Analysis on corrosion causes of heat exchangers of circulating cooling water system and improvement measures thereof
In petrochemical production,heat exchanger is an important part of the system.As long-term continuous operation of circulating cooling water system,abnormal operation and management can lead to heat exchanger and pipe corrosion;as severe cases,it can affect normal industrial production and cause economic losses.Based on engineering examples and combined with on-site operational circumstances,the causes of corro-sion in heat exchangers were analyzed with relevant improvement measures and suggestions proposed at the same time.After restart the circulating cooling water system,there was no obvious corrosion or scale formation in the heat exchangers,which showed good operation effect,and provided experience reference for the operation of sim-ilar projects.
