Modelling Carbon Monoxide Capture through PostCombustion Using Saw Dust Ash Leachate

It has become expedient to solve the prominent issues of carbon monoxide hazards by promptly capturing it at the source. This paper presents the analysis of carbon monoxide capture experimental results obtained with the use of saw dust ash leachate as the sorbents for the post-combustion capture of carbon monoxide from exhaust of Yamaha EF1000. The Yamaha EF1000 was appropriately connected to a laboratory scale glass absorber column for the counter current flow of the flue gas with the sorbent. Modelling and optimization of the process were carried out using Design Expert software version 10, with concentration of sorbents, process time and sorbent flow rate as the process variables. Quadratic model was obtained as the best model for the capture process, with the carbon monoxide composition of the exit flue gas as response. For the ash leachate, response value of 3.557% as optimum, at sorbent concentration of 21.795g/L, process time of 9.997mins and sorbent flow rate of 200.278cm3 /min, respectively were achieved. From the results obtained, saw dust ash leachate effectively captured CO.
