New Delhi: IIT Guwahati has recently collaborated with National Thermal Power Corporation (NTPC) Limited to design and build a high-efficiency carbon dioxide capture facility for power plants.
IIT Guwahati claims that this technology will aid natural gas and petroleum refineries, among other industries, in combating global climate change. A research team led by Bishnupada Mandal, IIT Guwahati Department of Chemical Engineering, created the indigenous technique.
According to a press release from IIT Guwahati, this technology, which uses a newly activated amine solvent (IITGS) to work on flue gas, uses up to 11% less energy than commercial activated MDEA (Monoethanolamine) solvent and up to 31% less energy than benchmark MEA (Monoethanolamine) solvent.
Bishnupada Mandal, Department of Chemical Engineering, IIT Guwahati, said, “The increase in anthropogenic CO2 emissions is one of the reasons attributed to global warming. Extensive research efforts are being made by the scientific community to overcome this global challenge that includes modifications to existing technologies through efficiency improvement for CO2 capture.”
The pilot plant has been relocated to NTPC's NETRA site following the successful completion of test studies. IIT Guwahati Team and NTPC Limited are in the process of patenting the technology. This breakthrough has the potential to aid in the fight against global warming. The study's next phase will entail pilot-plant testing using industrial flue gas.

In the chemical sector, the MEA and other proprietary solvent-based methods are available for CO2 capture. This technique is mostly used in coal and gas-fired power stations to create a moderate amount of food-grade CO2 as compared to CO2 capture in power plants.
However, if used for large-scale CO2 collection in power plants, the method is energy-intensive. IIT Guwahati has developed an energy-efficient amine-based CO2 collection technique from flue gas.
Growth in the electrical industry is required to achieve India's ambitious policy objective of "Electricity for All" and to maintain considerable growth in the country's GDP. Simultaneously, India supports worldwide efforts to conduct research and development on technology to reduce CO2 emissions. This technology will aid in achieving both of these objectives at the same time.
