Study of interface composition and height column during absorption process

Packed and tray columns are widely used in the study of gas-liquid interaction during mass and heat transfer process. There exist a variety of column configurations and each design is performed according to specific purposes, such as nature of processing feed, number of components, product streams, type of operation, etc. Continuous contact between phases allows mass transfer, which is the case of process like absorption, distillation and extraction were fluid phases can be added at constant rate to the column. Understanding of mass transfer during such process is important for design purposes because proper design will allow correct separation and extraction of components. The concentration of components being transferred changes as it flows through the column. As a result, the concentration driving force changes along the height of the column. In the present paper we aim to model a gas absorption process after performing a mass balance along the column and determining the interface composition (mole fraction) and height of a packed tower.
