“Ex”是工程热力学中引入的一个新概念。Ex分析作为能量分析的一种新方法,与传统的能量分析——焓分析法相比,更为优越。特别是近年来Ex分析在众多的工业部门中获得了成功的应用,带来了可观的经济效益,从而引起了科技界的广泛重视。本刊拟于今年1～5期作为专论连载。其主要内容如下:一、Ex的概念及Ex值的计算;二、单元Ex的分析方法;三、系统Ex的分析方法;四、Ex分析方法在石油生产中的应用;五、Ex分析的热经济评价。
“Ex” is a new concept introduced in engineering thermodynamics. Ex analysis, as a new method of energy analysis, is superior to the traditional energy analysis—deuterium analysis. Especially in recent years Ex analysis has been successfully applied in numerous industrial sectors, bringing about considerable economic benefits, which has attracted widespread attention in the scientific and technological community. This issue is intended to be serialized as a monograph in the 1st to 5th issues this year. The main contents are as follows: 1. Ex concept and calculation of Ex value; 2. Analysis method of unit Ex; 3. Analysis method of system Ex; 4. Application of Ex analysis method in petroleum production; Economic evaluation.
