White Paper: If Organics Are in Your Cogen Process Water
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.
