摘要

利用Aspen Plus软件对N_2O_4提纯工艺进行模拟计算,选择NRTL热力学模型,对精馏塔的各个参数进行灵敏度分析,得到精馏塔的最佳操作参数。采用Aspen Dynamics为精馏工艺设计控制方案,并进行实验验证,最终产品中N_2O_4的质量分数稳定在99.987%左右,相当水含量稳定在110×10~(-6)左右,产品质量稳定可靠。
        The N_2O_4 purification process was simulated by ASPEN PLUS software.The NRTL thermodynamic model was selected to analyze the sensitivity of the distillation column parameters,and the optimum operating parameters of the distillation column were obtained.Aspen Dynamics was used to design the control scheme for distillation process.The experimental results showed that the mass fraction of N_2O_4 in the final product was stable at 99.987%,the equivalent water content was stable at 110×10~(-6),and the product quality was stable and reliable.
