Data Acquisition Precision for the Chloralkali Process

The following paper focuses on data acquisition precision for equipment used to measure cell voltage in the chloralkali process and how precision is at the heart of EMOS® functionality.

To evaluate the accuracy of R2’s intelligent sensor, the MODA, a voltage source is connected to each channel of the MODA and compared against a high precision multimeter. The white paper then explains the importance of noise filtering and thermal compensation to achieve high voltage accuracy measurement in chlor-alkali plants, a key requirement to:

  • Increase plant safety
  • Detect early upcoming incidents
  • Set realistic trip limits
  • Assess individual cell condition (cell current efficiency and specific power consumption)
  • Perform selective maintenance
