前言

苯乙烯是一种重要的石油化工基本原料，是除聚乙烯(PE)、聚氯乙烯(PVC)、环氧乙烷(EO)以外的第四大乙烯衍生产品。其主要用于生产和制备聚苯乙烯(PS)、丁苯橡胶(SBR)、丙二烯—丁二烯—苯乙烯(ABS)树脂、苯乙烯—顺丁烯—苯乙烯嵌段共聚物(SBS)、苯乙烯—丙烯腈(SAN)树脂和不饱和聚酯等，并广泛用在电子、汽车、建筑、包装、日用轻工等领域中。

在世界上，苯乙烯的主要生产方法为乙苯脱氢法、乙苯共氧化法、甲苯为原料合成苯乙烯法、乙烯和苯直接合成苯乙烯法和乙苯氧化脱氢法等。其中，工业化的生产方法为乙苯催化脱氢法和乙苯共氧化法，两种方法所生产的苯乙烯分别占苯乙烯总产量的85%和15%。目前，国内外生产苯乙烯的主要方法是乙苯脱氢法，它又包括Lummus/UOP乙苯脱氢工艺、Fina/Badger乙苯脱氢工艺和乙苯脱氢选择性氧化工艺（Smart工艺）3种工艺。

化工流程模拟(过程模拟)技术是以工艺过程的机理模型为基础，采用数学方法来描述化工过程，通过应用计算机辅助计算手段，进行过程物料衡算、热量衡算、设备尺寸估算和能量分析并做出环境和经济评价的一门新兴技术。它是化学工程、化工热力学、系统工程、计算方法以及计算机应用技术等学科相互结合的产物，在近几十年中发展迅速，并广泛应用于化工过程的设计、测试、优化和过程的整合领域。

Aspen Plus是一个生产装置设计、稳态模拟和优化的大型通用流程模拟系统。Aspen Plus是大型通用流程模拟系统，源于美国能源部七十年代后期在麻省理工学院（MIT）组织的会战，开发新型第三代流程模拟软件。该项目被命名为“过程工程的先进系统”（Advanced System for Process Engineering，简称ASPEN），并于1981年底完成。1982年为了将其商品化，成立了Aspen Tech公司，并称之为Aspen Plus。该软件经过20多年来不断地改进、扩充和提高，已先后推出了十多个版本，成为举世公认的标准大型流程模拟软件，应用案例数以百万计。
