ABSTRACT
Industrial water systems play a vital role in plant operation by facilitating heat transfer via heat exchangers and condensers, and enabling boiler operations to produce steam for process and electrical power generation. In addition to minimizing deposit fouling, avoiding scale buildup, and reducing microbiological growth, corrosion control in water systems can be the most important factor to avoid premature failure of the heat exchanger, boiler, or process equipment. Desalination and geothermal systems also represent unique challenges in controlling corrosion. Unfortunately, corrosion in water systems can take many forms, and unless precautions are taken to mitigate the potential causes of metal loss in an operating system, premature failure in the form of general attack, pitting, cracking, or other specialized degradation mechanisms can create a forced outage for repairs.
