ttheEthylene and chlorine in a posite catalyst ferric chloride and lithium chloride under the existing conditions of the reactions that produce 1, 2dichloroethane (EDC), this reaction is exothermic reaction, reaction heat generation through the gasification dichloroethane removed, product contains a small amount of light ponent chloroethane, etc., through the take off light tower to remove one of the light ponents, system purity higher EDC. This paper design and list some of the production process of anomaly and processing mode. Vinyl chloride preparation 2dichloroethane oxygen the world most advanced production 2dichloroethane method. Raw materials via ethylene, oxygen, hydrogen, oxygen flow regulating after entering within reactor in chloride, fluidizedbed catalyst in the presence of 230 ~ 255, ℃, ~ Mpa conditions, happen oxygen chlorination generating 1, 2dichloroethane, which release a lot of heat. The response gas quenching, condensing, CO2 steam extraction, decantation separation and sodawash removal trimethoxysilane acetaldehyde and chlorine after treatment, such as ethanol made from pure product 1, 2dichloroethane (EDC). 2dichloroethane is the production of vinyl chloride monomer, and then produce PVC, this technology research greatly reduces the past conventional production 2dichloroethane risk, achieves truly peopleoriented, technology innovation. Keywords: ethylene dichloride, production principle, process flow, exception handling,oxygen chlorination and hydrogen chloride, ethylene and oxygen4摘要 5Abstract 6第一章 緒論 2 2 3 4第二章 EDC生產(chǎn)原理及工藝流程 6 6 7第三章 正常生產(chǎn)主要控制檢查點(diǎn) 8 8 8 DC反應(yīng)器及一級(jí)冷凝 9 11 11第四章操作過程中若干的異常現(xiàn)象、原因及處理方法 12結(jié)論 14產(chǎn)品分析數(shù)據(jù) 14總結(jié): 14參考文獻(xiàn) 15致謝 16第一章 緒論近年來,隨著時(shí)間聚氯乙烯生產(chǎn)的快速發(fā)展,世界二氯乙烷的生產(chǎn)發(fā)展很快。該反應(yīng)為放熱反應(yīng),反應(yīng)熱通過EDC汽化移走。乙烯直接氯化制備二氯乙烷是目前世界上最先進(jìn)的生產(chǎn)二氯乙烷的方法之一。四.畢業(yè)設(shè)計(jì)(論文)結(jié)束應(yīng)提交的材料:論文電子稿論文打印搞過程資料記錄本(實(shí)驗(yàn)記錄本) 指導(dǎo)教師: 教研室主任 年 月 日 年 月 日摘要乙烯與氯氣在復(fù)合催化劑氯化鐵和氯化鋰存在的條件下反應(yīng)生成1,2二氯乙烷(EDC),該反應(yīng)為放熱反應(yīng),反應(yīng)產(chǎn)生的熱量通過氣化二氯乙烷移走,生成物中含有少量的輕組分氯乙烷等,通過脫輕塔去除其中的輕組分,制得純度比較高的EDC。4. 第四周:撰寫畢業(yè)論文。2. 第二周:選擇出設(shè)計(jì)方案。乙烯平衡氧氯化法由乙烯、氯氣和氧氣生產(chǎn)氯乙烯,整個(gè)工藝過程既不產(chǎn)生氯化氫,又不消耗氯化氫,大大降低了原料的成本,此法是目前世界上公認(rèn)的技術(shù)經(jīng)濟(jì)較合理的方法,全世界93%以上的氯乙烯是采用乙烯平衡氧氯化法生產(chǎn)的。畢業(yè)設(shè)計(jì)(論文)年產(chǎn)30萬噸氯乙烯(VCM)工藝設(shè)計(jì)With An Annual Output of 300000 Tons of Vinyl chloride (VCM)Process Design 一.選題意義及背景氯乙烯單體(VCM)是生產(chǎn)聚氯乙烯樹脂的主要原料,其產(chǎn)品的質(zhì)量和成本直接影響到聚氯乙烯樹脂的質(zhì)量和成本。氯乙烯生產(chǎn)工藝經(jīng)歷了較長(zhǎng)時(shí)間的生產(chǎn)和工藝改造,產(chǎn)生了電石法、二氯乙烷法等工藝,發(fā)展到目前世界上最先進(jìn)的的工藝屬乙烯平衡氧氯化工藝。2. 畢業(yè)設(shè)計(jì)(論文)主要內(nèi)容:1. 工藝生產(chǎn)方法確定、生產(chǎn)流程設(shè)計(jì)與論證2. 工藝計(jì)算(包括物料衡算,熱量衡算)3. 酯化合成工藝主要生產(chǎn)設(shè)備設(shè)計(jì)與選型4. 安全生產(chǎn)與環(huán)保治理措施三.計(jì)劃進(jìn)度1. 第一周:在完全理解設(shè)計(jì)任務(wù)書的基礎(chǔ)上查閱資料,做好準(zhǔn)備工作,包括:了解學(xué)位論文的格式、查閱相關(guān)文獻(xiàn)(萬方數(shù)據(jù)、中國(guó)期刊網(wǎng)、維普資詢、碩博論文等)、學(xué)習(xí)氯乙烯的工藝設(shè)計(jì)方法。3. 第三周:參照數(shù)據(jù)。5. 第五周:進(jìn)行畢業(yè)答辯。本論文設(shè)計(jì)同時(shí)列
