Introduction

在如今能源密集型社会，精馏基本原理没有改变，精馏的重要性和地位也同样没有改变，改变的是精馏有了更广泛的应用范围和更深入的分析方法，以及稳态设计和动态控制的改善。在本书的第一版出版后的七年时间里，许多新的概念和应用已得到开发并发表于文献中。

随着热耦精馏塔（Petlyuk）在工业应用中得到广泛的推广，本书增加了复杂精馏塔的设计和控制章节。在新章节中使用动态模拟的方法定量探讨了快速瞬时响应对主工艺造成紊乱和故障的安全问题，并概述了如何采用更多的构造法进行控制结构的选择，以便给大量的可替代控制结构的分类整理提供帮助。一个简单精馏塔都存在多达120种可替代控制结构，所以需要将其降低至一个可操作的数目以便于进行稳态和动态性能的比较。

随着工业生产中对二氧化碳捕集塔的关注日趋增多，所以本书新增了研究低压胺液吸收／解吸系统和高压物理吸附吸收／解吸系统的设计和控制章节，新版本的Aspen软件已经增加了这个功能和特性。化工工厂的发展伴随着电厂或绿化能源（风能或太阳能）的发展，大大提高了精馏塔操作弹性的重要性。本书新增了一个章节讲述如何有效地处理这些操作弹性相关的精馏塔控制结构。

笔者希望本书的新版是实用且通俗易懂的。本书所覆盖的内容是非常简易和实用的，因此，书中所载内容有很大的实际应用价值。笔者衷心祝愿您在精馏设计和控制的事业上好运，您会发现从事精馏设计和控制相关的工作非常具有挑战性，同时也是有趣的。
