The invention relates to novel crystalline forms of imiquimod formed with ferulic acid, acetic acid, coumaric acid, citric acid, or tartaric acid, to methods of making these cocrystals, and to compositions containing the cocrystals.

The present invention discloses a saline glycerine wastewater treatment system and technology. The whole technological process mainly includes a reaction process, an evaporation process, a crystallization process, a filtration process and a drying process. The present invention first proposes the use of an “ammonia-alkali reaction principle” to treat high-salt glycerine wastewater, which mainly solves the problem of treating a large amount of calcium chloride-containing glycerine wastewater produced in the production process of propylene oxide and epichlorohydrin in chlor-alkali industry, and places emphasis on solving the problems that low value-added calcium chloride produced in the wastewater treatment process of a traditional method has low quality, is basically accumulated as solid waste and is difficult to treat, and chloride ions have adverse effects on the biochemical process of wastewater treatment. By-products of high-quality calcium carbonate and ammonium chloride products have high economic benefits and social environmental protection benefits.

Techniques according to the present disclosure include capturing carbon dioxide from a dilute gas source with a CO.sub.2 capture solution to form a carbonate-rich capture solution; separating at least a portion of carbonate from the carbonate-rich capture solution; forming an electrodialysis (ED) feed solution; flowing a water stream and the ED feed solution to a bipolar membrane electrodialysis (BPMED) unit; applying an electric potential to the BPMED unit to form at least two ED product streams including a first ED product stream including a hydroxide; and flowing the first ED product stream to use in the capturing the carbon dioxide from the dilute gas source with the CO.sub.2 capture solution.

Disclosed is a method for the manufacture of a spray-dried powder consisting essentially of 3-fucosyllactose, the spray-dried powder, its use for the manufacture of nutritional compositions, and nutritional compositions containing the spray-dried powder.

A method of purifying cannabis derived terpenes includes first providing cannabis material having a detectable amount of tetrahydrocannabinolic acid (THCA), adding a solvent to the cannabis material, spinning the cannabis material in a centrifuge to separate crystallized THCA from a high terpene extract. Decarboxilating the THCA with heat to yield tetrahydrocannabinol. The high terpene extract is deposited into a vacuum oven to reduce pressure and volatilize terpenes from the high terpene extract. Next the terpenes are pumped into a cold trap to condense terpenes from the high terpene extract. Next, the condensed terpenes are cooled at a temperature between −50° C. and 0° C. to remove water from the condensed terpenes and yield purified terpenes. The purified terpenes are applied to an edible food product containing decarboxylated tetrahydrocannabinol. In an alternate embodiment, the tetrahydrocannabinol and the purified terpenes are combined or recombined and mixed directly into a precooked edible food product.

Methods and systems are provided for infusing a crystalline and/or porous solid with a desired fluid, particularly an antimicrobial agent, as well as infused crystalline and/or porous solids produced thereby. Solids which may be infused with an antimicrobial agent according to the invention include erythritol, table salt, table sugar, baking soda, calcium carbonate, acetic acid, ascorbic acid, and marshmallow.

Disclosed is a method for the manufacture of a spray-dried powder consisting essentially of LNT and/or LNnT, the spray-dried powder, its use for the manufacture of nutritional compositions, and nutritional compositions containing the spray-dried powder.

A method for utilizing the hard cracking of cannabinoids includes providing a substantially pure cannabinoid isolate; optionally, adding terpenes or other flavor additives; optionally, physically mixing the combination; heating the isolate or mixture to a hard cracking point of the cannabinoid for a period of time; rapidly cooling to form a crystalline cannabinoid.

A method of removing barium and naturally occurring radioactive material from produced water. The method includes pretreating the produced water having a pH in a range of from about 4.0 to about 10.0 with a sulfate source to form a suspension of barium sulfate, radium sulfate, or a combination thereof, treating the pretreated produced water with an anionic flocculant and gravitational])′ separating the treated produced water from the barium sulfate, radium sulfate, or a combination thereof.
