Aspen plus简介与经济评估中的应用实例PPT课件

1、Reporter : 评估论证会用到 甲醇生产的1.ASPEN（Advanced System for Process Engineering）其作为流程模拟与优化软件，不仅能模拟不同的工艺流程并给出详细的热量和物料衡算结果，而且还能估计设备大小和提供投资、操作费用及进行经济可行性的初步估算，最新版本为Aspen One V7.2。 2.新版本的Aspen Plus 模块可以方便的调用NIST数据库进行物性查询和估算。总体而言，Aspen Plus模拟是基于静态的，需使用Dynamics才能完成相应的动态模拟。另外，使用该模块的灵敏度分析以及优化子功能，可以方便的进行工况变化分析和寻优。3.

2、Exchanger Design and Rating 模块可以对各种类型的换热器进行设计和模拟，并对换热网络做进一步的优化分析。4.Economic Evaluation模块包括Aspen Process Economic Analyzer、Aspen In-Plant Cost Estimator、Aspen Capital Cost Estimator这三个组件，对于旧版本的Aspen中，该模块名为Aspen Icarus Process Evaluator（Aspen IPE） 。这个模块除了作为独立的组件使用外， 还在内置Aspen Plus中使用，可用于：1）进行设备的精确尺寸和费

3、用估算；2）进行初步的机械设计；3）估算购置和安装费用、间接费用和总投资、完成工程设计-订货-建设的计划日程表和利润率分析。图为NREl进行技术经济评价流程，可以看到：物料衡算与能量衡算会用到Aspen plus；设备估算会用到Icarus（现为Aspen中的economic evaluation模块）第一步：将实际的工艺流程转化为软件中的模块流程（红线为QQ截图临时添加，原料气经压缩换热进入反应，产物冷却后分离） 甲醇生产的 甲醇生产的 甲醇生产的 甲醇生产的2021/3/912输出结果的表格形式甲醇合成分离Stream ID123COMPOUTCOOL-OUTFEEDMETHANOLOUT
