- W3208447766 abstract "Methanol steam reforming (MSR) in packed-bed reactors (PBRs) with membrane filters has emerged as promising hydrogen (H 2 ) production system to overcome limitations of conventional membrane reactor (MR), which has H 2 permeable membrane inside. In this study, techno-economic analysis is conducted based on results of process simulation using Aspen HYSYS® to assess technical and economic feasibility of MSR in systems of different number of PBRs and membrane filters and key economic parameters are presented. Also, effects of techno-economic parameters of reaction temperature, H 2 permeance, and the number of PBRs and membrane filters on a unit H 2 production cost are investigated, individually and comprehensively, in the ranges from 448 to 513 K, from 5 × 10 − 6 to 5 × 10 − 5 mol m −2 s −1 Pa −1 , and one to four PBRs with zero to three membrane filters. Based on techno-economic analysis results, regression function for the unit H 2 production cost is achieved and optimization of operating conditions using GAMS© is conducted showing the minimum unit H 2 production cost of 7.03 $ kgH 2 −1 and optimized conditions of 513 K, 5 × 10 − 5 mol m −2 s −1 Pa −1 , and two PBRs with one membrane filter. In addition, to investigate environmental feasibility, carbon footprint analysis is performed with comparing CO 2 emissions according to techno-economic parameters. • Process simulation model for multi-stage packed-bed reactors and membrane filters constructed. • Economic analysis and carbon footprint analysis with various conditions of techno-economic parameters conducted. • Optimum conditions of 513 K, 5 × 10 − 5 mol m −2 s −1 Pa −1 , and two PBRs with one membrane filter confirmed. • Minimum unit H 2 production cost and CO 2 emission rate of 7.03 $ kgH 2 −1 and 0.083 kmolCO 2 kmolH 2 −1 obtained. Techno-economic and carbon footprint analysis based on process simulation was conducted to figure out unit H 2 production costs and CO 2 emission rates under various operating conditions. Optimized operating conditions for minimum H 2 production cost were also investigated." @default.
