T
he purpose of this study is to assess technology of capturing carbon dioxide (CO
2
) emissions generated by industry that
use combustion systems by utilizing microalgae
Chlorella vulgaris.
The microalgae were cultivated in bioreactor culture
pond raceway type. The experiment is expected to be useful in mitigating the effects of greenhouse gases in reducing the CO
2
emissions. The aim of this study was to sequestrate CO
2
by microalgae
Chlorella vulgaris
under the different level of CO
2
. The
research activities included: 1. characterization of boiler flue gas; 2. operation of culture ponds; and 3. sampling and sample
analysis. The results of this study showed that the initial assessment absorption of the flue gas by microalgae using 1000 L
raceway pond completed by heat exchanger were quite promising. The results indicated that transfer of CO
2
into the pond
culture system was run well. This was identified from the success of cooling the boiler flue gas from the temperature of about
200°C to below ambient temperature. Except for temperature, the gas bubbles into the culture media were quite fine. Therefore
the contact between the gas and the media was well performed. Efficiency of CO
2
absorption by
Chlorella vulgaris
reached 0%,
99.8% and 96.2% with average CO
2
level concentration of 0%, 6.2% and 8.1% respectively. The ultimate CO
2
sequestration rate
of
Chlorella vulgaris
was 0.1462g/L/d recorded at 8.1% CO
2
concentration.
