In general, different refinery processes require different qualities of water:
- Cooling water generally needs to be able to resist corrosion and reduce organic slimes and sediment formation.
- Circulating water systems often have fouling and corrosion problems without chemical treatment. Boilers and cooling water, for example, are treated with amines to neutralize the acidic build-up that may damage the facility.
- Boiler feed water makeup requires higher quality water to prevent excessive corrosion and scale formation. Although the modern system may not even need annual cleaning, it is important to check impurities in boiler water to make sure it delivers satisfactory results.
