Fossil fuel and nuclear power plants use heat exchangers to condense processed steam back into liquid form, often using ethylene glycol as a heat transfer fluid due to its high efficiency. However, if ethylene glycol leaks into the condensate stream, it can degrade into organic acids at elevated temperatures and pressures, causing acidification and corrosion issues. Early detection of pinhole heat exchanger leaks is crucial to maintain equipment integrity. Providing two-minute resolution data, Sievers M-Series On-Line TOC Analyzer allows for quick identification and mitigation of heat exchanger leaks, preventing costly equipment damage, downtime, and environmental contamination from the toxic glycol.
