REAL-TIME ONLINE DETERMINATION OF CAUSTIC IN PROCESS SCRUBBERS USING NEAR INFRARED SPECTROSCOPY AND CHEMOMETRICS

摘要

monitoring the concentration of caustic in the caustic scrubber and / or a process, an apparatus for controlling , and the system is described herein. In various aspects, the process and apparatus, and a system comprising the on-line method for determining the concentration of caustic in the scrubber process, in which the probe is connected to the spectrometer; It collects absorption data having a wavelength range of 1000 to 2000 nm. In a further aspect, the techniques used to track the caustic scrubber and the recharge process. This summary is to be intended as a research tool for the search object in the specific technical field, and are not intended to limit the invention.
