Title
(DE) VERFAHREN UND VORRICHTUNG ZUM ABSCHEIDEN VON VERUNREINIGUNGEN
(EN) METHOD AND DEVICE FOR SEPARATING IMPURITIES
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT LA SÉPARATION D'IMPURETÉS
Abstract
(DE) Um ein Verfahren zum Abscheiden von Verunreinigungen aus einem Verunreinigungen enthaltenen Rohgasstrom bereitzustellen, welches eine optimale Nutzung von Abscheidemodulen ermöglicht, wird vorgeschlagen, dass das Verfahren Folgendes umfasst: Hindurchführung des Rohgasstroms durch mehrere parallel zueinander angeordnete Abscheidemodule; Ermitteln eines Annäherns, eines Erreichens und/oder eines Überschreitens eines vorgegebenen Beladungsgradmaximums eines oder mehrerer oder sämtlicher Abscheidemodule; Austauschen einzelner oder mehrerer Abscheidemodule gegen ein oder mehrere unbeladene Abscheidemodule.
(EN) In order to provide a method for separating impurities from a feed gas flow which contains impurities, which method makes an optimum utilization of separating modules possible, it is proposed that the method comprises the following: guiding of the feed gas flow through a plurality of separating modules which are arranged parallel to one another; determining that a predefined maximum degree of contamination of one or more or all separating modules is being approached. reached and/or exceeded; replacing of individual or a plurality of separating modules with one or more uncontaminated separating modules.
(FR) Le but de l'invention est de fournir un procédé pour séparer des impuretés d'un flux de gaz brut contenant des impuretés, qui permet une utilisation optimale de modules de séparation. À cet effet, ledit procédé comprend les étapes suivantes consistant à : faire passer le flux de gaz brut à travers plusieurs modules de séparation disposés parallèlement les uns aux autres ; déterminer si le degré de charge d'un ou de plusieurs ou de tous les modules de séparation s'approche d'une valeur maximale prédéfinie, atteint une valeur maximale prédéfinie et/ou dépasse une valeur maximale prédéfinie ; échanger un ou plusieurs modules de séparation contre un ou plusieurs modules de séparation non chargés.
