摘要
针对电石法合成氯乙烯的列管式反应器,基于传热系数的不同,建立了氯乙烯合成过程的一维均相数学模型,根据乙烘流量、氢气浓度、反应压力、列管直径用该模型计算了二组转化器列管内的轴向温度分布和乙烘含量分布,给出了转化反应的优化操作方法。
Based on the different heat transfer coefficients, a one-dimensional homogeneous mathematical model was established for the synthesis of vinyl chloride from calcium carbide in a tubular reactor. The axial temperature distribution and acetylene content distribution in the tubular tubes of the secondstage converters were calculated by the model according to the flow rate of acetylene, hydrogen concentration ,reaction pressure and tubular diameter. The optimal operation method for the conversion reaction was given.
