Abstract
The design of a prototype chemical process absorption column was carried out to facilitate the sequestration of CO2 from flue gas emanating from an exhaust point of a power generating set. Factors such as ambient temperature and atmospheric pressure where factored into consideration before the fabrication of the absorption column. The rate of the absorbing liquid is 0.1056kg/min and contains 5% mole/mole carbon (iv) oxide. Also the energy and material balance of the entire sequestration process was verified as well as the equipment design for the process was carried out.
