Abstract
Due to the ever-increasing cost of energy and more stringent pollution standards for atmospheric emissions, it is desirable to
improve absorption processes for the removal of carbon dioxide from flue gas. The research needs have been reviewed for CO2
capture from flue gas by aqueous absorption/stripping. A close-looped absorption/stripping pilot plant with 15 cm ID columns was
used to capture CO2 using a new blended amine (AIT 600) solution. Both the absorber and stripper contained 1.5 m of packing. The
pilot plant campaign consisted of 27 runs at 9 operating conditions over the period of study. Various absorber temperature, gas and
liquid rates and lean CO2 loadings were tested. In this work by using Taguchi statistical method we studied the effect of operating
conditions on the CO2 capture efficiency. The operating parameter used in this study consisted of the following: gas flow rate, CO2
mole fraction in feed gas, liquid flow rate and absorber temperature.
