【摘要】 液化天然气(LNG)中蕴含大量的冷能,具有很高的经济价值,国内外许多专家学者和商业机构提出了种种回收方案,但这些方案多数没有考虑合理用能。本文主要从能量和能质匹配的角度,利用火用的概念,探讨如何对LNG的冷能进行梯级利用,以期达到合理用能,使火用损失尽量减少。更多还原

【Abstract】 LNG contains a lot of cold energy,which have high economic value.Various methods to recycle the cold energy have been put forward by many domestic and foreign experts and scholars as well as business establishments.But most of the methods did not consider using the cold energy reasonably.This paper discusses how to use LNG cold energy in cascade mode on the basis of energy and quality matching and make use of the concept of exergy,so as to use the cold energy reasonably and to minimize the exergy loss.更多还原
