摘要
建立了不同吹扫模式下碘化氢(HI)分解膜反应器有限时间热力学模型,将吹扫气流率、反应进口压力、渗透膜厚度、反应器长度作为决策变量,以HI转化率最大、H2回收率最大、总熵产率最小为目标开展多目标优化.通过研究发现,在给定的决策变量变化范围内HI转化率和H2回收率最大两者具有一致性,但两者无法与总熵产率最小同时达到最优;相比顺流吹扫模式,逆流吹扫模式下Pareto前沿目标值均具有较高的HI转化率和H2回收率.使用不同的决策方法选取最优解,顺流模式下的TOPSIS决策点和逆流模式下的LINMAP决策点具有较小的偏差因子可作为反应器参数设计最优解.
Abstract
A finite time thermodynamic(FTT)model of HI decomposition membrane reactor un-der different sweep modes is established.The sweep flow rate,reaction inlet pressure,permeable membrane thickness and reactor length are taken as decision variables,and the multi-objective opti-mization is carried out to maximize HI conversion rate,H2 recovery rate and total entropy generation rate.It is found that the HI conversion rate and H2 recovery rate are consistent to some extent within a given range of decision variables,but they cannot reach the optimum with the total entropy gener-ation rate at the same time.Compared with the co-current sweep mode,the target values of Pareto front have higher HI conversion and H2 recovery in the countercurrent sweep mode.Different deci-sion methods are used to select the optimal solution.TOPSIS decision point in cocurrent mode and LINMAP decision point in counter-current mode had smaller deviation factors and could be used as the optimal solution for reactor parameter design.
