Abstract:

Plate-fin heat exchanger, as the core equipment in the cryogenic separation process of ethylene plant, can realize heat exchange between multi-strand materials. Therefore, it has large volume, complex structure and long purchasing cycle, and is mainly imported from abroad. Once this equipment leaks, the manufacturer will be unable to supply a new one in a short period of time, and the production plant will have to be shut down for a long time. Localized large plate-fin heat exchanger applied in the cryogenic section of ethylene plant has the same performance as the imported equipment, and it has the advantages of short purchasing cycle, quick after-sale service and remarkable saving of funds, showing ideal service effect.
