2、后送入高沸塔以分离出二氯乙烷，塔板数48层，要求塔顶氯乙烯回收率99.99%，二氯乙烷回收率0.01%。氯化氢与乙炔混合后进入反应器时要求其mol比为1：1.05。起始计算按100：105kmol/h计。最终得到的氯乙烯mol纯度不低于99.99%。总回收率不低于99.9%。l 选择合适物性方法l 绘制工艺流程l 绘制低沸塔、高沸塔在分离条件下的t-x-y图和x-y图l 通过灵敏度分析，判断影响条件较明显的因素，通过设计规定以及约束变量，确定合理的进料位置和其他相关参数l 确定反应器热负荷，精馏塔再沸器、冷凝器热负荷l 整理报告：报告内容要求，作业题目、物性方法以及模块选择依据、输入摘要、相关

3、物性分析图表、计算结果图表、灵敏度分析图表，重要结论、软件学习应用个人总结感想。2物性方法以及模块选择依据物系中含有水、醇、醚选用NTRL、UNIFAC、WILSON。NRTL的准确度高，常用。Mixer：把多股物流混合成一股物流，适用混合三通型、物流混合操作、增加热流或增加功流的操作。Compr：选用等熵模型Isentropic DSTWU：是多组分精馏的简捷设计模块，针对相对挥发度近似恒定的物系开发，用于计算仅有一股进料和两股产品的简单精馏塔。DSTWU模块计算精度不高，常用于初步设计，当存在共沸物时，计算结果可能会出现错误，DSTWU模块的计算结果可以为严格精馏计算提供合适的初值。Rad

4、Frac模块可对下述过程做严格模拟计算：普通精馏、吸收、汽提、萃取精馏、共沸精馏、反应精馏（包括平衡反应精馏、速率控制反应精馏、固定转化率反应精馏和电解质反应精馏）、三相（汽-液-液）精馏。RadFrac适用于两相体系、三相体系、窄沸点和宽沸点物系以及液相表现为强非理想性的物系Heater 模型用于模拟单股或多股物流，使其变成某一特定状态下的单股物流；也可通过设定条件来求已知组成物流的热力学状态。3输入摘要;Input Summary created by Aspen Plus Rel. 11.1 at 12:29:29 Thu Jan 12, 2017;Directory F:化工132谷婷
