Please I need help

hi,

Let you consult aspentech , link above

The unit operations that come with the standard programs do not supply the fidelity that satisfies serious hydrocracker modelers. You can add your hydrocracker custom unit operation model to AspenPlus or Aspen Hysys. If you don't want to develop your own custom unit, you can purchase or license a unit. AspenTech has refinery reactor models they vend. See https://www.aspentec...finery-reactors

Use the Hysys hydrocracker model.  There are now two models the older kinetic model with around a hundred components and a couple of hundred reactions modelled.  There is also know a molecular model which models literally thousands of reactions.  Neither model is trivial to use.

A simpler approach would be to use a much simpler but less rigorous model like the one in Petrosim.
