Hello
For my master thesis I´m trying to add a MVR to my Aspen Plus simulation.
I´m using a RadFrac Model for distillation. The head product is mainly water (97 wt.-%).
After trying several options suggested in literature or here, the simulation is still not converging.
Maybe someone can help or has some advices?
Thanks in advance
Stefan
I would suggest to add a pseudo stream for the vapor phase on stage 2.
You can manipulate this stream any way you like without disturbing the column convergence itself.
You should add a pre-heater before the compressor to avoid condensation during compression. To specifiy a driving a driving temperature difference between compressed stream condensation and bottoms temperature, a desig-specification on compression ratio or compressor output pressure is helpful.
