Title (EN) REACTION CONTROL IN ACETIC ACID PROCESSES
(FR) RÉGULATION DE LA RÉACTION DANS DES PROCESSUS DE PRODUCTION D'ACIDE ACÉTIQUE
Abstract:
(EN) The present disclosure provides for a method for measuring the concentration of one or more components in a feed stream or reactor mixture of a process for producing acetic acid by both infrared and Raman spectroscopic analyses. In some embodiments, at least one feed stream comprising water is adjusted in response to the measured concentration of one or more components.
(FR) La présente invention concerne un procédé pour mesurer la concentration en un ou plusieurs constituants dans un flux d'alimentation ou un mélange de réacteur d'un processus de production d'acide acétique par des analyses spectroscopiques Raman et infrarouge. Dans certains modes de réalisation, au moins un flux d'alimentation comprenant de l'eau est ajusté en réponse à la concentration mesurée d'un ou de plusieurs constituants.
