1、本科畢業(yè)設(shè)計(jì)說明書(40kt/a粗甲醇合成精餾工段工藝設(shè)計(jì)摘要作為化工畢業(yè)生,我們應(yīng)該較為系統(tǒng)掌握化工設(shè)計(jì)的基本程序和方法,使我們在查閱技術(shù)資料,迅速進(jìn)行工程計(jì)算,用簡潔的文字、清晰的圖表表達(dá)自己設(shè)計(jì)結(jié)果等方面的能力有所提高。這就是本次設(shè)計(jì)的目的。這次設(shè)計(jì),主要是進(jìn)行甲醇合成和精餾工段的物料和熱量衡算。進(jìn)行物料衡算時(shí),理論依據(jù)是物料平衡方程。但具體計(jì)算時(shí),由于副反應(yīng)較多,而且有些副反應(yīng)的生產(chǎn)量不確定,所以在計(jì)算過程中引用了一些經(jīng)驗(yàn)計(jì)算公式、做了一些近似處理。進(jìn)行熱量衡算的理論依據(jù)是熱量平衡式,在計(jì)算時(shí)有些物質(zhì)的準(zhǔn)確比
2、熱和汽化熱很難找到,所以用了近似計(jì)算值或是經(jīng)驗(yàn)值。本次設(shè)計(jì)雖然作了不少近似計(jì)算,引用了一些經(jīng)驗(yàn)值,但是都是嚴(yán)格按照有關(guān)文獻(xiàn)資料進(jìn)行的,所以設(shè)計(jì)結(jié)果達(dá)到預(yù)期效果。通過這次設(shè)計(jì)使我認(rèn)識到做設(shè)計(jì)計(jì)算時(shí)一定要嚴(yán)謹(jǐn)求實(shí),同時(shí)是我覺得自己在綜合所學(xué)相關(guān)知識進(jìn)行化工設(shè)計(jì)、迅速進(jìn)行工程計(jì)算等方面發(fā)展空間很大,有待于提高。關(guān)鍵詞:甲醇合成;物料衡算;熱量衡算AbstractAsachemicalgraduates,weshouldbemoresystematicallymasteredthebasicchemicalengineeri
