1、河南城建學(xué)院專(zhuān)科畢業(yè)設(shè)計(jì)設(shè)計(jì)說(shuō)明畢業(yè)設(shè)計(jì)[論文]題目：3萬(wàn)噸每年粗苯精制工藝設(shè)計(jì)學(xué)院：化學(xué)與材料工程學(xué)院專(zhuān)業(yè)：煤炭深加工與利用姓名：學(xué)號(hào)：指導(dǎo)老師：完成時(shí)間：2013年5月27日iii河南城建學(xué)院專(zhuān)科畢業(yè)設(shè)計(jì)設(shè)計(jì)說(shuō)明設(shè)計(jì)說(shuō)明粗苯精制工藝，是將粗苯經(jīng)化學(xué)加工轉(zhuǎn)換為氣體，液體和固體產(chǎn)物，并將氣體和液體產(chǎn)物進(jìn)一步加工成一系列化學(xué)產(chǎn)品的過(guò)程。目前粗苯精制工藝過(guò)程有：酸洗精制法和加氫精制法。酸洗精制法工藝簡(jiǎn)單，該法在我國(guó)焦化廠得到廣泛應(yīng)用。加氫精制法工藝復(fù)雜，對(duì)設(shè)備材質(zhì)和自動(dòng)控制要求高，該法在我國(guó)也得到一定的應(yīng)用。本設(shè)計(jì)采用酸洗精制對(duì)
2、粗苯精制工藝進(jìn)行了設(shè)計(jì)計(jì)算，著重設(shè)計(jì)計(jì)算了粗苯精制過(guò)程的關(guān)鍵設(shè)備。主要包括物料衡算，主要塔設(shè)備的工藝尺寸計(jì)算，并對(duì)關(guān)鍵設(shè)備進(jìn)行了機(jī)械強(qiáng)度校核。通過(guò)物料衡算得到苯每小時(shí)產(chǎn)量為4.17t/h；按清晰分割計(jì)算得：輕苯進(jìn)料量為5.796t/h；酸洗反應(yīng)器進(jìn)料量為5.723t/h；吹苯塔進(jìn)料量為5.715t/h；按非清晰分割計(jì)算得：純苯塔進(jìn)料量為5.4863t/h甲苯塔進(jìn)料量為1.3125t/h；二甲苯塔進(jìn)料量為0.5302t/h。通過(guò)對(duì)關(guān)鍵設(shè)備工藝尺寸計(jì)算得到：吹苯塔塔高H=27.45m；純苯塔塔高為17.966m，塔徑為1.1m。
3、通過(guò)對(duì)關(guān)鍵設(shè)備機(jī)械強(qiáng)度校核得到：純苯塔質(zhì)量載荷為7942.18Kg；風(fēng)載荷：1-1截面為84503.059N·m。關(guān)鍵字：粗苯、精制、苯通過(guò)設(shè)計(jì)計(jì)算，得到以下主設(shè)備圖紙iii河南城建學(xué)院專(zhuān)科畢業(yè)設(shè)計(jì)設(shè)計(jì)說(shuō)明DesignspecificationCrudebenzolrefiningprocess,isthechemicalprocessingofcrudebenzolisconvertedintoagas,liquidandsolidproducts,andthegasandliquidproductisfurtherpro
