REDUCTION OF CORROSION RATE AT THE CIRCULATING WATER SUPPLY UNIT OF THE PAVLODAR OIL CHEMISTRY REFINERY
Аннотация
One of the key tasks facing the international community of oil refineries is the development of complex approaches to improving the reliability of equipment and protecting materials from aggressive influences.
The water circulation supply system at petrochemical and gas processing enterprises is one of the main elements of the te chnological process.
In the water circulation systems of oil refining and petrochemical industries, there is a constant deposition of hardness salts from the cooling water on the surfaces of equipment and pipelines, the deposited salts, being a substrate, as a result of the vital activity of sulfate- reducing bacteria, aerobic and other microorganisms, become overgrown with biological deposits. Such deposits destroy the protective (inhibitory, oxide film) metal film, as a result of which the underclam corrosion progresses, as a result of deposition. Therefore, the development of modern methods of corrosion protection of water circulation systems of petrochemical enterprises is one of the most important problems of the industry
This article presents an analysis of the possibility of reducing the corrosion rate on the recycled water supply unit by optimizing the reagent treatment program, reducing the loss of recycled water for non-technological needs, and dismantling the bridges between the systems.
