Abstract
A crucial part of combating climate change, which is undoubtedly our planet’s grave threat, is carbon capture and storage (CCS). Although CO2 emissions have been a global concern for many years, there has been very little consistent progress. Minimizing the effect of carbon emissions on environment can be reduced by utilizing the captured and stored CO2. Chemical and fuel sectors are increasingly interested in the use of carbon dioxide (CO2) as a feedstock. In petrochemical industry, carbon dioxide is employed for the synthesis of urea and other useful compounds. The captured and stored CO2 can be utilized for methanol synthesis and methane gas production, which boost the carbon utilization efficiency. This study briefs the global overview of the carbon capture and storage (CCS) techniques giving more emphasis on pre- and post-combustion CO2 capture, Oxyfuel combustion, CO2 transport and its utilization in oil & gas industry. In addition, a stoichiometric calculation clearly represents the amount of carbon dioxide emitted (2034.4 gm/day) can be transformed to 691.69 gm of urea and 1109.67 gm of methanol per day, according to a case study of Singareni Thermal Power Plant.
