aspenplus間歇精餾作業(yè)初稿

1、一直想用aspenplus做一個關(guān)于間歇精餾的模擬，當(dāng)開始做之后才發(fā)覺困難重重。間歇精餾和連續(xù)精餾差別比較大，面板上好多屬性的設(shè)置都變了樣，位置也改變了。還多出了夾套蒸汽加熱，間歇進(jìn)料時間設(shè)置等。iiipr-inF3wTTi1-a棗MJTFLDloEblIhcchfcpFJun-CillL加.Q|aXAJdirilLjg耳iiipr-inF3wTTi1-a棗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-
