Corrosion Control in Circulating Cooling Water Systems – Kerui Chemical Launches New Corrosion Inhibitor Scale Inhibitor

 In industrial circulating cooling water systems, corrosion of metal materials (carbon steel, copper, stainless steel, etc.) can cause equipment leakage, production interruptions, and even safety accidents. Scaling and corrosion often promote each other. An ideal corrosion/scale inhibitor should combine inhibition, scale prevention, and dispersion functions.

Kerui Chemical (krhedp.com) has developed a series of corrosion‑scale inhibitors for different conditions:

  • Molybdenum‑based inhibitor: Suitable for high chloride, high conductivity water; forms a dense oxide film with excellent corrosion resistance.

  • Zinc‑salt compounded type: Fast film formation, especially for system pre‑film treatment and low‑pH conditions.

  • All‑organic formula: Heavy‑metal free (no chromium, no zinc), environmentally safe, suitable for plants with discharge restrictions.

Case study: In a petrochemical plant’s circulating water system, after using Kerui Chemical KR‑603 corrosion‑scale inhibitor, the carbon steel corrosion rate dropped from 0.18 mm/a to 0.03 mm/a (far better than the national standard ≤0.075 mm/a), while fouling thermal resistance decreased by 40%, saving about 15% on annual chemical costs.

Phosphorous Acid: A Chemical Raw Material with Both Reactivity and Value

 In the field of inorganic chemicals, phosphorous acid (H₃PO₃) is an important compound with unique chemical reactivity and extensive application value. Although its name is similar to phosphoric acid, their properties are significantly different. This dibasic medium-strong acid plays an indispensable role in industrial production and scientific research. In terms of basic properties, phosphorous acid appears as white or light yellow crystalline powder at room temperature, with a special garlic-like odor, a characteristic that makes it easy to identify. It has good solubility, being not only highly soluble in water but also miscible with organic solvents such as ethanol. It oxidizes slowly to phosphoric acid when exposed to air, so it should be stored in a sealed container to prevent moisture absorption. The core of its chemical properties is strong reducibility; it can react with various oxidizing agents such as silver ions, halogens, and hydrogen peroxide. For example, it can red...
