aspen plus专业软件实训题目加答案

1、专业软件实训上机报告要求上机报告一、利用Flash2模型，以灵敏度分析为工具，模拟CO2在水中的溶解度与温度的变化曲线（压力1atm），其中起始温度为学生本人的学号最后两位，终点温度为80。并以抓图的方式把“stream”、“blocks”、“sensitivity”的“input”中输入的内容粘贴到Word中，并给出CO2水的溶解度随温度变化的Plot图。（注：物性方法选NRTL）上机报告二、利用Flash2模型，以灵敏度分析为工具，模拟绝对湿度一定时，空气的露点温度（压力1atm），其中绝对湿度为学生本人的学号最后两位除以100（如学号最后两位为15，则绝对湿度为0.015Kg水/Kg空气

2、）。并以抓图的方式把“stream”、“blocks”、“sensitivity”的“input”中输入的内容粘贴到Word中，并给出结果（即绝对湿度为*时空气的露点温度为*）。（注：物性方法选NRTL）上机报告三、利用DSTWU模型，模拟苯甲苯对二甲苯异丙苯的简捷计算，其中进料为饱和液体，压力1.0atm，组成依次为0.3、0.3、0.3、0.1（摩尔分率），流量为学生学号后两位（单位为kmol/sec）；苯为LK，回收率98%，对二甲苯为HK，回收率为2%；塔板压降0.05kPa，塔顶压力0.9 atm，塔底压力1.1 atm。以三线表给出“stream”和“blocks”的结果，其中“s

3、tream”应给出all和Full的结果。（注：物性方法选NRTL-RK）上机报告四、根据上题结果，利用RacFrac模型对结果校核（操作回流比为最小回流比的1.5倍）。给出温度塔盘、组成（汽液）塔盘、流量（汽液）塔盘的关系曲线图。并以三线表给出“blocks” 中“Results Summary”的“Summary”、“Blance”、“Split Fraction”结果。上机报告五、在上题基础上，对筛板式塔盘进行设计计算，然后根据结果，进行校核计算。将两种计算结果以三线表的形式给出，即“Tray Sizing”、“Tray Rating”的“Results”和“Profiles”。上机报告

4、六、利用RacFrac模型，模拟甲烷乙烷丙烷正丁烷正戊烷正葵烷的气体吸收过程，其中原料气进料温度50，压力5atm，组成甲烷0.8、乙烷0.1、丙烷0.05、正丁烷0.03、正戊烷0.02（摩尔分率），进料流量为学生学号后两位（单位为kmol/sec）；吸收液进料温度50，压力5atm，组成正戊烷0.01、正葵烷0.99（摩尔分率），进料流量为学生学号后两位的两倍（单位为kmol/sec）。以三线表给出“blocks”中“Results Summary”的“Summary”、“Blance”、“Split Fraction”结果。（注：物性方法选NRTL-RK）上机报告七、上题中，若尾气中丙烷

5、的组成为0.001（摩尔分率），则吸收液用量为多少。利用“Design Specs”和“Vary”进行计算。以抓图的方式把“Design Specs”的“Specification”、“Components”、“Feed/Product Stream”的内容，以及“Vary”的“Results”粘贴到Word中。上机报告八、利用HeatX模型，模拟水（压力1atm，温度20，流量10tonne/hr）冷却热空气（压力1atm，温度120，流量为学生学号后两位的开平方tonne/hr）的计算。换热器“Setup”采用“Shortcut”和“Design”，出口温度110。以三线表给出“Strea

6、m”的“Results”（“Display”：All Stream，“Format”：Full）。并给出“blocks”中“Thermal Results”下的所有结果，指出换热器的面积和对数平均温度值。（注：物性方法选IDEAL）上机报告九、上题中，若换热器“Setup”采用“Hetran-Rigorous”和“Design”，出口温度110。指出两种不同情况下，“blocks”中“Thermal Results”下结果的异同，并以三线表给出“blocks”中“Hetran Thermal Results”下的所有结果。上机报告十、利用ASPEN Plus的“B-JAC”模块，模拟计算20的

7、水，将70的煤油冷却至50的过程，冷热流体操作压力均为1atm，冷流体流量为10tonne/hr，热流体流量为（10+学生学号后两位）tonne/hr。以普通表格形式给出“Thermal Summary”下的所有结果。并以“Export to DXP”将“Mechanical Summary” 下“Setting Plan & Tubesheet Layout”的换热器图输出，并插入到Word中。注意：1. 报告封面打印必须用A4纸张，标题写“专业软件实训上机报告”，一号，黑体，加粗。写明姓名、班级及学号（标题下方，三号宋体加粗居中）。2. 报告正文一律使用标准简化汉字，采用Word文档格式，

8、用计算机打印在A4（2129.7）纸上。采用单面打印，右侧装订。3. 每题的标题（如上机报告一、上机报告二）以三号宋体加粗居左；正文基本用字为小四号宋体，数字及英文字体均为Times New Roman，字符间距：标准，行距：单倍。页面上、下、左、右页边距的设定分别为：3.0、2.5、3.0、2.0。4. 除封面不编排页码外，报告正文部分请编排页码，起始页码为1，页码格式为“第*页 共*页”，字体用五号宋体，数字用Times New Roman。专业软件实训上机报告班级：化工102班姓名：曾懿学号：1011034044上机报告一1.1 Stream中的input:1.2 Block中的inpu
