ASPEN simulation for the ammoxidation of propylene to acrylonitrile – seeking expert advice
Thread Content
I saw on the internet that some people said it is necessary to enter the binary interaction parameters manually, but after I entered those parameters provided by Excellence Chemicals, acetonitrile ended up in the liquid phase during the gas-liquid separation process. This is clearly incorrect. If I proceed with the simulation without making any changes, the required number of theoretical plates and reflux ratio become very high, and the separation between acetonitrile and acrylonitrile is poor; the recovery rate of acrylonitrile is also unsatisfactory. Therefore, I ask for the help of all experts out there. Thank you
If the results obtained from directly entering parameters are unreasonable, regression of interaction parameters using experimental data is employed.
