Detecting Early Process Breakthrough in Heat Exchangers

Detecting Early Process Breakthrough in Heat Exchangers
Here's an example of a heat exchange breakthrough on a plant schematic and and where to place sensors.

Heat exchangers are used throughout many industrial plants to cool and convert steam into condensate. Condensate contamination is very costly and affects efficient operation of the plant, or even worse, the contamination can cause environmental pollution.

Monitoring the conductivity of the condensate leaving the heat exchanger is a reliable method to ensure the heat exchanger is functioning properly and no "breakthrough" of the process water has occurred during the cooling process.

Typical installations usually include multiple conductivity sensors tied into several large panel-mount conductivity transmitters in a cabinet. This requires an inordinate amount of space in the cabinet and wiring. Memosens® smart digital technology provides a maintenance-free solution for the operators.

When using a SE 615 Memosens conductivity sensor, any contamination within the condensate water will be detected. The SE 615 sensor is installed downstream from the heat exchanger where the process is much cooler.

With the M4 Knick Memosens solution, fast and reliable conductivity measurement is tied into the compact (0.5" wide) DIN rail mounted MemoRail transmitter which frees up space within the control cabinet and eliminates the excessive amount of wiring. Read more details about it in the M4 Knick Application Solutions Magazine.
