In the present time, hydrogen is generally produced from natural gas using the conventional reactors that have some disadvantages such as thermodynamic equilibrium equation, high temperature, and carbon deposition. To overcome these disadvantages, the interest in the membrane reactors that provides both hydrogen production and hydrogen separation in the same unit is increasing, therefore the produced hydrogen is permeated from the reaction side to the permeation side continuously, and thus this decreases the thermodynamic equilibrium limitation. In this study, a mathematical model of a membrane reactor was coupled with the models of the balance of plant components (compressor, boiler, burner, pump, blower, and two mixers), and a system-level energy analysis was conducted. Molar flow rates, temperatures, and pressures for all states in the system were found. In addition, the effects of reaction temperature on H2 production, CO2 production, H2 yield, and system efficiency were investigated. When the membrane reactor operating temperature increases from 673 K to 773K, the H2 production, collected CO2, H2 yield, and system efficiency are increased by 9.88%, 1.48%, 9.94%, and 9.86%, respectively.
