【正文】 化工原理 課程設(shè)計(jì)0化工原理課程設(shè)計(jì)說明書姓名： 院系： 學(xué)號(hào)： 指導(dǎo)老師： 時(shí)間: 2022/7/1 化工原理 課程設(shè)計(jì)1前言 本設(shè)計(jì)說明書包括概述、流程簡(jiǎn)介、精餾塔、再沸器、輔助設(shè)備、管路設(shè)計(jì)和控制方案共七章。 說明中對(duì)精餾塔和再沸器的設(shè)計(jì)計(jì)算做了詳細(xì)的闡述，對(duì)于輔助設(shè)備和管路的設(shè)計(jì)也做了簡(jiǎn)單的說明。 鑒于設(shè)計(jì)者經(jīng)驗(yàn)有限，本設(shè)計(jì)中還存在許多的錯(cuò)誤，希望各位老師給予指正。 感謝老師的指導(dǎo)和參閱！化工原理
