Linear transfer line exchanger for ethylene plants

Rapidly cools furnace effluent in ethylene plants to optimize performance and prevent material degradation, ensuring efficient downstream processing.

Rapidly Cools and Quenches Cracked Gas

The BORSIG Linear Transfer Line Exchanger efficiently addresses the cooling and quenching requirements of ethylene furnace effluent. Utilizing its patented linear quencher design, it incorporates linearly arranged double pipe elements directly coupled to each furnace radiant coil outlet. This eliminates the need for complex fittings, minimizing fouling and erosion. Commonly applied in ethylene production, it supports processes like quenching and separation of cracked gas into ethylene, ethylene glycol, and polyethylene. With its compact, modular design, it enables easy integration into continuous operations and offers customizable configurations for single or twin-leg setups. The design ensures a low-pressure drop and reduced residence time, enhancing operational efficiency. Constructed for durability, it allows online decoking and includes maintenance-friendly features, fitting seamlessly within chemical and petrochemical industry environments. BORSIG’s extensive experience with over 6,000 installations worldwide affirms reliability and robust performance in challenging conditions.
