Paper Abstract

A commercial FT-Raman instrument has been modified for use in on-line chemical composition analysis to control an industrial distillation column. Optical fibers are utilized to allow the placement of the instrument 35 meters from the process environment. Various process probes have been tested and compared. Computational algorithms are used to develop a mathematical model which correlates spectral characteristics to composition. Predictions from the model are presented at three minute intervals to allow statistical process control of a distillation column through operator intervention. Recent application studies and probe modifications are discussed.
