Batch Distillation Procedure

Overview

A Batch Distillation Procedure can be created by selecting the following menu option:
Unit Procedures } Distillation } Batch

	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.
