2、定,所以在計(jì)算過(guò)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(guò)這次設(shè)計(jì)使我認(rèn)識(shí)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(jué)得自己在綜合所學(xué)相關(guān)知識(shí)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,weshouldbemo
