Chemical cleaning is an effective method for addressing corrosion and scaling issues on the inner walls of the overhead air coolers in petrochemical plants
Thread Content
In petrochemical units, the medium inside the top air coolers is usually oil and gas. Over time, this oil and gas on the inner walls of the equipment can cause corrosion of the metal surface as well as the formation of rust, which affects the equipment’s service life and its heat exchange efficiency. Corrosion can cause leaks in the heat exchange tubes, affecting the safe operation of the equipment. Due to the structure of the equipment, mechanical cleaning methods are not effective; they are time-consuming and labor-intensive. And the chemical cleaning method yields very good results. It is recommended to shut down the unit for maintenance and cleaning. The figure below shows the effect of chemical cleaning on the overhead cooler of a vacuum distillation tower at a petrochemical company.
Chemical cleaning methods can effectively address the corrosion and scaling issues on the inner walls of the overhead air coolers in petrochemical plants, thereby improving the safe operation of the equipment and its heat exchange efficiency. .
