By paring with the present SBR polymerization production method, we make a decision to treat emulsion polymerization at low temperature as polymerization production method at last. In the design process, in accordance with the requirements of the mission design, a more detailed material balance and energy balance, equipment for the calculation and selection process, at the same time on styrene butadiene rubber production in the process of attention to safety issues and the three wastes management should be made a note. Drawing the main equipment according to the process design and calculation results。在設(shè)計(jì)過程中，根據(jù)設(shè)計(jì)任務(wù)書的要求，進(jìn)行了較為詳細(xì)的物料 恒 算和能量 恒 算，對(duì)設(shè)備進(jìn)行了工藝計(jì)算和選型，同時(shí)對(duì)聚丁苯橡膠生產(chǎn)過程中的安全注意事項(xiàng)及 ―三廢 ‖治理作了相關(guān)說明。吉林化工學(xué)院 年 月 日 材 料 科學(xué)與 工程學(xué)院 課程 設(shè)計(jì) 年產(chǎn) 5萬噸丁苯橡膠裝置聚合工段工藝設(shè)計(jì) An annual output of 50000 tons of styrene butadiene rubber device polymerization section process design 學(xué)生學(xué)號(hào) 學(xué)生姓名 專業(yè)班級(jí) 指導(dǎo)教師 張 鈺 教 授 聯(lián)合指導(dǎo)教師 張 鈺 教 授 完成日期 吉林化工學(xué)院 Jilin Institute of Chemical Technology 吉林化工學(xué)院 摘 要 本設(shè)計(jì)是以丁二烯和苯乙烯為原料，年產(chǎn) 5 萬噸丁苯橡膠的工藝設(shè)計(jì)。通過比較目前丁苯橡膠的聚合生產(chǎn)方法，最后確定以低溫乳液聚合法作為聚合的工藝生產(chǎn)方法。綜合上述工藝計(jì)算和設(shè)計(jì)結(jié)果，繪制出了主要設(shè)備圖。 Key words: SBR , Emulsion polymerization, Process design, butadiene, styrene monomer 吉林化工學(xué)院 目錄 摘 要 ....................................................................................................................
