aspenplus间歇精馏作业初稿

1、一直想用aspenplus做一个关于间歇精馏的模拟，当开始做之后才发觉困难重重。间歇精馏和连续精馏差别比较大，面板上好多属性的设置都变了样，位置也改变了。还多出了夹套蒸汽加热，间歇进料时间设置等。iiipr-inF3wTTi1-a枣MJTFLDloEblIhcchfcpFJun-CillL加.Q|aXAJdirilLjg耳iiipr-inF3wTTi1-a枣MJTFLDloEblIhcchfcpFJun-CillL加.Q|aXAJdirilLjg耳li|ryUi：ir或（ih-S:-a|iJf!Gft-4GD-iiB（：）:j翼睚CaalliiftiiaidlvcJSh-孚雨胚（D|站耳豹r-

3、定义加热方式Condenser标签页中定义冷凝的类型Reflux标签页中定义回流比或者回流量等等JacketHeating子项中定义加热介质或者设定热负荷然后是pressure/holdup选项定义操作压力和塔的压降在pressureprofileandHoldup中有两个类型Fixed和Calculator这里塔初始化是Empty选用calculatorHoldup是塔板持液量设置料再塔内的滞留量iMain然后是初始状态设置iMainInitialChargeSideDrawReceiversInitial匚onditiorrInitialdrumliquidvolumefraction;I

5、n标签页中定义结束精馏的条件当六甲基二硅氮烷的含量为0.05时结束精馏我一直在惦记着还有两个问题没解决，一个是进料的事后属于间歇进料需要设置间歇进料的时间昨天在实验室看书刚刚找到了这方面的内容-勺SatupSpe:iia-a.13ans母SiirnjlationOpticiLS涉StreamClass0-:衲Subetrs-iTisn|一_jOperatingSteps匚harigedParameters：EndConditionLocation:JackfitHeatingVDutyV在EndCondition标签页中定义结束精馏的条件当六甲基二硅氮烷的含量为0.05时结束精馏我一直在惦记着
