料，是碳一化學(xué)的基礎(chǔ)產(chǎn)品，在國(guó)民經(jīng)濟(jì)中占有十分重要的地位。近年來(lái)，隨著甲醇下屬產(chǎn)品的開(kāi)發(fā)，特別是甲醇燃料的推廣應(yīng)用，甲醇的需求大幅度上升。為了滿足經(jīng)濟(jì)發(fā)展對(duì)甲醇的需求，開(kāi)展了此 24 萬(wàn) t/a 的甲醇項(xiàng)目。本設(shè)計(jì)介紹了甲醇生產(chǎn)方法中的木材干餾法，液相法和氣相法中的高、中、低壓法，從國(guó)內(nèi)外現(xiàn)狀考慮，本設(shè)計(jì)采用氣相低壓法。 本設(shè)計(jì)采用德國(guó) Lurgi 公司的甲醇合成工藝，合成塔選用該工藝中管殼式合成塔，對(duì)合成工段進(jìn)行了工藝計(jì)算，包括物料衡算及能量衡算；設(shè)備計(jì)算包括對(duì)合成塔設(shè)備選型及指標(biāo)計(jì)算。 關(guān)鍵詞： 甲 醇 合成 物料衡算 熱量衡算 合成塔 The Design of 240,000 t/a Methanol Synthesis Process Abstract:Methanol is an extremely important anic chemical raw materials,is also a fuel, it plays a very important position in the national recent years,with the development of affiliated products of Methanol,especially the use of Methanol fuel,the demand of Methanol is increasing order to meet the needs of economic development for methanol,
