How to determine whether the water used for air-cooling condensation in a compressor is circulating water?
Thread Content
Water is being discharged from the air-cooled side drain of the first stage of the air compressor, and the gas pressure is lower than that of the circulating water. How can one determine whether it is moisture from the circulating water or from the air? Can a sample analysis be conducted to identify the source of this moisture? Thank you!
Circulating water systems generally require the addition of chemicals, such as acid-base pH neutralizers, scale and corrosion inhibitors, insecticides, etc. Tests and analyses can be conducted based on the components of the chemicals used in your plant； The most common one is probably NaClO; by analyzing whether this component is present in the water components, it is possible to determine the source of the water
From a physical perspective, condensate water can be drained in a short time, while circulation water leakage is continuous.
Calculating using the relative humidity formula can serve as a reference. It can be determined by checking the air pressure dew point chart.
