Ethylene cracking gas cooling system
Quickly reduce gas temperatures in high-capacity ethylene plants with a robust cooling solution designed to optimize heat recovery and enhance operational efficiency in continuous production environments.
Cools and Stabilizes Cracked Gas Streams
The BORSIG “Tunnelflow” Transfer Line Exchanger efficiently cools cracked gas in petrochemical processes, particularly in ethylene production plants. Designed with a robust shell and tube configuration, it ensures smooth integration into continuous operations, handling diverse mass flows and heat duties with precision. Featuring a unique thin reinforced tube sheet design, it provides exceptional cooling performance with minimized thermal stress, reducing the need for frequent maintenance. The system allows swift blowdown via a quick-open valve and includes an optional erosion-protection shield for enhanced durability. Manufactured using 0.5 Mo material, it requires no post weld heat treatment, optimizing operational efficiency. The exchanger’s high water velocity prevents deposit accumulation, ensuring reliable long-term performance. Proven in applications ranging from ethylene glycol and polyethylene production to urea and ammonium nitrate synthesis, this equipment is a critical component for petrochemical companies needing efficient waste heat recovery solutions.
