<i>Cannabis </i>production systems and methods
A vertically-integrated cannabis-related product production method is described, the method comprises, producing a distilled cannabinoid and/or a crystallized cannabinoid from cannabis plants, comprising: in a farming system, growing the cannabis plants, the cannabis plants comprise a cannabinoid; in an extraction system, extracting the cannabinoid from the cannabis plants; in a purification system, purifying the cannabinoid to produce a purified cannabinoid; and in a distillation and/or a crystallization system, distilling and/or crystallizing the purified cannabinoid to produce the distilled cannabinoid and/or the crystallized cannabinoid. Various ways to purify, distill, and process the cannabinoids are described. An insect pest management system may be integrated with the farming system to grow the cannabis plants in the presence of predatory mites which feed on insects and/or spider mites.
Continuous crystallization of cannabinoids in a stirred-tank reactor
Disclosed herein is a method for continuously preparing crystalline cannabinoid particles. The method includes preparing a cannabinoid-rich solution that comprises a first cannabinoid and inducing the cannabinoid-rich solution to a supersaturated state in which the first cannabinoid has a supersaturated concentration that is greater than a corresponding saturation concentration of the first cannabinoid. The method includes flowing the cannabinoid-rich solution into a continuous stirred-tank reactor (CSTR) in a continuous manner, mixing the cannabinoid-rich solution under turbulent mixing conditions to form a plurality of crystalline cannabinoid particles and a cannabinoid-depleted solution within the CSTR, and discharging the plurality of crystalline cannabinoid particles and the cannabinoid-depleted solution from the CSTR in a continuous manner to provide a flow rate through the CSTR. The method includes separating crystalline cannabinoid particles from the plurality of crystalline cannabinoid particles and the cannabinoid-depleted solution in a continuous manner.
A HYBRID PROCESS AND SYSTEM FOR RECOVERING WATER
A hybrid process and system for separating water from an inlet brine solution is disclosed. The hybrid process couples at least two different separation processes/systems. The inlet brine solution is fed into a first separation process, which produces a water distillate and a brine concentrate. The brine concentrate from the first separation process is then fed into the second separation process to further recover additional water. The excess heat from the second separation process is supplied to the first separation process.
METHOD AND APPARATUS FOR REMOVING SULFUR OXIDES FROM GAS
Methods, apparatus, and compositions for cleaning gas. The use of segmented multistage ammonia-based liquid spray with different oxidation potentials to remove sulfur compounds from gas. The use of different oxidation potentials may reduce unwanted ammonia slip.
Nitride stabilized core/shell nanoparticles
Nitride stabilized metal nanoparticles and methods for their manufacture are disclosed. In one embodiment the metal nanoparticles have a continuous and nonporous noble metal shell with a nitride-stabilized non-noble metal core. The nitride-stabilized core provides a stabilizing effect under high oxidizing conditions suppressing the noble metal dissolution during potential cycling.
Method for treating lignocellulosic materials
A method of generating a refined sugar stream that comprises xylose from a biomass hydrolysis solution, including contacting a biomass hydrolysis solution that includes a population of mixed sugars comprising xylose, an acid, and impurities, with a thermally-phase separable solvent such as a glycol solvent to form an extraction mixture; and separating from said extraction mixture a first stream including the thermally-phase separable solvent, acid, and impurities and a second, refined sugar stream that comprises xylose. The thermally-phase separable solvent is an ethylene glycol or a propylene glycol ether, such as 2-butoxyethanol or 1-propoxy-propanol or any combination thereof.
Production of heavy brines by calcination of carbonates using plasma arc reactor
Embodiments relate to systems and methods directed towards arrangements of a preheater, a heat exchanger, a plasma recovery system, and at least one processing stage configured to use steam output of a calciner for heating incoming wastewater that is being processed.
METHOD FOR PREPARING L-METHIONINE CRYSTALS USING CRYSTALLIZATION TECHNIQUE
The present application relates to a method for preparing L-methionine crystals with an improved bulk density. As the L-methionine crystals prepared according to the method for preparing L-methionine crystals of the present application may have a bulk density of up to 800 g/L, the L-methionine crystals are expected to reduce storage and transport costs of L-methionine powder and improve working conditions due to improved fluidity of the powder.
Synthesis of tyrosine derived diphenol monomers
A method for preparing diphenol compounds includes adding a hydroxyphenyl carboxylic acid, a tyrosine ethyl ester, hydroxybenzotriazole hydrate and a solvent and stirring to produce a first solution. EDCI HCl is added to the first solution to produce a first mixture. Ethyl acetate is added to the first mixture to produce a second mixture. The second mixture is added to sodium chloride to produce a third mixture having layer separation. An aqueous layer is removed from the third mixture. The third mixture is extracted with reagents after the aqueous layer has been removed from the third mixture to produce a fourth mixture. Magnesium sulfate is added to the fourth mixture to produce a fifth mixture. The fifth mixture is filtered to produce filtrate. The filtrate is concentrated. Crystallization of the concentrated filtrate is induced. Methylene chloride is added to the crystallized filtrate to produce a solid product.
METHODS FOR EXTRACTING HYDROXYCINNAMIC ACIDS FROM LIGNO-CELLULOSE
Methods for isolation of ferulic acid and/or p-coumaric acid from lignin paste that may be a resulting waste product from the bioethanol process using sugarcane bagasse or corn stover.
