摘要
选择大型化工流程模拟软件Aspen Plus对硫碘循环制氢系统进行流程优化设计与模拟,计算系统的质量平衡、能量平衡,并对系统热效率进行评估。碘化氢相中HI浓度采用本生反应实验中的过恒沸浓度,避免高能耗电渗析的使用,从而大大提高系统效率。在不考虑废热发电情况下,与文献值56.8%相比,系统产氢热效率高达68.46%。
A flowsheet of sulfuriodine （SI） thermochemical cycle for the hydrogen production was designed and simu lated by Aspen Plus. The heat and mass balance as well as thermal efficiency of SI process were calculated at fixed H2 production rate of 0. 348mol/s. To avoid the high energy consumption of EED, our experimental data in Bunsen reac tion was used as the HI concentration in HIx phase. Comparing with literature data 56.8% , thermal efficiency for hy drogen production is 68.46% without wasteheat power generation.
