White Paper: pH And CO2 Determinations Based On Power Plant Conductivity Measurements

By David M. Gray

With the decrease in personnel overseeing power plant cycle chemistry today, greater reliance on on-line instrumentation can be a necessity. The calculated pH approach can be of further help in this regard because conductivity sensors require much less maintenance than pH sensors.

This work describes some of the improvements in instrument reliability, ease of use, and capabilities that raise confidence in these on-line measurements.
