Carbon dioxide, a major greenhouse gas that need to be removed from flue gas produced by combustion of fossil fuels in order to manage future climate changes. Although conventional wet scrubbing techniques exist for removal of carbon dioxide from gas streams, the wet scrubbing techniques must improve to process large volumes of flue gas at acceptable thermal efficiencies and minimal costs. Amine scrubbing is one such technique to remove $C{O}_2.$ To make the process more efficient, various areas of improvement were investigated: gas$-$liquid contacting area, the type of absorbent etc.

In addition various research has been performed on mono$-$ethanolamine $($MEA$)($traditional solvent$)$ with different packing material and significant improvements in $C{O}_2$ removal were achieved.

In this project it is aimed to compare number and height of mass transfer units for different packing materials and in addition it is aimed to determine number stages in a tray column.

It is desired to compare the packing materials shown in table below:
