Dear All,
I have already started methylamine production plant (from ammonia and methanol) simulation via aspen-hysys.
the simulation has been converged via " PSRK" EOS and aspen properties.
However, some physical properties (especially density) has major differences with the in-hand documents.
For example, even water density shows major difference (740 Kg/m3 for Water at 40 C).
How could i resolve this issue?
all binary coefficients have been defined zero by Hysys (Aspen Properties).
