【正文】 化學化工學院畢業(yè)設計 i 年產(chǎn) 1000 噸異戊烯醇生產(chǎn)工藝設計 摘要： 本課題是年產(chǎn) 1000 噸異戊烯醇的生產(chǎn)工藝設計。異戊烯醇 是合成香料、農(nóng)藥和 醫(yī)藥等產(chǎn)品重要中間體 的原料 ，也是 能 合成橡膠的重要原料。 隨著人們對異戊烯醇 合應用范圍 在不斷的 擴 大，需求量也大幅 度 上升。 本設計采用異丁烯和多聚甲醛為原料，以磷酸氫二鈉為催化劑進行 Prins 縮合反應，合成 3甲基 3丁烯 1醇 ，然后經(jīng)異構化反應生成 異戊烯醇。整個工藝包括物料衡算、能量衡算、設備設計與選型、經(jīng)濟效益與評估，并給出了 工藝流程圖，主要設備圖和車間布置圖。 關鍵詞： 異戊烯醇；異構化反應 ；工藝設計 The production design of annual yield of 1000 tons prenyl alcohol Abstract: This paper is the design and production process with an annual output of 化學化工學院畢業(yè)設計 ii 1000 tons of isopentenol. Isoamyl alcohol is an important intermediate for the synthesis of spices, pesticide and pharmaceutical products such as raw materials, but also can be an important raw material for the synthesis of rubber. Along with the people of isoprene and application scope expands, demand is also rising. This design uses isobutene and formaldehyde as raw material, with dibasic sodium phosphate as Prins condensation catalyst, synthesis of 3 methyl 3 butene 1 alcohol , and then isomerization reaction generate isopentenyl. The whole process includ the material balance, energy balance, equipment design and selection, economic benefits and evaluation, and gives the flow chart, the map of major equipment and workshop layout. Keywords: prenyl alcohol。isomerization reaction。 process design。 目錄 第 1章 綜述 .................................................................................................................... 1 前言 .......................................................................................................................... 1 異戊烯醇的性質 ................................................................................................. 1 異戊烯醇的用途 ................................................................................................. 1 異戊烯醇的市場分析 .......................................................................................... 2 原料簡述 ............................................................................................................ 3 化學化工學院畢業(yè)設計 iii 異丁烯 ..................................................................................................... 3 多聚甲醛 ................................................................................................. 3 第 2章 工藝概括 ............................................................................................................. 5 生產(chǎn)方法的評選 ................................................................................................. 5 異丁烯法 ................................................................................................. 5 異戊二烯法 .............................................................................................. 5 丙酮法 ..................................................................................................... 5 生產(chǎn)工藝流程 ..................................................................................................... 5 .................................................................................................. 6 第 3章 物料衡算與能量衡算 ............................................................................................ 8 物料衡算 ............................................................................................................ 8 物料衡算的依據(jù) ....................................................................................... 8 Prins 縮合反應的物料衡算 ................................................................... 9 .............................................................................. 10 Prins 異構化反應 的物料衡算 ...............................................................11 能量衡算 ........................................................................................................ 12 1Q 的計算 .............................................................................................. 13 3Q 的計算 ............................................................................................ 14 4Q 的計算 ............................................................................................. 15 5Q 、 6Q 的計算 .................................................................................... 15 2Q 的計算 ............................................................................................. 16 第 4章 工藝設備的工藝設計與選型 ............................................................................... 17 設備工藝設計與選型 ........................................................................................ 17 設備工藝設計與選型的原則 ................................................................... 17 設備工藝設計的主要工作內(nèi)容 ................................................................ 17 反應釜的設計 ................................................................................................... 17 確定筒體和封頭 ..................................................................................... 18 ................................................................ 18 釜體和夾套的強度計算 .......................................................................... 19 支座的選取計算 ..................................................................................... 20 人孔的選擇和補強圈 .............................................................................. 21 接管和法蘭的選擇 ................................................................................. 21 ............................................................................................ 22 冷凝器 ............................................................................................................. 23 ....................................................................................................... 24 第 5章 生產(chǎn)車間設計 .................................................................................................... 25 廠址的選擇 ..................................
