LI Jingyao, GONG Maoqiong, TANG Qixiong, et al. Design of coiled-wound heat exchanger in small plant of LNG[J]. CIESC Journal, 2015, (S2): 108-115.DOI: 10.11949/j.issn.0438-1157.20151061.
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.
