摘要： A gas separator includes a first distillation chamber and an evaporation chamber. A first liquid valve comprises an inlet in fluid communication with the first distillation chamber and an outlet in fluid communication with the evaporation chamber. A chiller is configured to chill the first distillation chamber to a first temperature and the evaporation chamber to a second temperature that is different than the first temperature. The gas separator operates a first mode during which distillation a gas mixture is received by the first distillation chamber, the gas mixture is separated into a first condensed liquid and a first separated gas mixture, and the separated gas is output by the first distillation chamber. During a second mode, the first liquid valve transfers the first condensed liquid to the evaporation chamber and the first distillation does not receive the gas mixture and does not supply the first separated gas mixture.

摘要： The present disclosure relates generally to processes and systems for distillation of acetic acid products. In one aspect, the disclosure provides a process for separating a feed stream comprising acetic acid and propionic acid in a distillation column. The process includes introducing a feed stream into the column through a feed inlet; withdrawing a first product stream comprising acetic acid and propionic acid from a first draw outlet disposed at a level above the level of the feed inlet; and withdrawing a second product stream comprising acetic acid and propionic acid from a second draw outlet disposed at a level between the level of the feed inlet and the level of the first draw outlet. The volume ratio of the first product stream to the second product stream is in the range of 1:9 to 19:1; and the amount of propionic acid present in the second product stream is at least 50 ppmw greater than the amount of propionic acid present in the first product stream.

摘要： L'invention concerne un procédé de transfert thermique entre un premier et un deuxième fluide dans lequel le premier et le deuxième fluide circulent respectivement de part et d'autre d'une paroi thermiquement conductrice (3) d'un ensemble monobloc (1) formé d'un seul tenant agencé à l'intérieur d'un dispositif (10), l'ensemble monobloc (1) comportant: - une première structure tridimensionnelle alvéolaire thermiquement conductrice (2) apte à être traversée par le premier fluide, - au moins ladite paroi (3), et - une deuxième structure tridimensionnelle alvéolaire thermiquement conductrice (4) apte à être traversée par le deuxième fluide, la première structure tridimensionnelle alvéolaire (2) et la deuxième structure tridimensionnelle alvéolaire (4) étant situées de part et d'autre de ladite paroi (3) et solidaires de ladite paroi (3), de sorte que le transfert thermique est réalisé du premier fluide vers le deuxième fluide à travers ladite paroi (3) et que chacun des premier et deuxième fluides est à la fois sous phase liquide et sous phase gazeuse, la phase liquide du premier fluide circulant dans un sens opposé à la phase gazeuse du premier fluide et la phase liquide du deuxième fluide circulant dans un sens opposé à la phase gazeuse du deuxième fluide.

摘要： Der Erfindung, die ein Verfahren und eine Vorrichtung zur Reinigung von verschmutzten Altöl betrifft, bei dem Ausgangsmaterial bis zur Gasphase erwärmt und der dabei entstehende Dampf rektifiziert wird, wobei gereinigtes Öl als Kondensat aus einem Abzug in einer Rektifikationskolonne entnommen wird, liegt die Aufgabe zugrunde, ein Verfahren und Vorrichtung zur Reinigung von verschmutztem Altöl anzugeben, welches auch in Kleinstanlagen eine effiziente Arbeit ermöglicht, so dass eine kompakte Anlagenkonfiguration und damit insbesondere ein mobiler Einsatz durch einen Containeraufbau ermöglicht wird. Der Erfindung liegt auch die Aufgabe zugrunde, den Aufwand für die Wartung zu verringern. Die erfindungsgemäße Aufgabenstellung wird dadurch gelöst, dass Altöl einer Verdampfung durch eine zumindest mittelbare Kontaktierung des Ausgangsmaterials mit einem Schmelzbad, dessen Schmelztemperatur über der Verdampfungstemperatur jedoch unter der Zündtemperatur des Altöls liegt, unterzogen wird und der Dampf in der Rektifikationskolonne rektifiziert wird.

摘要： An apparatus for separating a feed stream into product streams. The apparatus includes an upper section, a middle section, and a lower section. The middle section has a dividing wall separating it into two portions. A liquid barrier blocks the flow of liquid from the upper section into the middle section and allows vapor to flow from the middle section to the upper section. A vapor and liquid barrier blocks both the flow of both vapor from the lower section to the middle section and the flow of liquid from the middle section to the lower section. Vapor conduits allow vapor to flow from the lower section to each of the middle portions in varying amounts. Also processes for separating a feed stream.

摘要： An annular divided wall column for the cryogenic rectification of air or constituents of air is provided. The annular divided wall column includes a first annular column wall and a second annular column wall disposed within the first annular column wall to define an annulus column region and an interior core column region. The present annular divided wall column further includes structured packing elements disposed within at least the annulus column region as well as a ring-shaped cantilevered collector; and a ring-shaped distributor disposed in the annulus column region above or below the plurality of structured packing elements. The thermal expansion and contraction of the second annular column wall in a radial direction and in an axial direction is independent of the thermal expansion and contraction of the first annular column wall in the radial and axial directions.
