Abstract
Description
Die Erfindung betrifft eine Verdampfervorrichtung zur Verdampfung von einer in einem Reaktor enthaltenen Flüssigkeit mit einem Reaktor, der eine Seitenwand, eine Bodenwand und eine Heizvorrichtung zur Beheizung der Seitenwand aufweist, gemäß dem Oberbegriff von Anspruch 1. Die Erfindung betrifft auch ein Batch-Destillationsverfahren gemäß dem Oberbegriff von Anspruch 13.The The invention relates to an evaporator device for the evaporation of a liquid contained in a reactor with a reactor, a side wall, a bottom wall and a heating device for Heating the side wall, according to the preamble of claim 1. The invention also relates to a batch distillation process according to the generic term of claim 13.
Derartige Verdampfervorrichtungen werden für Batch-Destillationsverfahren oder Verdampfungen aus wandbeheizten Reaktoren eingesetzt. Die bekannten Verdampfereinrichtungen bzw. Batch-Destillationsverfahren haben den Nachteil, dass im zeitlichen Verlauf des Prozesses die Abdampfleistung ständig abnimmt. Die Abnahme der Abdampfleistung resultiert aus dem im Verlauf des Prozesses sinkenden Flüssigkeitsspiegel in dem Verdampfer, denn mit sinkendem Flüssigkeitsspiegel kann die vorhandene Wärmeübertragungsfläche nicht mehr vollständig ausgenutzt werden. Andererseits müssen vor- und nachgeschaltete Anlagenteile und Energiequellen, wie beispielsweise bauseitige Heiz- und Kühlanlagen für den Betrieb der Anlage, Wärmeübertrager wie Kühler und Kondensatoren, Rektifizierkolonnen und deren Einbauten sowie Rohrleitungen und Armaturen, für die maximale Abdampfleistung der Verdampfervorrichtung ausgelegt werden, die am Beginn des Abdampfens erreicht wird. Da die Abdampfleistung im zeitlichen Verlauf des Prozesses ständig weiter abnimmt, werden diese weiteren Anlagenteile und Energiequellen, die auf die maximale Abdampfleistung ausgelegt sind, bereits kurz nach dem Start des Prozesses im Unterlastbetrieb gefahren und arbeiten somit unwirtschaftlich.such Evaporator devices are used for Batch distillation process or evaporations from wall-heated reactors used. The well-known Have evaporator devices or batch distillation processes the disadvantage that in the course of the process, the evaporative power decreases steadily. The decrease in the evaporating power results from the in the course of Process sinking liquid level in the evaporator, because with sinking liquid level, the existing heat transfer surface can not more fully exploited become. On the other hand upstream and downstream plant components and energy sources, such as On-site heating and cooling systems for operation the plant, heat exchanger like cooler and condensers, rectification columns and their internals as well Piping and fittings, for designed the maximum evaporating power of the evaporator device which is reached at the beginning of the evaporation. Since the evaporating power in time course of the process is constantly decreasing these other parts of the plant and energy sources, which are at the maximum Abdampfleistung are designed, already shortly after the start of the process run under load and thus work uneconomical.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Verdampfervorrichtung gemäß dem Oberbegriff von Anspruch 1 bzw. ein Batch-Destillationsverfahren gemäß dem Oberbegriff von Anspruch 13 anzugeben, mit der bzw. dem während eines Verdampfungsdurchlaufs eine im Vergleich zum Stand der Technik annähernd gleich bleibende Abdampfleistung erreicht werden kann.Of the The invention is therefore based on the object, an evaporator device according to the generic term of claim 1 or a batch distillation process according to the preamble of claim 13, with the or during an evaporation pass an approximately equal in comparison to the prior art evaporative power can be achieved.
