The Short Cut Column performs Fenske-Underwood short cut calculations for simple refluxed towers. The
Fenske minimum number of trays and the Underwood minimum reflux are calculated. A specified reflux ratio
can then be used to calculate the vapor and liquid traffic rates in the enriching and stripping sections, the
condenser duty and reboiler duty, the number of ideal trays, and the optimal feed location. The Short Cut
Column is only an estimate of the Column performance and is restricted to simple refluxed Columns. For more
realistic results the rigorous Column operation should be used. This operation can provide initial estimates for
most simple Columns
