Abstract

The purpose of this work was to improve the efficiency of carbon dioxide (CO2) capture from desulfurized biogas by microalgae, i. e. Chlorella sp., in a photobioreactor which comprised an absorption column and an aeration column. The light intensity was controlled at 3,207lux while the biogas and air flow rates were fixed at 0.045 and 3.600 liters per minute, respectively. The medium recirculation rate between the two columns were a range of 0.25-1.25 liters per minute to study the CO2 capture performance. The results showed that the CO2 removal efficiency depended on the recirculation rate and the maximum efficiency was found to be 78.5%. The higher recirculation rate resulted in the higher CO2 removal rate which could increase the methane content in the biogas to be as high as 25.2%. It was found that 1 kilogram of microalgae could absorb 354 kilogram of CO2 annually.
