METHODS FOR MEASURING A COMPONENT OF A CLEAR SEPARATION UNIT OF THE ACETIC ACID REACTOR AND TO CONTROL A ACETIC ACID PRODUCTION PROCESS

摘要

Process to produce acetic acid this invention refers to a method by determining the characteristic of one or more components at a stage in a process of acetic acid production using Raman spectroscopy. The process includes providing a feed stream comprising multiple components in a seperation unit,One of the components being acetic acid,The separator unit separating the feed current into two or more output currents having a different composition from each other,And measuring a characteristic of one or more of the components by spectroscopy analysis of Raman.
