Ethylene cracking gas cooling system

In ethylene production, cooling cracked gas rapidly is essential for preventing further reactions and ensuring optimal product quality. Engineering teams must address the challenge of efficient heat transfer while minimizing maintenance and operational complexities in high-temperature environments.

Rapid cooling for cracked ethylene gas

The BORSIG ‘Tunnelfow’ transfer line exchanger is designed to rapidly cool cracked gas in ethylene plants. This shell and tube heat exchanger features a large water volume and a robust shell around the bundle tubes. Its thin reinforced tube sheet at the gas inlet ensures efficient cooling by maintaining low material temperatures. Unique tube-to-tube sheet welded seams prevent sharp edges, enhancing durability. The guided water flow with high velocity across the thin inlet tube sheet prevents deposit formation. With options for either vertical or horizontal installation, the system supports varied mass flow and heat duty requirements. BORSIG supplies these units globally, ensuring they meet all plant-specific needs.
