Description

Verfahren zur fortlaufenden Messung von kondensierbaren Gasen und Dämpfen in Gasgemischen. In dem Patent 329386 ist ein Verfahren zur fortlaufenden Messung von absorbierbaren Gasen und Dämpfen in Gasgemischen beschrieben, wobei die zu messenden Bestandteile durch Absorption zwischen zwei Drosselstellen entfernt und ihr Anteil am Gesamtvolumen des Gemisches durch Messung des Druckunterschiedes mit parallel geschalteten Drosselstellen ohne Absorption fortlaufend bestimmt wird.Process for the continuous measurement of condensable gases and Vapors in gas mixtures. In the patent 329386 is a method for continuous Measurement of absorbable gases and vapors in gas mixtures described, whereby the components to be measured are removed by absorption between two throttling points and their share in the total volume of the mixture by measuring the pressure difference is continuously determined with throttling points connected in parallel without absorption.

Es wurde nun gefunden, daß man in vielen Fällen statt der Absorption mit Vorteil eine Kondensation benutzen kann, um den zu messenden Bestandteil zwecks Erzeugung der Druckdifferenz aus dem: Gemisch zu entfernen. Die Ausführung geschieht in der Weise, daß man den in der genannten Patentschrift beschriebenen Absorptionsbehälter durch eine Kondensationsvorrichtung an sich bekannter Art, wie z. B. ein gekühltes. Rohr, Rohrbündel oder Rohrschlange usw. ersetzt, die mit einer geeigneten Einrichtung zur fortlaufenden oder zeitweisen Entfernung des Kondensats versehen ist. Dabei ist durch geeignete Wahl der Temperatur Sorge zu tragen, daß an allen anderen, nicht zu der Kondensationsvorrichtung gehörenden Teilen der Meßvorrichtung eine Kondensation vermieden wird. Liegt die Kondensationstemperatur also beispielsweise über der Raumtemperatur, so ist die ganze Vorrichtung zwischen Eingang und Ausgang der Drosselstellen mit einem Heizmantel o. dgl. zu versehen und nur die Kondensationsstelle selbst auf der erforderlichen tieferen Temperatur zu halten. Als Beispiele für die Anwendung des vorliegenden Verfahrens seien die Kondensation von Wasserdampf mit Wasserkühlung oder von Ammoniak mit Kältebädern genannt.It has now been found that in many cases instead of absorption can advantageously use a condensation to the component to be measured in order to Generation of the pressure difference from the: Remove mixture. The execution happens in such a way that the absorption container described in said patent by a condensation device of a known type, such as. B. a chilled. Tube, tube bundle or coil etc. replaced with a suitable device is provided for the continuous or temporary removal of the condensate. Included care must be taken by a suitable choice of temperature that all others do not to the condensation device belonging parts of the measuring device a condensation is avoided. For example, if the condensation temperature is above room temperature, so the whole device is between the inlet and outlet of the throttle points a heating jacket o. The like. To be provided and only the condensation point itself to maintain the required lower temperature. As examples of the application of the present process are the condensation of water vapor with water cooling or called by ammonia with cold baths.
