title: Pilot project at Hazira, India, for capture of carbon dioxide and its biofixation using microalgae.
abstract: The objective of the present study was to set up a small-scale pilot reactor at ONGC Hazira, Surat, for capturing CO2from vent gas. The studies were carried out for CO2capture 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 CO2in vent gas to 15 vol.% of CO2in 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 VSfedof Chlorella sp. whereas 228 l CH4/kg VSfedof the consortium of algae.
