A tube heat exchanger extending in a vertical direction, comprising: a first chamber including a lower portion provided with at least one intake inlet for a diphasic fluid including a liquid and a first vapor containing a mist; an upper portion; and a first recovery member passed through by the first vapor and recovering the mist in liquid form, the first vapor next arriving in the upper portion, a central chamber forming liquid films running over the tubes and vaporizing at least partially to produce a second vapor, the tubes being traveled inwardly by a fluid hotter than the diphasic fluid, and a second chamber receiving the first vapor and the second vapor to form a third vapor, and including an outlet for the non-vaporized liquid and an outlet for the third vapor, the first chamber and the second chamber together forming a volume surrounding the central chamber around the vertical direction.

A system and method removes thermal decomposition components from biphenyl and/or diphenyl oxide-based heat transfer fluids. Light, volatile decomposition components including benzene, water, hydrogen and phenol leave the system for vapor recovery, chemical adsorption or thermal decomposition. Dimerized and polymerized heavy components such as biphenyl phenyl ether, terphenyl and related isomers are concentrated and recovered. The system can be a continuous, semi-continuous or batch operation. Solar electric plants employing the system can use solar field fluids and heating to operate the system during generator operation hours. A wash system operating at or near atmospheric pressure concentrates heavy thermal decomposition components while allowing removal of light, volatile decomposition components for separation from the majority of the thermal fluid components. Temperature-controlled condensation of the majority of the thermal fluid components allows collection of the thermal fluid, while allowing light, volatile decomposition components to be removed prior to vent processing.

A vaporization capsule including a liquid active agent absorbed in or adsorbed to a substrate, which may be operated so as to vaporize the liquid active agent. The vaporization capsule includes a capsule body defining a first volume and a second volume. A first cover sealingly engages the capsule body at a first end thereof. The first cover includes an exterior perimeter, an interior wall including a hollow defined between the exterior perimeter and the interior wall portion, and at least one indentation disposed in the interior wall portion, fluidly connecting the first volume and the second volume via the hollow.

The invention concerns an apparatus (10) for separation of components with different volatility in a mixed fluid, said apparatus (10) comprising: a first heat exchanging unit (100) provided with first and second flow path structures (131, 132) forming separate flow paths for a first and a second fluid flow through the first heat-exchanging unit (100); an inlet (118) for feeding the mixed fluid to the apparatus (10); an inlet (119) for feeding steam to the apparatus (10); an arrangement for feeding a cooling medium through the apparatus (10), wherein said arrangement comprises at least one cooling medium inlet (105, 106, 107, 108). The invention is characterized in that the apparatus (10) comprises a second heat-exchanging unit (200) provided with third and fourth flow path structures (233, 234) forming separate flow paths for a first and a second fluid flow through the second heat-exchanging unit (200), wherein the cooling medium arrangement comprises at least one cooling medium inlet (205, 206, 207, 208) arranged in fluid communication with the fourth flow path structure (234) and wherein the first and third flow path structures (131, 233) are arranged in fluid communication with each other.

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.

A crystalline pigment or colorant composition having high color intensity and/or low sugar content, and methods and processes of preparation. The composition may comprise purified fruit and/or vegetable color juices.

A shell-and-tube equipment has a cylindrical geometry and is arranged along a vertical axis. The shell-and-tube equipment comprises an upper chamber and a lower chamber connected to a common tube bundle on opposite sides. The upper chamber is provided with at least an inlet nozzle for inletting a first fluid. The tube bundle is surrounded by a shell provided with nozzles for inletting and outletting a second fluid which exchanges heat with the first fluid through the tube bundle. The upper chamber encloses at least a distribution device configured for uniformly delivering the first fluid towards the tube bundle. The distribution device comprises an annular channel which is arranged around the vertical axis and is in fluid communication with the inlet nozzle. The distribution device comprises a plurality of channel modules of circular trapezoid shape, tightly joined together at their respective vertical edges for forming the annular channel.

The present invention relates to a method of manufacturing spray-dried powders. During the process, a solvent is used. The process is done in multiple steps such that the emulsification mass ratio is low when removal of the solvent is started. Preferred solvents are isopropyl acetate and ethyl acetate. The invention also relates to a set-up to run the inventive process at industrial scale.
