Possible Sharp Splits in Columns with Two Feeds

Possible Sharp Splits in Columns with Two Feeds 

To determine possible splits in columns with two feedings, it is necessary to find 

The similar condition should be valid for the trajectory tear-off regions Rege  

Therefore, to identify the trajectory tear-off segments and regions, it is necessary at the beginning to calculate the values of phase equilibrium coefficients of 

Sharp spht in the column with two feedings is possible, if the conditions for product compositions are valid (1) top product point and entrainer point should belong to the same boundary elements of concentration simplex as the trajectory
