Organic contamination in cogeneration water cycles is capable of causing process disruptions and catastrophic damage to expensive capital equipment. Key to confirming and troubleshooting organics removal is reliable on-line total organic carbon (TOC) measurement.
TOC monitoring ensures effective operation of the cycle and avoids unplanned production shutdown due to disruption in steam/heat. This white paper highlights the effects of organics and explains typical TOC measurement in cogeneration.
Organic contamination of pure power plant waters can cause a number of costly problems, including fouling of resins in make-up and condensate deionizers that requires frequent resin cleaning and replacement; break down of organics to acids that lower the pH of condensate and cause boiler and turbine corrosion; deposition onto heat exchange surfaces leading to significantly reduced efficiency; and foaming in the boiler that can increase carryover of other contaminants into the steam.
METTLER TOLEDO Thornton provides a complete portable solution for TOC and related high purity water measurements. The 450TOC delivers fast, real-time, continuous measurements, allowing the user to profile the water system rapidly. Similarly, the 4000TOCe with M300 transmitter is an on-line solution for rapid TOC measurement at any point in the water/steam cycle.
