where:

$image\COLPOP08.gif$ = vapor mole fraction for component i on tray n

$image\COLPOP13.gif$ = equilibrium vapor mole fraction for component i on tray n based on tray liquid composition

Vaporization Model

where :

$image\COLPOP10.gif$ = Effective equilibrium K-value for component i on tray n

$image\COLPOP14.gif$ = Equilibrium Kvalue for component i on tray n based on tray n liquid composition

Equilibrium Model
