| 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. |
