Why do you need to control traces in Chlorine production?
At the different steps of the chlorine alkali process, some gas components can be found at trace level.Their concentrations can fluctuate over time and are depending on process parameters.
Species like O2, CO2, H2O are tracked in the chlorine gas matrix to insure the efficiency of the production process, and H2 is measured to avoid the explosion of the installation.
Optical Feedback Cavity Enhanced Absorption Spectroscopy
The ProCeas® is an enhanced TDL analyzer. It uses the patented OFCEAS technique, based on extractive absorption spectroscopy.
This laser based technology is able to measure directly gases down to ppb levels of concentration, with an unforeseen quality of measurement in terms of accuracy and repeatability.
OFCEAS is also the only laser technique to measure directly hydrogen down to 3ppm, giving a real time measurement of H2 at startup with up to 10 measures per second.
Unique sampling system
ProCeas® is combined with a specific sampling system using only components compatible with the aggressive chlorine gas. Using no stainless-steel tubes and no pump. But composed of tubbing and connections in PVDF and PFA. Our long-term experience in the industry allowed us to optimize our sampling to measure in dry and wet chlorine.
ProCeas® has an integrated self-calibration of the measurement system, featuring no zero and span drift over time. ProCeas® is able to analyze a large range of gases with limited maintenance costs.
