A distillation apparatus includes at least one evaporation space in which feed water is evaporated into a vapour and at least one condensation space, in which vapour from a preceding evaporation space is condensed into distillate. The evaporation space and the condensation space each include a chamber and a plurality of interdigitated pockets arranged between said chambers, such that a first pocket of the evaporation space is present between a first and a second pocket of the condensation space, and that the first pocket of the condensation space is present between the first and a second pocket of the evaporation space. The spaces are mutually separated by means of a separation barrier that is configured for transmission of heat and for definition of the interdigitated pockets.

A method and apparatus for extracting botanical oil from botanical mass includes milling the biomass and chilling the milled biomass. The biomass is then exposed to a chilled ethanol solvent. Water is added and the solution introduced into a first centrifuge. The clean ethanol slurry is then introduced into an evaporator leaving a two-phase mixture which is introduced into a second centrifuge which separates the water from the pure botanical oil.

An apparatus for evaporative concentration of water, containing hardness-causing substances, to be treated using hot lime softening, includes: a first evaporator configured to form first concentrated water from the water to be treated by evaporatively concentrating the water by first heat exchange with hot steam; a hot lime softener configured to precipitate and to separate hardness-causing substances contained in the first concentrated water from at least a portion of the first concentrated water from the first evaporator by reaction with lime and configured to remove the hardness-causing substances from the first concentrated water; and a second evaporator configured to form second concentrated water by further evaporatively concentrating at least a portion of the first concentrated water that passed through the hot lime softener by second heat exchange with hot steam.

Methods may include obtaining ketones and glycols from a fermentation process, the method including: collecting an off-gas and/or a fermented broth from the fermenter, wherein the off-gas comprises a ketone, and wherein the fermented broth comprises one or more of glycol or ketone; and performing at least one of: transferring the off-gas from the fermenter to a ketone recuperation module; or transferring the fermented broth to a fluid separating module; and isolating one or more of: the ketone from the off-gas; and the glycol from the fermented broth.

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.

The present disclosure relates a system for the treatment of water. The water treatment system may be linked an aquatic protection system or a water filtration system.

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.

The invention is a high-salt waste water air powered low temperature evaporating device and method of use. A tray is mounted on a lifting platform; an air inlet and a water inlet are on the tray. Air distributing pipes are arranged at the center of the nested column tubes (33). A groove (4) is installed at the top of the tray, and mounting points are accompanied by multiple nested column tubes (33). The nested column tubes (33) are connected with the air inlet. An atomizer is arranged inside the air distributing pipes; and the atomizer is connected with the water distributing pipes. Using air power evaporates concentrated waste water multiple times so that the salt in the wastewater reaches saturated concentration, and therefore, the wastewater temperature is reduced, salt is crystallized and separated out, liquid is continuously evaporated, and the wastewater can be completely treated.

Processes for the separation of water from a mixture of water with other components, comprising the following steps: A) providing feed material FM comprising water and at least one a nonionic surfactant S in an amount of 0.1 to 1000 ppm by weight based on the feed material FM, B) subjecting said feed material FM to a distillation step using a falling film evaporator.

A heat transfer fluid comprising about 20 to about 80% by weight terphenyls and from about 20 to about 80% by weight partially hydrogenated terphenyls, wherein preferably the terphenyls and partially hydrogenated terphenyls comprise a reclaimed product from a degraded heat transfer fluid initially comprised primarily of partially hydrogenated terphenyls.
