Petrochemical air coolers use chemical cleaning to remove rust and scale, avoid corrosion and improve heat exchange efficiency
Thread Content
People who manage equipment in the petrochemical industry know that the gasoline air cooler at the top of the splitter tower (the outer wall is a tube bundle with fins) has a lot of rust inside the air cooler after running for a period of time. First, it affects the heat transfer effect of the air cooler ； Second, it corrodes the metal surface severely. It cannot be removed by manual mechanical methods. However, the chemical cleaning method works very well, as shown in the figure below. After cleaning, the air cooler meets the production process requirements and reduces equipment corrosion.
What chemical reagent was used to clean it?
Generally speaking, the volume of cleaning agents used in petrochemical equipment is relatively large. Considering the cost issue, the method of adding inorganic acid and corrosion inhibitor is generally used, which has the best overall benefits.
