Good day maam/sir,

I'm a chemical engineering student that is currently doing a plant design project. Our chosen topic was a cyclohexane production plant specificaly from the hydrogenation of benzene. We already have a working simulation at the present but our instructor commented that some of the material streams ( mainly from the purge and product stream) are two phased which ideally should be single phased. I'm wondering how we can resolve this issue and if it has something to do with considering the pressure drops at certain stages of the simulation?

Thank you very much
