Photometric on-line monitor for total oxidants in the ports purge cascade
A proposed scheme for the continuous, on-line monitoring of the total concentration of oxidizing (fluorinating) gases in the top purge section of a gaseous diffusion cascade was evaluated using simulated process conditions in a laboratory. The scheme involves the reaction of the oxidizing gases in a sample stream with sodium chloride to produce chlorine, which is then measured with an ultraviolet photometer to yield a value for total oxidant concentration. This report describes the experimental apparatus used in studying this method and presents the resulting data and conclusions. The study found that the technique would work under some conditions, but would be troublesome and probably undependable if implemented as a real-time process monitor. During the study, it was discovered that the photometric approach could provide a measurement of total oxidant concentration without resorting to the salt reaction. 5 refs., 4 figs., 2 tabs.
