Dear all, I am currently stuck trying to insert a reaction kinetics into HYSYS. I am using a heterogenous catalytic reaction in HYSYS, and my reaction is as follows:

 

r= kK_MeOH(P_MeOH −((P_DMEP_Water)/(P_MeOHK_eq))) / (1+K_MeOHP_MeOH +K_WaterP_Water)

 

where 

k = 3812.11 exp (-69383.66/RT)

 

K_M = 67.42 exp(108108.6/RT)

 

K_w = 2.17 exp( 89828.61/RT)

 

As you can see, I have the kinetic parameters available and HYSYS requires the input of A and E of the forward and backward reaction. Currently, I am thinking that the A and E of the forward reaction would be the product of of k and K_meoh. However for the reverse reactions I believe it would be kK_meoh/K_eq  and I do not have the values for K_eq so I am wondering how should I put this into HYSYS. 

 

As for the terms that took the adsorption of reactants/products onto catalyst, I have inserted them into HYSYS but any help or knowledge regarding that is appreciated as well. 

 

Regards,

Fysys

It sounds like you have langmuir hinshelwood kinetics and you are mistakenly trying to input it as reversible kinetic reactions.
