Hey! I would like to know if you please could help me with meaning of equivalence ratio because I don't know how to add ER on Aspen. If you have any email that I can contact I would appreciate it!
Hey, the equivalence ratio of a system is defined as the ratio of the hydrocarbon-to-oxidizer ratio to the stoichiometric hydrocarbon-to-oxidizer ratio: (n(fuel)/n(ox))/(n(fuel)/n(ox))st. n represents the number of moles (mass can also be used), st stands for stoichiometric conditions. Example: we have a mixture of 1 mole of ethane (C2H6) and 1 mole of oxygen (O2). The fuel-to-oxidizer ratio is 1/1=1. The stoichiometric reaction of ethane and oxygen C2H6+3.5O2 --> 2CO2+3H2O. This gives the hydrocarbon-to-oxidizer 1/3.5. Finally, the equivalence ratio of the mixture is 1/(1/3.5)=3.5 I think you can't enter the equivalence ratio directly in Aspen Plus. As far as I know, this is only possible indirectly. I hope I could help. processdesigntools2021@gmail.com
