The tube bundle of the overhead air cooler in petrochemical plants achieves good results through chemical cleaning

2026-03-25View Original

Thread Content

The image below shows the tube bundle of the overhead cooler in the atmospheric and vacuum distillation tower of a petrochemical company. Corrosion of the oil and gas at the tower top has caused a large amount of rust to form on the inner walls of the tube bundle, thereby affecting the cooling efficiency of the overhead cooler. During the maintenance period, the tube bundle was chemically cleaned. The following flange connection holes show the comparison before and after cleaning. Using it after cleaning improved the cooling efficiency of the air cooler.
