設計說明:隨著國際石油價格大幅走高及石油產品大量消費導致生態環境的不斷惡化,各國紛紛制定相應發展計劃, 生物能源對于經濟和社會可持續發展的戰略意義日益增大。對于消費量大的有機原料乙基叔丁基醚(ETBE)來說,由C4與乙醇經裂解合成,直接或間接生產乙基叔丁基醚(ETBE),是很有誘惑力的路線。ETBE不但能提高汽油辛烷值,而且還可以作為共溶劑使用。具有較好的經濟性與安全性,ETBE的沸點較高,與烴類相混不生成共沸化合物。這樣既可以減少發動機內的氣阻,又可降低蒸發損失。因此它具有很大的市場潛力。ETBE的合成工藝在國外已經工業化,但在國內還處于小試階段,對于現在需求量比較大的中國來說,光靠進口已經很難實現了,中國又是一個能源大國,為了充分利用我國資源。現在積極開發ETBE的生產技術已經是勢在必行的了,隨著對車用燃料環保要求的提高,ETBE 的需求量將必然增加。因此, 開發ETBE 的生產技術可以有效的改善我國的能源短缺、過分依賴進口的現狀,進而充分利用我國資源,這對于長期發展有重要意義。4615
    本設計是新疆獨山子石化公司的子系統,依靠總廠產生的20萬噸混合C4與無水乙醇反應生成目標產品10萬噸ETBE,催化劑為QRE-01型大孔磺酸樹脂。其中真正發生反應的是混合C4中的異丁烯(53%)和無水乙醇(47%)。在已確定化學生產工藝和流程后,由定性階段轉向定量階段,通過對整個生產系統、生產車間,以及部分重要的生產單元進行物料衡算計算出主、副產品的產量,原材料的消耗定額、“三廢”排放量及組成,以及產品收率等各項經濟技術指標,從而定量地評述初步設計所選擇的工藝路線、生產方法及工藝流程在經濟上是否合理,技術上是否先進。 源¥自%六:維;論-文'網=www.aftnzs.live
An annual output of 100,000 tons of carbon four Ethanol ETBE process design
General description of the design
Along with the international oil prices sharply higher and oil products consumption led to the deterioration of the ecological environment, many countries have formulated the corresponding development plan, the strategic significance of biomass energy for sustainable economic and social development and increasing. For the consumption of large organic raw material ethyl tert-butyl ether (ETBE), were synthesized by C4 and alcohol by pyrolysis, direct or indirect production of ethyl tert-butyl ether (ETBE), it is tempting to route. ETBE can not only improve the octane number of gasoline, but also can be used as cosolvent. With the economy and better security, high boiling point of ETBE, and the hydrocarbon phase does not generate azeotropic compounds. This can reduce the air resistance within the engine, but also can reduce the evaporation loss. So it has great market potential. The synthesis technology of ETBE has been industrialized in foreign countries, but is still in the experimental stage in the domestic, for now the demand for larger China, rely on imports have been very difficult to realize, China is a big country, in order to make full use of our resources. Now the positive development of ETBE production technology has already been to be imperative, as the vehicle fuel to improve environmental protection requirements, demand for the ETBE will inevitably increase. Therefore, the development of ETBE technology to the status quo of China's energy shortage, excessive dependence on imports is improved effectively, and make full use of our resources, it has important significance for long-term development.
This design is a subsystem of a Dushanzi Petrochemical Corp in Xinjiang, relying on the factory produced 200000 tons of mixed C4 reacted with anhydrous ethanol production target of 100000 tons of products ETBE, catalyst for QRE-01 type Macroporous Sulfonic Acid resin. The real reaction is mixed in C4 isobutene (53%) and ethanol (47%). In the chemical production process, from qualitative stage to the quantitative stage, through the entire production system, production workshop, production unit and important for material balance calculation, the main by-product production, raw material consumption, "three wastes" emissions and composition, economic and technical indicators and product the yield of the preliminary design review, which quantitatively the selected process route, production methods and processes in the economy is reasonable, technology is advanced or not. 年產10萬噸碳四乙醇制乙基叔丁基醚的工藝設計:http://www.aftnzs.live/huaxue/20161220/1364.html
