Abstract

In the present study a 23 factorial design extended to central composite has been used to analyse the effects of a number of variables including the [CO3=/HCO3-] ratio, initial gas pressure and gas-liquid system temperature on the absorption of CO2 into a sodium carbonate/bicarbonate alkaline solution using a simulated biogas as the gas mixture sample. A response surface analysis using a second order model has shown that the concentration ratio has a significant influence on the carbon dioxide removal process. The model has been statistically validated (analysis of variance) and explained 98.41% of the variability of the CO2 concentration (v/v) change in the simulated biogas. The maximum amount of CO2 removed has been 62.86% during a contact time of sixty minutes.
