Techno-economic case study: Bio-fixation of industrial emissions at an Indian oil and gas plant

摘要: Abstract In recent years, microalgae have been targeted for emitted carbon capture besides producing value-added products like biofuels, biogas, food supplements and other nutrients. The present work has evaluated the dioxide potential of Chlorella sp utilizing oil gas industrial vent at an Indian processing complex. CO2 is bio-fixation algal biomass was converted into biogas with anaerobic digestion process, which substitutes natural being utilized in heater treater application process chain. pilot scale sequestration using two different cultivation methods compared, suggested as one emerging promising solutions to mitigate climate change supporting energy security challenges. An integrated hybrid model biomass-solar-natural developed analyzed its techno-economic feasibility mitigation approach solar electricity based heat requirements. average productivity found be 186.43 kg ha1d1 quantum 151.23 kg ha1d1. study suggests that matches equivalent requirement crude heating system technically viable. economic financial modeling government regulations (EMRETR-2017) on promotion renewable Renewable Purchase Obligations-2010. results derived a reasonable internal rate return 24% payback time 5.1 credits 191 M$ 125 $ certificate could further reduce makes better environmental sustainable.
