Analytics for Chlor-Alkali Production

This guide looks at how to increase chlorine production efficiency, reduce sensor maintenance efforts and prevent corrosion, while using equipment that resists harsh conditions. It also introduces the METTLER TOLEDO InPro 4850i pH sensor that can withstand the harshest chlor-alkali processes. Read more

Accurate pH measurement is critical in chlor-alkali processes, but the conditions are very tough on conventional pH sensors. Using a sensor designed specifically for chlor-alkali applications, Evonik Industries has cut sensor maintenance by 80%. Read more

This case study describes how at a US chlor-alkali site, pH and ORP measurements in harsh conditions were extremely problematic. METTLER TOLEDO was given the opportunity to show that we could make these measurement points more reliable, less expensive and safer to operate with InPro 4850i sensors. Read more

A combination of elevated temperatures, the presence of oxidants, and highly sensitive sensor output signal makes reliable pH measurement in the chlor-alkali process very challenging. This application note reviews these problems in relation to membrane cell chlorine production and explains how the InPro 4850i pH sensor solves all the measurement issues. Read more

This white paper explains: Membrane cell chlorine production, problems with conventional pH electrodes, pNa/pH technology, measurement challenges, plug and Measure – fast and simple start up. Read more
