Description

Verfahren zur Abtreibung von Dämpfen 13ei der Abtreibung von Dämpfen aus Flüssigkeiten ist es hekannt, einen Teil der l>ei der Kondensation der gegel>enenfal Is verstärkten Dämpfe freiwerdenden Wärme unter Aufxvendung von Verdichtullgsenergie zur Erzeugung des zur treihung erforderlichen Dampfes aus der Nbtriel)skolonne verlassenden Flüssigkeit zu verwenden. Hierdurch können erhebliche Wärmeersparnisse erzielt werden. Die praktische Durchführung dieser NVärmerückführung stößt jedoch auf Schwierigkeiten, wenn die aus der Abtriebssäule ablaufende Flüssigkeit Eigenschaften hesitzt, welche sie für die Dampferzeugung in einem mit kleinstem Temperaturgefälle arbeitenden Dampferzeuger ungeeignet machen. Dies ist z. B. der Fall, wenn sich aus der Flüssigkeit Stoffe ausscheiden, welche an den Heizflächen Ansätze bilden, oder wenn die Flüssigkeit heim Verdampfen stark schäumt. Nach der Erfindung werden diese Schwierigkeiten dadurch beseitigt, daß der zur Abtreibung erforderliche Dampf nicht wie üblich aus der die Abtriebskolonne verlassenden Flüssigkeit, sondern aus Wasser, welches die Abtriebskolonne nicht durchströmt hat, erzeugt wird. Dieses Wasser kann nach einem der in der Dampftechnik üblichen Verfahren aufbereitet sein. Um den Wärmeverbrauch zur Erwärmung des Wassers auf die Verdampfungstemperatur zu vermindern oder zu vermeiden, ist es zweckmäßig, Wasser zu verwenden, welches von seiner vorherigen Verwendung her bereits Wärme enthält, vorzugsweise erwärmtes Kühlwasser oder Kondensat. Wenn die Temperatur des zur Verfügung stehenden Wassers höher ist als die Verdampfungsternperatur bei der Erzeugung des Abtriebsdampfes, tritt bei der Entspannung des Wassers eine zusätzliche Dampfbildung ein, welche die Menge des insgesamt gebildeten Dampfes in erwünschter Weise erhöht.Procedure for aborting vapors 13in the abortion of vapors It is known from liquids to take part in the condensation of the gel enfal Is increased vapors released heat with the use of compression energy to generate the steam required for the drive from the Nbtriel) skolonne Liquid to use. This allows considerable heat savings to be achieved. The practical implementation of this heat recovery, however, encounters difficulties if the liquid draining from the stripping column has properties, which they for steam generation in a working with the smallest temperature gradient Make the steam generator unsuitable. This is e.g. B. the case when out of the liquid Eliminate substances that form deposits on the heating surfaces, or when the liquid foams strongly after evaporation. According to the invention, these difficulties are eliminated eliminates the fact that the steam required for abortion does not come out of the die as usual Stripping column leaving liquid, but from water, which the stripping column has not flowed through is generated. This water can after one of the in the steam technology usual procedures. About the heat consumption to heat the water to reduce or avoid the evaporation temperature, it is advisable to To use water which is based on its previous use already Contains heat, preferably heated cooling water or condensate. When the temperature of the available water is higher than the evaporation temperature the generation of the steam, an additional one occurs when the water is expanded Steam generation, which increases the amount of steam generated in total Way increased.

Zur Verbesserung des Wärmeüberganges in den Abtriebsdampferzeuger ist es von Vorteil, die Wassergeschwindigkeit an den Heizflächen möglichst groß zu machen. Dies geschieht zweckmäßig durch Umpumpen des Wassers.To improve the heat transfer in the driven steam generator it is an advantage to keep the water velocity on the heating surfaces as high as possible close. This is conveniently done by pumping the water.
