Abstract
The objective of the present study was to set up a
small-scale pilot reactor at ONGC Hazira, Surat, for
capturing CO2 from vent gas. The studies were carried out
for CO2 capture by either using microalgae Chlorella sp.
or a consortium of microalgae (Scenedesmus quadricauda,
Chlorella vulgaris and Chlorococcum humicola). The
biomass harvested was used for anaerobic digestion to
produce biogas. The carbonation column was able to
decrease the average 34 vol.% of CO2 in vent gas to 15
vol.% of CO2 in the outlet gas of the carbonation column.
The yield of Chlorella sp. was found to be 18 g/m2/day.
The methane yield was 386 l CH4/kg VSfed of Chlorella sp.
whereas 228 l CH4/kg VSfed of the consortium of algae.
