Dear all,

Hope you can help to sort out this problem. I am not experience in petroleum simulation. First time dealing with it. The reaction product from Fischer Tropsch (FT) synthesis is made up of paraffin and olefin. See the equation below:

nCO + (2n+1) H2 --> CnH(2n+2) + nH2O

In simulation, how should we deal with this? As in, what do we input in Aspen Plus if we want to produce this large range of "n" value product? I totally have no idea. Heard something about pseudocomponent, but I'm not sure how to do it.

Appreciate your precious advice.

Thanks.

Dear,
Refer the basic document regarding how to create Pseudo components.

I am simulating the same reaction.

Can you please guide me how to define this reaction in Aspen Plus?

I have defined product as Pseudocomponent and also defined the kinetics. But Aspen shows error in mass balance of reaction that is because I am not able define 'n' in reaction.

Can you please guide me how to define this reaction?

Thanks
