style="text-indent:25px">將使每塊精餾塔塔板上的氣液相平衡的組成發(fā)作改動。壓力升高，則氣相中的重組份削減，相應(yīng)的提高了氣相中的輕組分的濃度；液相中的輕組分含量添加，一起也改動了氣液相的分量比，使液相量添加，氣相量削減?？偟慕Y(jié)果是：塔頂餾分中的輕組分濃度添加，但數(shù)量卻相對削減；釜液中的輕組分濃度添加，釜液量添加。同理，壓力下降，塔頂餾份的數(shù)量添加，輕組分濃度下降；釜液量削減，輕組分濃度削減。正常操作中應(yīng)堅持穩(wěn)定的壓力，但若操作不正常，導(dǎo)致塔頂商品中重組分濃度添加時，則可選用恰當(dāng)升高操作壓力的方法，使商品質(zhì)量合格，但此刻液相中輕組分的丟失添加。</p><p style="text-indent:25px">精餾塔的操作應(yīng)掌握物料平衡、氣液相平衡和熱量平衡。物料平衡指的是單位時間內(nèi)進塔的物料量應(yīng)等于離開塔的諸物料量之和。物料平衡體現(xiàn)了塔的生產(chǎn)能力，它主要是靠進料量和塔頂、塔底出料量來調(diào)節(jié)的。操作中，物料平衡的變化具體反應(yīng)在塔底液面上。當(dāng)塔的操作不符合總的物料平衡時，可以從塔壓差的變化上反映出來。例如，進得多，出得少，則塔壓差上升。對于一個固定的精餾塔來講，塔壓差應(yīng)在一定的范圍內(nèi)，塔壓差過大，塔內(nèi)上升蒸氣的速度過大，霧沫夾帶嚴重，甚至發(fā)生液泛而破壞正常的操作；塔壓差過小，塔內(nèi)上升蒸氣的速度過小，塔板上氣液兩相傳質(zhì)效果降低，甚至發(fā)生漏液，較大降低了塔板效率。物料平衡掌握不好，會使整個塔的操作處于混亂狀態(tài)，掌握物料平衡是塔操作中的一個關(guān)鍵。如果正常的物料平衡受到破壞，它將影響另兩個平衡，即氣液相平衡達不到預(yù)期的效果，熱平衡也被破壞而需重新予以調(diào)整。填料塔是以塔內(nèi)的填料作為氣液兩相間接觸構(gòu)件的傳質(zhì)設(shè)備。</p><div

style="text-indent:25px">液體由塔的上部通過分布器進入，沿填料表面下降。氣體則由塔的下部通過填料孔隙逆流而上，與液體密切接觸而相互作用。結(jié)構(gòu)較簡單，檢修較方便。普遍應(yīng)用于氣體吸收、蒸餾、萃取等操作。填料層：提供氣液接觸的場所。液體分布器：均勻分布液體，以避免發(fā)生溝流現(xiàn)象。液體再分布器：避免壁流現(xiàn)象發(fā)生。支撐板：支撐填料層，使氣體均勻分布。除沫器：防止塔頂氣體出口處夾帶液體。氣體從塔底送入，經(jīng)氣體分布裝置（小直徑塔一般不設(shè)氣體分布裝置）分布后，與液體呈逆流連續(xù)通過填料層的空隙，在填料表面上，氣液兩相密切接觸進行傳質(zhì)。在化學(xué)工業(yè)中，大都精餾塔都設(shè)有兩個以上的進料板，調(diào)理進料板的方位是以進料組分發(fā)生改動為根據(jù)的。杭州新型精餾塔</p><p
