Abstract

Bei der Entnahme von Gasgemischen aus einem Behälter, in dem eine flüssige Phase und eine Gasphase des Gemisches vorliegen, ändert sich bei der Entnahme die Gemischzusammensetzung der beiden Phasen derart, dass sich die schwerer siedende/n Komponente/n in der flüssigen Phase und die leichter siedende/n Komponente/n in der Gasphase anreichert, was fallweise zu Nachteilen führen kann.When withdrawing gas mixtures from a container in which a liquid phase and a gas phase of the mixture are present, the mixture composition of the two phases changes upon removal such that the heavier-boiling component / s in the liquid phase and the lighter boiling / n components in the gas phase enriches, which may occasionally lead to disadvantages.

Erfindungsgemäß erfolgt eine Entnahme des Gemisches bis zum Erreichen eines bestimmten Grenzwerts der Konzentration einer Komponente aus der flüssigen Phase. Bei Überschreiten des Grenzwerts wird der Mengenstrom der entnommenen flüssigen Phase reduziert und zugleich Gemisch aus der Gasphase, in der die leichter siedende Komponente angereichert vorliegt, entnommen. Die entnommenen Mengenströme aus flüssiger Phase und Gasphase werden anschließend miteinander gemischt. Dadurch kann die Zusammensetzung des insgesamt entnommenen Gemisches innerhalb eines vorgegebenen Konzentrationsbereiches gehalten werden.

Figure imgaf001
According to the invention, the mixture is removed until a specific limit value of the concentration of a component from the liquid phase is reached. When the limit is exceeded, the flow rate of the withdrawn liquid phase is reduced and at the same time mixture from the gas phase, in which the lower-boiling component enriched, removed. The withdrawn flow rates of liquid phase and gas phase are then mixed together. Thereby, the composition of the total taken mixture can be kept within a predetermined concentration range.
