摘要
应用ＰＲ状态方程和改进的混合规则对深冷净化精馏塔进行了模拟计算，得到了温度、压力、汽液相流率和组成沿金塔的分布数据．计算结果表明：改进的混合规则可用于低温含氢体系，其计算结果与文献设计值符合很好．
The PR equation of state and mixed rules modified are used for the simulated calculation of cryogenic purifier distillation. The distributing data of temperature, pressure, vapor rate, liquid rate and compositions along whole distillation are obtained. The results have shown that the modified mixed rules can be used for hydrogen - containing systems at low temperatures. The computation results are in good agreement with the design values of reference.
