Abstract

Die Erfindung betrifft eine Vorrichtung zum Steuern des Druckausgleichs in Druckwechseladsorptionsanlagen. Sie dient zum Steuern des Druckausgleichs in Druckwechseladsorptionsanlagen. Sie wird bei der adsorptiven Trennung von Gasgemischen angewendet, insbesondere bei der Gewinnung von Sauerstoff oder Stickstoff aus der Luft. Die Vorrichtung besteht aus pneumatisch betaetigten Druckausgleichventilen und Steuerventilen, die ueber Steuergasleitungen mit den Druckausgleichventilen in Verbindung stehen. Die Druckausgleichventile sind als Doppelmembranventile ausgebildet. Waehrend des Adsorptionsprozesses in einem der Adsorber ist der Zwischenraum zwischen den beiden Membranen bei allen Druckausgleichventilen mit Steuergas beaufschlagt, wodurch diese geschlossen sind. Dagegen sind waehrend des Druckausgleiches die Druckausgleichventile nicht mit Steuergas beaufschlagt. Zu diesem Zeitpunkt wird das nicht am Druckausgleich beteiligte Druckausgleichventil durch Produktgas aus dem beim Druckausgleich den Druck abgebenden Adsorber beaufschlagt, wodurch es geschlossen bleibt.
