Abstract:

Coiled-wound heat exchanger has a wide range of applications in the area of liquefied natural gas(LNG),air separation and rectisol process.This paper presents a design method of coiled-wound heat exchanger,and based on the method,piecewise infinite simal method is used to write programs to design coiled-wound heat exchanger.An existing heat exchanger is check calculated with the programs to verify the reliability of the design method.Meanwhile,a coiled-wound heat exchanger used in small plant of LNG is designed,which provides a reference for engineering designing of multi-stream coiled-wound heat exchangers.

Key words: LNG, coiled-wound heat exchanger, program design

摘要:

缠绕管换热器在天然气液化、空气分离、低温甲醇洗等低温领域有广泛的应用。提出一种可用于缠绕管换热器的设计方法,基于该方法采用分段微元法编写了缠绕管换热器设计程序;并运用该程序对已有换热器进行核算,验证了设计方法的可靠性;同时设计了用于小型LNG装置的缠绕管换热器,为工程上设计用于LNG装置的多股流缠绕管式换热器提供参考。
