Industrial plant encrustations: causes and problems

The increasing scarcity of “fresh” water for industrial use makes brackish water necessary. The concentration of “encrusting” salts in these water sources causes the frequent formation of compact crystalline encrustations that primarily affect the efficiency of the heat exchange equipment, forcing a stop in cleaning or chemical washing.

Incrustations treatment of industrial plants

Chemical preventive treatments prevent the incrustations formation through non-stoichiometric (“threshold”) mechanisms that interfere with the crystallization of insoluble salts. Those raise their maintainable concentrations in the water circulating (Phosphonates, Polyphosphates, some types of acrylic polymers or copolymers).

Celko Chemical has made enormous progress in this field, with the development of some exclusive products based on combinations of a new category of polymers, achieving unprecedented efficacy at extremely low dosages.

Celko Chemical plant incrustations solutions

Thanks to these new technologies, Celko Chemical is now able to:

• Manage cooling water at higher concentrations, with net saving water and treatment costs
• Inhibit precipitation even in murky waters and in severe encrusting conditions, even at high skin temperatures and alkaline pH
• Prevent the incrustations formation downstream of the injection of the milk of lime, even in the flue gas desulphurization plants (Absorbers) of the Thermoelectric Power Plants
• Prevent depositions even in water/ash mixtures up to the ratio of 50:50.
