Hi ;

 

While installing a Butanizer After the ethanizer in HYSYS  i didn't find the adequate spec to release most of butane without loosing propane in overhead product.

 

I tried propane fraction of 0.05 in condenser and 5e-3 butane in reboiler but the column don't want to converge.

 

The feed stream is composed of :

 

i-Butane         0,1357
n-Butane         0,2534
i-Pentane         0,122
n-Pentane         0,1094
n-hexane       8,073e-002
Propane          0,297

 

feed stream conditions :

 

Vapour / Phase Fraction              0,61989
Temperature [C]                             67,02
Pressure [bar_g]                          5,93675
Molar Flow [kgmole/h]                 18,70955

 

Column conditions :

 

operating Pressure                   689 kPa

Number of trays                             25

 

 

Thanks
