Abstract

As a critical component of the ethylene plant cracking gas compressor, interstage coolers play a key role in enhancing equipment stability, efficiency, and safety. This article focuses on the characteristics of ethylene processes and industrial features, comprehensively analyzing corrosion-inducing factors such as process media, equipment design, and operating conditions. Emphasizing the importance of addressing interstage cooler corrosion, it clarifies the underlying logic of anti-corrosion measures. By implementing effective strategies in areas such as media treatment, operational optimization, and monitoring systems, the article proposes establishing a robust framework to address corrosion issues in cracking gas compressor interstage coolers, resolving problems like equipment leakage and declining heat transfer efficiency, thereby promoting the transformation and upgrading of ethylene production systems.
