Dastur Energy has completed the techno-economic feasibility of the Indian Oil Corporation Limited’s (IOCL) carbon capture and utilisation project at the 13.7 million tonnes/year Koyali refinery in Gujarat, India.
The project was funded by a US Trade and Development Agency (USTDA) grant. The project, as designed, provides IOCL with a technically and economically viable solution for capturing up to almost 0.7 million tonnes/year of CO2 from its Steam Methane Reforming (SMR) based Hydrogen Generation Units (HGU) at a very competitive cost structure.
The captured CO2 will be primarily used at the Oil and Natural Gas Commission’s (ONGC) Gandhar oilfields for enhanced oil recovery (EOR) from its maturing oil wells. A part of the captured CO2 is also expected to be liquefied and purified to 99.9% for supply to food and beverage sector consumers.
The carbon capture solution designed by Dastur would allow IOCL to substantially decarbonise its HGU operations and support IOCL’s strategy of producing clean hydrogen. The project also supports the Government of India’s mandate of decarbonising the oil & gas sector. This carbon capture project can be expected to provide a competitive advantage to IOCL in the form of carbon credits in the international markets.
Shri S.S.V. Ramakumar, Director at IOCL, said, “Dastur and its partners evaluated different CO2 sources and carbon capture technologies from multiple vendors to engineer a techno-economically feasible solution that we can implement within the constraints and challenges of a large and complex operating refinery.”
Atanu Mukherjee, CEO of Dastur, commented, “Carbon capture and its effective utilisation is a central building block for enabling the future transition to net zero.”
