Operating Mode

Batch/Semi-Continuous

Host Equipment

Batch Distillation Vessel

Emissions Port (Vent)

No

Special Input/Output Ports

Yes

 

 

This unit procedure simulates a short-cut batch distillation process. The relative volatility of each component is either specified by the user or calculated by the program (assuming ideal solutions). For each distillation period (cut), the user specifies the reflux ratio and the percent of initial charge distilled during that period. If the distillation time is to be calculated (under rating mode), the user also specifies the vapor rate for each period.

Special Inputs / Outputs

      Bottoms: the designated output port for the bottoms.
