Improved Techniques for Cooling Water Corrosion Control

water treatment for corrosion control

certain gases, principally oxygen,o , and carbon dioxide, co , dissolved in water accelerate its corrosive properties. the rate of corrosion is approximately in prportion to the quantity of gas dissolved. the removal of gases from water, as practiced in steam station, is effected by mechanical and thermal treatment , by addition of chemicals, or by combinations of these processes, the most wide...

Pilot-scale cooling tower to evaluate corrosion, scaling, and biofouling control strategies for cooling system makeup water.

Pilot-scale cooling towers can be used to evaluate corrosion, scaling, and biofouling control strategies when using particular cooling system makeup water and particular operating conditions. To study the potential for using a number of different impaired waters as makeup water, a pilot-scale system capable of generating 27,000 kJ∕h heat load and maintaining recirculating water flow with a Reyn...

Multilayer Nano Films for Corrosion Control

Nano films consisting of an alternating sequence of positively and negatively charged polyelectrolytes have been prepared by means of the electrostatic layer-by-layer (LBL) sequential assembly technique on treated and untreated mild steel wires. Inhibitor was encapsulated between cationic and anionic polyelectrolyte nano films. This paper mainly focuses on the effect of these nano-films of poly...

INVESTIGATION INTO SYNERGISTIC EFFECT OF MOLYBDATE AND PHOSPHATE AS AN INHIBITOR FOR MILD STEEL CORROSION PREVENTION IN SIMULATED COOLING WATER

The synergistic behavior of molybdate and phosphate ions in mitigating the corrosion of mild steel in simulated cooling water was evaluated performing potentiodynamic polarization and impedance spectroscopy tests. Phosphate and molybdate showed a synergistic effect on corrosion inhibition of steel in simulated cooling water. The observed reduction in anodic and cathodic current densities could ...
