A system for removing undesirable organic compounds so that the desirable cannabinoids, terpenes, and any other beneficial organic compounds can be easily and effectively captured is provided herein. The system makes use of diatomaceous earth filters through which a solution containing the organic compounds is rinsed with liquid non-polar solvent. The undesirable components remain in the diatomaceous while the beneficial organic compounds pass through and are collected in a liquid solution.

A system and method for crystallization and pelleting of a cannabinoid, including cannabidiol (CBD).

A reaction assembly separating plant material from water includes a first annular filter element defining an axis. The first annular filter element is defined by an outer annular coil of flat wire and an optional second filter element is defined by an inner annular coil of flat wire, being generally helical in the axial direction. A cylindrically or frustoconical filter membrane is concentrically disposed between the first and second annular filter element. The filter membrane is porous having aperture size of less than a nano-particulate size of the plant material, but greater than a nano-particulate size of the water molecule. The second annular filter includes adjustable porosity for selectively preventing particles from reaching the filter membrane and selectively cleaning the membrane by reversed flow of water through the membrane. The assembly generates radial and distal flows and differential pressure forces, for use in high throughput industrial, agricultural and municipal facilities.

Cannabinoids can be separated or extracted from plant material. Versions can include a process for separating trichomes from plant material, including mixing plant material with a fluid in a metered feed system and forming a slurry; pumping the slurry into a turbulent processor, agitating the slurry between rotating and static teeth and shearing trichomes from the plant material to form a mixture of fluid, trichomes and plant material; coarse filtering the mixture and removing portions of the plant material to form an interim mixture; and then second filtering the interim mixture and removing other plant material and some trichomes to form a resulting mixture comprising other trichomes and fluid.

A method of remediating pesticides from an agricultural oil includes mixing a reaction solvent, a reducing agent, and an agricultural oil into a reaction mixture in a reaction vessel, controlling the temperature of the reaction mixture, producing a pre-neutralization mixture including a separation solvent, transferring the pre-neutralization mixture into a neutralization reactor that contains a neutralization agent, mixing the pre-neutralization mixture with the neutralization agent and allowing separation into an aqueous layer and a separation solvent layer, draining the aqueous layer, and distilling the separation solvent in the separation solvent layer from the remediated agricultural oils. A system has a reactor vessel, the reactor vessel having one or more inlets to allow a reducing agent, the agricultural oil, the separation solvent, and other additives as needed to produce a reaction mixture, a temperature control unit to control a temperature of the reaction mixture at a predetermined temperature for a predetermined time, a neutralization vessel fluidically connected to the reactor vessel to receive the reaction mixture from the reactor vessel, the neutralization vessel having an inlet to allow a neutralization agent to be introduced into the neutralization vessel to produce a neutralized reaction mixture, and a valve arranged at a bottom of the neutralization vessel to allow an aqueous phase of the reaction mixture to be drained from the neutralization vessel.

In an embodiment, a method of recovering phenol comprises heating a preheater inlet stream in a preheater to form a splitter inlet stream; separating the splitter inlet stream into a splitter top outlet stream and a splitter bottom outlet stream in a splitter column; separating the splitter bottom outlet stream into a crude top outlet stream and a crude bottom outlet stream in a crude phenol column; hydro-extracting the crude top outlet stream in a hydro-extractor column to form an extractor primary outlet stream; recovering a product phenol outlet stream from the extractor primary outlet stream in a finishing column; combining a bisphenol A plant phenol recovery stream from a bisphenol A reaction from a bisphenol A phenol purification system with the preheater inlet stream, the splitter inlet stream, the splitter bottom outlet stream, the crude top outlet stream, or a combination comprising at least one of the foregoing.

The present invention generally relates to processes for purification, recovery, and conversion of chlorophenol salts (e.g., 2,5-dichlorophenol and salts thereof). In various aspects, the present invention is related to removing one or more impurities from chlorophenol salt-containing process streams and/or recovering chlorophenol salts from process streams for use of the recovered chlorophenol elsewhere in an integrated process. Process streams that may be treated in accordance with the present invention include those incorporating one or more chlorophenol salts in a feed mixture and also those where one or more chlorophenol salts are present in a product or by-product stream of an integrated process. For example, conversion processes of the present invention are suitable as one piece of an integrated process for producing 3,6-dichloro-2-methoxybenzoic acid (dicamba) or a salt or ester thereof or a process for producing 2,4-dichlorophenoxyacetic acid (2,4-D) or a salt or ester thereof. The present invention further relates to processes for preparation, purification, and recovery of intermediates formed in integrated processes utilizing chlorophenol salts such as 2,5-dichlorophenol as starting material, including the intermediate 3,6-dichlorosalicylic acid (3,6-DCSA) formed during preparation of dicamba from 2,5-dichlorophenol.

In alternative embodiments, provided are industrial processes and methods for extracting or removing cannabinoids, flavonoids and terpenes from plant materials such as trichomes. In alternative embodiments, the cannabinoids, flavonoids and terpenes are extracted or removed from the plant materials using a non-polar, organic solvent, or a mixture of non-polar, organic solvent and polar, organic solvent.

A process for selectively recovering a phenolic compound from feedstock comprising bio-crude and/or bio-oil is described. The recovery efficiency of the selected phenolic compound is greater than 70 wt % and the purity of the recovered selected phenolic compound is higher than 80 wt %. The process comprises distilling the feedstock to isolate the selected phenolic compound in a first distillate fraction comprising the selected phenolic compound, concentrating the selected phenolic compound from the first distillate fraction in a concentrated mixture, and purifying the concentrated mixture to recover the selected phenolic compound.

Essential oils, such as CBD oil, are extracted from biomass, such as hemp, in a continuous process. The biomass is delivered to the upper end of a vertically oriented extraction chamber, while a solvent is injected at the lower end thereof. As the solvent flows upwardly, the oil is removed from the biomass. The resulting liquor is collected and purified.
