乙烯装置大型板翅式换热器国产化应用

Application of Localized Large Plate-fin Heat Exchanger in Ethylene Plant

板翅式换热器作为乙烯装置深冷分离工艺流程中的核心设备,可实现多股物料之间的热量交换,因此体积大,结构复杂,采购周期长,主要为国外进口设备。一旦该设备出现泄漏,厂家短期内无法及时供货,生产装置将面临长期停工。大型板翅式换热器国产化在乙烯装置深冷部分的应用,具有与进口设备相当的使用性能,采购周期短,售后服务迅速,节约资金等优势,使用效果理想。

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.
