Problem Statement: Why there is continuous increase of Keq value when product concentration is reduced?
With increase in carbon number, Keq. is also increasing, from the stream results it is evident that concentration is decreasing with increase in carbon number: | Solution: When comparing equilibrium constants, note that the exponents are different for each reaction.
The equation used to calculate Keq in Aspen Plus as follows:
Keq = product (fugacity_i^nu_i) / reactant (fugacity_i^nu_i)
where fugacity_i = fugacity of component i (in atm)
nu_i = stoichiometric coefficient of co... |

Problem Statement: When users upgrade to a new Aspen Custom Modeler (ACM) version but try using the old Microsoft Excel VBA program, to launch ACM, with the following command:
Set ACMObject = CreateObject(ACM Application XX00)
This command may not work with the new version as it did with old version. | Solution: This number: ‘XX00' is related to the version number linked to the different ACM version flavors. For example, for V8.6 this number should be ‘3200’, for V8.8 ‘3400’, and so forth. Therefore, replacing the number in the Excel VBA command for the right version number will solve the issue.
