The present invention relates to a method for monitoring flow based separation processes and/or flow analysis processes for analysing mixtures of components. The method comprises the steps of: obtaining measurement signals by measuring process conditions at a plurality of positions throughout the system; applying signal processing to the measurement signals, said signal processing comprising multivariate data analysis for condensing the plurality of measurement signals to a smaller number of main signals being non-correlated; logging said main signals; and displaying said main signals versus time, where changes of said system conditions are indicated by one or more of the displayed main signals. According to the invention there is also provided an apparatus for carrying out the method as well as a use of the method.
La présente invention concerne un procédé de surveillance de processus de séparation à base de flux et/ou de processus d'analyse de flux destiné à l'analyse de mélanges de composants. Ce procédé consiste à: obtenir des signaux de mesure par la mesure d'états de processus dans plusieurs positions à travers le système; à appliquer le traitement des signaux aux signaux de mesure, ce traitement des signaux consistant à analyser des données multivariable aux fins de condensation de la pluralité de signaux de mesure en un plus petit nombre de signaux principaux non corrélés; à enregistrer ces signaux principaux; et à afficher ces signaux principaux versus temps, là où des changements de ces états de système sont indiqués par au moins un des signaux principaux affichés. L'invention concerne également un appareil permettant de mettre en oeuvre le procédé, ainsi que l'utilisation de ce procédé.
