Pressure distillation column startup and tuning

Start the model Continuous pressure distillation column with default parameters (benzene-toluene mixture, benzene mass fraction 35%, non condensable 2%, 10 trays+boiler, feed tray n°5)

Operating conditions are: feed 2000 kg.h-1, reflux ratio 4, pressure 1.4 to 1.6 bar a, steam to reboiler ~600 kg.h-1, distillate specification 95% of benzene, residue specification 5% of benzene
