The small-sized water treatment equipment providing high water treatment efficiency without using multi-stage structure in the water treatment equipment for obtaining fresh water from raw water, including sea water.

The water treatment equipment 10 comprises the evaporation parts 11 and 12, the condenser part 13 and the heat exchanger 24, and the raw water, including sea water, being introduced within the equipment circulates between the evaporation parts 11 and 12 and the heat exchanger 24 via circulating the circulation paths 40a to 40d. Further, circulating water circulates between the condenser part 13 and the heat exchanger 24 via circulating the circulating water circulation paths 41a to 41c, being vaporized at the evaporation parts 11 and 12 and cause vapor-liquid contact in the condenser part 13 with the steam that has circulated the air flow channels 42a to 42c. The circulating water that passed the condenser part 13 and the raw water that passed the evaporation parts 11 and 12 exchange heat at the heat exchanger 24.

A system for processing a fluid by generating water vapor through forced compression and rotation in a vessel includes capturing sea water for use in desalination processing in the vessel. Any fluid processed in the vessel, including sea water, can be used to create water vapor that rises to an elevation under its own power. After condensing the water vapor to liquid again, the condensed liquid falls upon a hydro-electric generator to generate electricity that is stored for later use. Brine output from the system can be recycled for re-processing through the system to increase water vapor yield. The wet brine output may also be dried to produce dried brine for subsequent processing of salt and other minerals.

Systems and methods for separating components from a fluid stream are described. The systems and methods described herein may be specifically well suited for separating solids, hydrocarbons, chemicals, non-evaporable components, etc., from wastewater produced by oil and gas recovery. The systems and methods may generally include the use of a heat exchanger through which a fluid stream is passed to thereby evaporate some or all of the fluid stream. The heated stream exiting the heat exchanger may include vapor, liquids and/or solids. This heated stream is then subjected to phase separation to separate a vapor stream from a liquid/solids stream. The vapor stream is then transported back to the heat exchanger where it is used to transfer heat from the vapor stream to the fluid stream. During the operation of the heat exchanger, a scraping system may be used to scrape the one or more surfaces of the passage through which the fluid stream flows in order to prevent buildup of solids and liquids thereon.

The present invention describes a method which outlines a process for conversion of CBD to a ?.sup.9-tetrahydrocannabinol (?.sup.9-THC) compound or derivative thereof involving treating a naturally produced CBD intermediate compound with an organoaluminum-based Lewis acid catalyst, under conditions effective to produce the ?.sup.9-tetrahydrocannabinol compound or derivative thereof at a relatively high concentration. The source of the CBD is from industrial hemp having less than 0.3% ?.sup.9-THC and extracting and purifying a CBD distillate or isolate or a combination thereof. This procedure will produce ?.sup.9-THC that is essentially free from any other cannabinoids other than some trace amounts of the initial CBD starting material, or about 95% ?.sup.9-THC and 2-4% CBD. Another aspect of the present invention relates to a process for further purification and enrichment of the ?.sup.9-THC using distillation and collecting an essentially pure fraction of ?.sup.9-THC using additional distillation or enrichment form of purification. Included are methods and processes to scale the reaction from the lab to large scale manufacturing. Included are methods for adding a molecule marker to authenticate high purity ?.sup.9-THC products. Formulations and uses for pharmaceuticals, nutraceuticals, food products, and topicals are also provided.

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.

The present disclosure provides for a continuous drying apparatus and a method of using the apparatus in the preparation of dried solids from slurries. The methods and apparatus are useful for the production of fine chemicals and pharmaceuticals, particularly using Integrated Continuous Manufacturing (ICM), but can also be integrated with other manufacturing processes, such as batch and semi-continuous processes.

A method for cleaning a contaminated solvent used to treat a gas stream, for example a contaminated glycol or a contaminated amine stream, by vacuum evaporation using a mechanically-maintained horizontally-orientated thin film evaporator, where the contaminant material is recovered from the thin film in solvent-free form, as either a heavy organic material or as free flowing salts.

A method for isolating a phenylene ether oligomer composition includes feeding a solution including a solvent and a phenylene ether oligomer into a thin film evaporator, forming a film on an interior surface of the thin film evaporator, and heating to devolatilize the solvent from the film, to provide a phenylene ether oligomer composition. The thin film evaporator includes cylindrical heating chamber and a rotor having one or more rotor blades, wherein an edge of the one or more rotor blades and the interior surface of the cylindrical heating chamber are separated by a distance of 0.5 to 3.5 millimeters. Phenylene ether oligomer compositions are also described.

A process for treating a fluid includes: a step of introducing fluid to treat into a chamber of a dryer, a step of drying the fluid in the chamber including a first phase during which a weight of the chamber reduces and when the weight of the chamber reaches a lower threshold or a rate of variation of the weight of the chamber is less than a first predefined value, the drying step includes a step of complementary filling of the chamber until the weight of the chamber reaches an upper threshold and a second phase during which the weight of the chamber decreases and when the rate of variation of the weight is less than a second predefined value, the process includes a step of extracting a solid residue in powder form. The invention also concerns an installation for implementing the process.
