Abstract

This work presents a step-by step calculation strategy to solve the equilibrium model applied to an absorption column. The algorithm used manipulates the equations of the column by grouping them into sets for each stage. Each group is treated separately through a flash calculation. This is a generalization of the algorithm for extraction cascades, which now covers two more cases: a) recirculation between stages and, b) the possibility of several feeding modes. Three case studies with specific settings are presented: a) A columna with a partial reboiler and specified heat flow; b) a column with several feeding modes; and c) a column with recirculation between stages
