2004年甲醇的總需求與2003年一樣，據(jù)預(yù)測(cè)2005年的甲醇需求將會(huì)**增加，其原因是由于與甲基叔丁基醚無(wú)關(guān)的部門(mén)活躍起來(lái)。作出改預(yù)測(cè)的依據(jù)是計(jì)劃中有多少新增產(chǎn)能在考察期中實(shí)際投入使用，這些新增產(chǎn)能對(duì)市場(chǎng)的產(chǎn)品價(jià)格有哪些影響。國(guó)內(nèi)甲醇工藝技術(shù)我國(guó)是煤豐富的國(guó)家,甲醇原料采用天然氣和煤的較多。產(chǎn)量幾乎各占一半。生產(chǎn)工藝有單產(chǎn)甲醇和聯(lián)產(chǎn)甲醇兩種。聯(lián)產(chǎn)甲醇除在合成氨裝置聯(lián)產(chǎn)甲醇外,還可利用化工廠尾氣或結(jié)合城市煤氣聯(lián)產(chǎn)甲醇。甲醇技術(shù)發(fā)展很快,主要趨向?yàn)?①生產(chǎn)的原料轉(zhuǎn)向天然氣、烴類加工尾氣。從甲醇生產(chǎn)的實(shí)際情況核算,采用天然氣為原料比用固體為原料的投資可降低50%;采用乙炔尾氣則經(jīng)濟(jì)效果更為明顯。國(guó)際上,生產(chǎn)甲醇的原料以天然氣為主約占90%,以煤為原料只占2%。國(guó)內(nèi)以煤為原料生產(chǎn)甲醇的比例在逐步上升,這與中國(guó)的能源結(jié)構(gòu)有關(guān)。②生產(chǎn)規(guī)模大型化,單系列比較大規(guī)模達(dá)225萬(wàn)噸?年,即單系列日產(chǎn)7500公斤。規(guī)模擴(kuò)大后,可降低單位產(chǎn)品的投資和成本。③充分回收系統(tǒng)的熱量。產(chǎn)生經(jīng)濟(jì)壓力的蒸汽,以驅(qū)動(dòng)壓縮機(jī)及鍋爐給水泵、循環(huán)水泵的透平,實(shí)現(xiàn)熱能的綜合利用。④采用新型副產(chǎn)中壓蒸汽的甲醇合成塔,降低能耗。⑤采用節(jié)能技術(shù)。合成采用IC I 低壓甲醇合成催化劑。</p><div style="width:100%;text-align: center;"><img style="max-width: 640px; max-height: 320px;" alt="銅陵甲醇售后,甲醇"

隨著反應(yīng)溫度的升高反應(yīng)速度將迅速加快，因此選擇較高的反應(yīng)溫度對(duì)脫氫反應(yīng)較為有利。但溫度也不能太高，太高則消耗甲醇的副反應(yīng)也會(huì)加劇，電解銀催化劑的熔結(jié)現(xiàn)象也會(huì)加重，使其活性受到影響。所以，在一定條件下，反應(yīng)溫度還取決于催化劑的活性和熱穩(wěn)定性。因此，綜合以上因素，結(jié)合本系統(tǒng)的條件反應(yīng)溫度一般選擇在610--650℃為宜。（2）氧醇比:從生成甲醛的反應(yīng)式可見(jiàn)，增加氧量無(wú)論對(duì)氧化反應(yīng)還是對(duì)脫氫反應(yīng)都有利，但如氧量太多，則對(duì)生成碳氧化物的副反應(yīng)也有利。同時(shí)氧醇比的大小還涉及生產(chǎn)的安全性，銀法生產(chǎn)甲醛是在甲醇的范圍的上限以上進(jìn)行，即在甲醇過(guò)量空氣不足情況下進(jìn)行生產(chǎn)。因此，加熱阻火器、氧化脫氫、余熱鍋爐冷卻、廢氣鍋爐過(guò)濾、成品甲醛、噴淋吸收計(jì)量、尾氣過(guò)濾羅茨風(fēng)機(jī)、甲醇計(jì)量、高位槽、空氣氫氣輸送、蒸發(fā)、過(guò)濾、包裝。正常生產(chǎn)時(shí)，在足夠量的水蒸氣存在下，氧醇比一般取─。（3）配料濃度：配料濃度中的水大部分來(lái)自水蒸氣，水蒸氣起維持反應(yīng)溫度的作用。適當(dāng)增大原料氣中水蒸氣的量，有可能提高氧醇比，使反應(yīng)在較低的溫度下進(jìn)行時(shí)，仍得到滿意的轉(zhuǎn)化效果。但水蒸氣量不能太大，太大將影響吸收效果。。由于大規(guī)模裝置如2000M TPD 的合成塔直徑太大, 常采用兩個(gè)合成塔并聯(lián)。宿州木醇甲醇廠家</p><p style="text-indent:25px">因此國(guó)外公司的甲醇技術(shù)均集中于天然氣制甲醇.銅陵甲醇售后</p><p>
