Prediction of Energy Microalgae Production under Flue Gas Using Response Surface Methodology

Biofixation of CO2 by microalgae has become an effective carbon dioxide capture and storage (CCS) technology and it has the potential for large-scale application in decreasing CO2 emission from combustion flue gases. In general, the production of the microalgae under flue gas CO2 carbon sequestration is closely related with the algae species, culture methods, biological conditions, gas conditions and the CO2 concentration. In this paper, the production parameter (biomass) for microalgae chlorella under flue gas was predicted using response surface methodology. It was found that the model agreed well with the experimental data. Further, the interacted analysis indicated that the carbon source, nitrogen source, cell inoculation density and light intensity had important effect on microalgae production.
