Welcome in this new tutorials for Aspen Plus. We will focus on thermodynamic chemical equilibrium analysis using the RGibbs reactor.
This type of reactor uses the method of direct minimization of Gibbs free energy.
It is useful when reactions occurring are not known or are high in number due to many components participating in the reactions.
This is the only Aspen Plus block that will deal with solid-liquid-gas phase equilibrium.
We will apply Rgibbs block to the methane steam reforming reaction.
This reaction is endothermic and it is useful to produce the syngas. To fully describe the system we need to add a second reaction best know as water gas shift, which is exothermic.
Using these 2 reactions, the species that we will have at the equilibrium are: methane, steam, hydrogen, carbon monoxide, carbon dioxide.
The equilibrium will be investigated at ambient pressure and in the temperature range between 300 and 600°C with a steam to carbon ratio of 3.5
