Scale and Corrosion Inhibitor for Recirculating Cooling Water
Nowadays, all power plants, steel mills, oil refineries, fertilizer plants and other enterprises have to use circulated cooling water. Because enterprises use groundwater, surface water, or even recycled water, as circulating water, which have significant differences in hardness, alkalinity and those anions & cations, corrosion and scale trends are also different. Although polymers and organophosphorics can also be used as water treatment chemicals, the performance of monomers was not as good as compound chemicals, the built chemicals will creat synergies for each monomers, thus achieving the better effects. Based on many experiments and researches, we developed the corresponding scale and corrosion inhibitors for different water quality.
Soft water (low hardness water): IR-682(D) can be used. IR-699 is for extremely soft water and purified water system. In closed system is also mainly soft water. Whereas, IR-268B is mainly used due to its features.
Medium Hardness Water: IR-619(B), IR-628(B), IR-604
This is just for reference. The chemical types and dosage for different water quality should be determined by calculation.
Water Quality Classification (by hardness)
1. As for circulated cooling water system in the central air-conditioner, the chemicals should be chosen according to water quality. IR-268B can be used in chilled water system.
2. The chemical selection of all circulated water depends on water quality. Strictly speaking, it is unscientific to use those chemicals marketed as “specially for circulated cooling water from power plant and steel mill”. At present, there is no commonly used chemicals. We have to clarify the water quality and corrosive or scale types at first, and then choose the correct chemicals in order to achieve economical and excellent effect. That is, the economical usage of water treatment chemicals depends on water quality rather than factory types.
