Abstract

Carbon (ii) oxide sequestration was carried out from a known emission source with the aid of a prototype laboratory absorber column. The power generating set was duly connected to the column for flow of the flue gas in to it and in contact with the absorbent in a counter current manner. Optimization, modelling and effect of process parameters were carried out with the aid of a Design Expert Software, with concentration of solvent, process/contact duration and volume of solvent as the variables considered for the capture process. The effect of process variables were analyzed using the response surface methodology for carbon (ii) oxide captured and removal efficiencies. Optimum yield for captured carbon (ii) oxide were obtained for concentration of solvent at 6 mol/dm3, contact time of 60 seconds, volume of solvent at 120 millilitre while optimum yield for removal efficiency was obtained at 80.37% for CO and also a quadratic model was developed as the best model for the capture process.
