Abstract

Methane steam reforming has been simulated, analyzed and optimized with the aid of Aspen Plus, in this work. The model of the steam reforming process used was developed using equilibrium reactor type. Both steam reforming process model with and without mixer were developed and simulated in Aspen Plus environment. The sensitivity analyses and the optimization of the process were accomplished using the Sensitivity and the Optimization sections of Model Analysis Tool of Aspen Plus. The results obtained revealed that the simulations with and without mixer gave the same mole fractions of the process components and that the simulation with liquid methane feed was able to produce highmole fraction of the desired product(hydrogen) at approximately atmospheric pressure. Furthermore, it was revealed from the sensitivity analyses of the process that optimization was necessary to obtain the operating variables that would yield hydrogen in very high and highest purity among the components involved in the process and the optimization was able to give a satisfactory value of 0.7432 as the mole fraction of hydrogen present in the top product of the reactor when the optimum reactor temperature, reactor pressure, volumetric flow rate of feed water and volumetric flow rate of feed methane were approximately 964.89 oC, 1 bar, 0.0172 L/min and 0.0353 L/min, respectively.
