Plate&Shell Heat Exchanger in Petrochemical And Refining Industries

Application Description: In ethylene cracking and ammonia synthesis plants, high-temperature process gases (such as cracking gas and synthesis gas) need to be cooled. Due to their efficient heat transfer performance, plate and shell heat exchangers can cool high-temperature process gases with a relatively small heat transfer area while simultaneously recovering a large amount of high-temperature potential heat energy, resulting in significant economic benefits.

Advantages: High throughput, low pressure drop, and high heat transfer efficiency. They can replace multiple shell and tube heat exchangers in series, saving space and investment.

Application Description: In catalytic reforming units, heat exchange is required between the high-temperature reaction products and the feedstock. This is a typical high-temperature, high-pressure operating environment.

Advantages: Plate and shell heat exchangers can withstand high temperatures and high pressures, and their narrow gap design reduces fouling tendency compared to shell-and-tube heat exchangers, ensuring long-term high efficiency.

Applications: Applications such as condensation at the inlet of high-pressure air coolers in hydrocracking and hydrotreating units, or as reboilers.

Advantages: The plate structure can withstand extremely high pressures (up to 8.0 MPa or higher), and the condensation efficiency is far superior to that of standard shell-and-tube condensers.
