Abstract:
A distiller including an evaporator having at least one evaporation surface for evaporating liquid into vapor. At least one movable liquid applicator assembly has a wiper applicator which can move over the at least one evaporation surface, for wiping and applying a thin even film of the liquid on the at least one evaporation surface for evaporation.
Abstract:
A liquid evaporator (1, 101) comprises an evaporation chamber (2, 102) with a liquid inlet (3, 103), a condensation chamber (4, 104) with a liquid outlet (5, 105), a heat conducting wall (6, 106) arranged with an evaporation surface (7, 107) in the evaporation chamber (2, 102) and a condensation surface (8, 108) in the condensation chamber (4, 104), a pump structure (9, 109) and a fluid connection passage (10, 110) between the evaporation chamber (2, 102) and the condensation chamber (4, 104), the evaporation chamber (2, 102) being adapted to contain a liquid (11, 111), whose surface (12, 112) delimits a gas pocket (13, 113), the connection passage (10, 110) ending in the gas pocket (13, 113). Thus, gas is pumped from the gas pocket (13, 113) through the connection passage (10, 110) to the condensation chamber (4, 104), the gas is condensed in the condensation chamber (4, 104) under emission of heat energy, a part of the heat energy is transferred through the heat conducting wall (6, 106) from the condensation chamber (4, 104) to the evaporation chamber (2, 102), and the condensate (26) is led away from the condensation chamber (4, 104) through the liquid outlet (5, 105). The advantage of the new liquid evaporator (1, 101) is that it can be made with a smaller number of components than state of the art liquid evaporators with vapour compression.
Abstract:

Abstract:
Ein Dünnschichtverdampfer mit einer senkrecht stehenden Trommel (1), einer im oberen Bereich der Trommel (1) angeordneten Zuführung (4) für ein zu verdampfendes Medium, einem an ihrem Umfang angeordneten, Brüden bildenden Heizmantel (3), einer den Rückstand im unteren Endbereich der Trommel ableitenden Ableitung (20) sowie einem mit einem Kühlmedium versorgten Kondensator (11), ist zur Erhöhung der Trennleistung und gegebenenfalls zur Durchführung chemischer Reaktionen dadurch gekennzeichnet, dass auf dem Weg der Brüden vom Heizmantel (3) zum Kondensator (11) eine die Wirkungsweise des Dünnschichtverdampfers beeinflussende Inneneinrichtung (24) vorgesehen ist.
Abstract:
A single-vessel method is provided for preparing liposomes in commercial quantities by forming a homogeneous and uniform lipid film in a thin-film evaporator (10, 70) by evaporation of the organic solvent, followed by in situ hydration of the film in an aqueous phase by agitation with the rotor (30, 80).
Abstract:
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.
Abstract:
Systems and methods for generating a thin film of a fluid are described. In an embodiment, a fluid support structure may be configured to receive a fluid, such as water, at a top surface and to support the fluid over at least a portion of the top surface. Channels may be formed in the top surface of the fluid support structure. Wiper blades may be configured to move over the top surface in contact with at least a portion of the fluid to form the fluid into a thin film. The wiper blades may include protrusions corresponding to the channels. As the wiper blades move over the top surface, the protrusions may move within the channels forming a thin film of the fluid within the channels. According to some embodiments, the fluid support structure may be configured as an evaporation surface configured to facilitate the evaporation of the fluid.
Abstract:
A method cleaning a contaminate 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.
Abstract:
Disclosed is a process/system for the fractionation of bio-oil, produced from the thermo-catalytic conversion of biomass, into boiling point fractions. The fractionation of the bio-oil is performed using molecular distillation under conditions which minimize the thermal stress to the bio-oil and fractions obtained therefrom.

Die von zwei stirnseitigen Endplatten 311 und 331 begrenzten, wahlweise eine Strömung in axialer Richtung erzeugenden Schikanen in Form von Flügelblättern 3 eines in einer Flüssigkeit 1 eingetauchten und über eine Welle 2 angetriebenen Rotors erzeugen einen durch die stationäre Schikane 51 radial nach aussen begrenzten rotierenden Flüssigkeitsbereich 11 mit der Decke 12 unter Bildung eines unter vermindertem Druck befindlichen Hohlraums mit einer für den Verdampfungsvorgang zur Verfügung stehenden Mantelfläche 13, welche durch das Gleichgewicht der durch die Masse der rotierenden Flüssigkeit erzeugten Zentrifugalkraft mit der Gegenkraft, erzeugt aus der Summe des auf die Flüssigkeit von aussen einwirkenden atmosphärischen und dem durch die lokale Tauchtiefe des Rotors aufgebauten Druck einerseits sowie dem im Hohlraum herrschenden Unterdruck andererseits bestimmt wird, wobei der aus der Mantelfläche 13 in den Hohlraum übergetretene Dampf entsprechend Pfeilen 92 über radiale Kanäle 23 und den in der Welle 2 zentral angeordneten Kanal 22 in nach aussen geführt und über eine Drehdichtung und eine Leitung einem Kondensator mit nachgeschalteter Vakuumpumpe zugeführt wird.
