In Some kinetic modeling articles, a reaction network has been proposed , where in some components with similar properties ( but different molecular formula and structure), put in a hypothetical component that is named lumped group. for example:
C : C2H4 ,C4H8 ,C3H6.
M : MeOH , DME.
C + M >>>> C , (reaction rate constant and activation energy is specified)
………………..
How can apply such kinetic and reaction network in aspen plus for simulation the reactor and related plant?
Hello professor Benyahia
my problem exactly is stoichiometery, beacause when I want to enter a reaction such mentioned in aspen plus, I face to a error that express : " component cannot be both a reactant and a product of reaction." !!!
thanks.
Hi
whole reaction network and kinetic parameters that I have, is below attached figures.:
Thank you sukanta from your answer. But kinetic of reaction is a important part in my work and must not be negligible.
Thank you for your help sukanta. My effort is finding another appropriat kinetics too. But most of kinetics of the respective reaction is putten in lumped kinetic category.
If you know the form of kinetic equations together with the value of their parameters (regardless of whether the group of componets are used or not) and you can write mass balance equations for a given reactor, then only what you need is a program to integrate a system of differential equations (eg. batch reactor) or to solve a system of nonlinear equations (eg. CSTR). Aspen is first and foremost a very extensive physico-chemical database. Regards,
