3、產(chǎn)成本的關(guān)鍵因素之一。換熱器是化工生產(chǎn)中重要的通用熱工設(shè)備之一，管殼式換熱器以其結(jié)構(gòu)簡(jiǎn)單、牢固、操作彈性大等特點(diǎn)被廣泛應(yīng)用于工業(yè)生產(chǎn)中。 本文的研究對(duì)象是四塔甲醇精餾工藝，與傳統(tǒng)工藝相比新工藝能夠節(jié)約能量，節(jié)約軟水；但是同時(shí)新工藝增加了系統(tǒng)的藕合程度，加強(qiáng)了塔之間的關(guān)聯(lián)性，提高了系統(tǒng)對(duì)于進(jìn)料波動(dòng)的響應(yīng)的復(fù)雜性，給控制帶來(lái)了很大的難題。為了能夠?qū)崿F(xiàn)新工藝的工業(yè)應(yīng)用，對(duì)新工藝進(jìn)行詳細(xì)的研究。關(guān)鍵詞： 關(guān)鍵詞：甲醇精餾，Aspen
