【正文】 活飲用水處理和日用化學(xué)品生產(chǎn)的主要原料，與人民生活息息相關(guān)。由于其具有難燃、抗化學(xué)腐蝕、耐磨、電絕緣性優(yōu)良和機械強度較高等優(yōu)點，廣泛應(yīng)用于農(nóng)業(yè)、石油化工、輕工、紡織、化學(xué)建材、電力、冶金、國防軍工、建材、食品加工等國民經(jīng)濟各命脈部門， 在國民經(jīng)濟發(fā)展中具有舉足輕重的地位。 Heat balance。 Thick vinyl chloride rectification。 本文設(shè)計的電石乙炔法生產(chǎn)粗氯乙烯在工藝上可滿足要求。此法是以電石為原料，電石水解生產(chǎn)乙炔，氯堿生產(chǎn)中產(chǎn)生的氯氣和氫氣直接合成法合成氯化氫，由乙炔和氯化氫經(jīng)凈化后在轉(zhuǎn)化器中合成粗氯乙烯單體，粗氯乙烯單體經(jīng)精餾后得到精氯乙烯 單體，精氯乙烯單體經(jīng)懸浮聚合得到PVC。 本次設(shè)計對年產(chǎn) 6 萬噸 PVC 精餾工段進行工藝設(shè)計。 摘要 聚氯乙烯是世界上最早實現(xiàn)工業(yè)化生產(chǎn)的塑料品種之一。由于其具有難燃、抗化學(xué)腐蝕、耐磨、電絕緣性優(yōu)良和機械強度較高等優(yōu)點，廣泛應(yīng)用于農(nóng)業(yè)、石油化工、輕工、紡織、化學(xué)建材、電力、冶金、國防軍工、建材、食品加工等國民經(jīng)濟各命脈部門， 在國民經(jīng)濟發(fā)展中具有舉足輕重的地位。采用電石乙炔法制取氯乙烯。確定了生產(chǎn)方法之后對氯乙烯合成工段、精餾工段進行了物料衡算、熱量衡算和設(shè)備選型計算。 關(guān)鍵詞 ： PVC 合成；粗氯乙烯精餾；物料衡算；熱量衡算；設(shè)備選型 Abstract Polyvinyl chloride (PVC) is one of the earliest industrialization production of plastic varieties in the world. Since it has flame retardant, resistance to chemical corrosion, wear resistance, good electrical insulation, and the advantages of high mechanical strength, widely used in agriculture, petroleum chemical industry, light industry, textile, chemical, building materials, electric power, metallurgy, national defense war industry, building materials, food processing, such as the lifeline of national economy department, has a pivotal position in the national economic development. The design on the annual output of 60000 tons of PVC distillation section for process design. Take vinyl chloride by calcium carbide acetylene method. This method is based on calcium carbide as raw materials, calcium carbide hydrolysis to produce acetylene, chlorine and hydrogen generated in chloralkali production were direct synthesis method of hydrogen chloride synthesis by acetylene and hydrogen chloride synthesis in the converter after purification thick vinyl chloride monomer, coarse after rectification for vinyl chloride monomer vinyl chloride monomer, pure PVC by suspension polymerization of vinyl chloride monomer. Determine the method of production of vinyl
