0 centigrade, performing a maceration upon a fifth portion of the ground cannabis, wherein the maceration is performed with coconut oil at a temperature of between 40-70 centigrade, combining at least a portion of each of the resultant extracts from the CO2 supercritical extraction step, the steam distillation step, the butane extraction step, the alcohol extraction step and the maceration step to create a combined extract, and then fractionally distilling the combined extract to separate terpenes and other aromatic compounds from the combined extract.

The interaction system that causes an interaction between a first fluid and a second fluid includes a plurality of processing units configured so as to cause the second fluid separated in the separation container of each of the plurality of processing units to flow into the processing channel of the interaction unit of a processing unit that is next in flow order to the each of the plurality of processing units, the separation container of the each of the plurality of processing units is connected to the processing channel of the interaction unit of the processing unit that is next in the flow order, a first fluid feeding path that leads the first fluid separated in the separation container of a succeeding stage processing unit among the plurality of processing units from the separation container to the processing channel of the interaction unit of a preceding stage processing unit, a storage container that stores the first fluid led out from the separation container of the succeeding stage processing unit to the first fluid feeding path, and a delivery fluid supply unit that supplies a delivery fluid to the storage container so that the first fluid in the storage container is pushed out by the delivery fluid to flow through the first fluid feeding path into the processing channel of the preceding stage processing unit.

A plant oil extraction device includes one or modules for extraction of a product, e.g., oil, from a plant biomass. Various embodiments of the plant oil extraction device are described that include one or more features for producing a clean organic stream, free from waxes and terpenes, from biomass feedstocks such as industrial hemp. Related systems, methods, and articles of manufacture are also described.

Disclosed are extraction solvents used in compositions and methods to refine synthetic feedstocks derived from plastic. Methods of refining plastic-derived synthetic feedstocks are also provided. For example, a method of refining a plastic-derived synthetic feedstock composition may include adding an extraction solvent to a synthetic feedstock composition derived from plastic pyrolyis to provide an extract phase and a raffinate phase, wherein the extraction solvent includes a polar organic extraction solvent immiscible in the synthetic feedstock. The methods may also include separating the raffinate phase from the extract phase to obtain a refined synthetic feedstock.

This invention relates to the extraction of psychoactive compounds from organisms for use in medicine. Extraction is carried out with a strong acid or strong base to either promote or inhibit dephosphorylation. The extract in the slurry form is standardized with added excipient so that when it is dried the powdered composition has a specified total psychoactive alkaloid concentration, with a known ratio of phosphorylated to dephosphorylated psychoactive alkaloids.
