- IIT Guwahati and Public Sector Undertaking NTPC Limited are patenting this indigenous technology
- This Technology consumes about 11 per cent less energy compared with existing commercial methods
- It will benefit Oil, natural gas, biogas industries, petroleum refineries and save foreign exchange
- It has the potential to combat climate change and achieve UNs Sustainable Development Goals
Indian Institute of Technology Guwahati has partnered with NTPC Limited to design and develop a highly energy-efficient plant for CO2 capture from power plants
This technology, which works on flue gas using a newly activated amine solvent (IITGS), consumes up to 11 percent less energy compared to commercial activated MDEA (Monoethanolamine) solvent and up to 31 percent less energy compared to benchmark MEA (Monoethanolamine) solvent.
This indigenous technology was developed by a research team led by Prof. Bishnupada Mandal, Department of Chemical Engineering, IIT Guwahati. It has the potential to save a lot of foreign exchange for the nation.
The outcomes of this project will benefit oil, natural gas, biogas industries, and petroleum refineries. This project, through its research and education, will support and strengthen the UNs Sustainable Development Goals (SDGs) as well.
After successful completion of test studies, the pilot plant has been shifted to NTPC’s NETRA facility. IIT Guwahati Team and NTPC Limited are in the process of patenting the technology. This development has the potential impact to combat global climate change. The next phase of the study will involve the testing of pilot-pant using industrial flue gas.
Elaborating on the practical applications and benefits of Technology, Prof. 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 MEA and other proprietary solvent-based technologies are available for CO2 capture in the chemical industry. This technology is utilized in coal and gas-fired power plants mainly to produce food-grade CO2 in small quantities (compared to CO2 capture in power plants). However, the process is energy-intensive, if adopted for large-scale CO2 capture in power plants. IIT Guwahati has developed an energy-efficient amine-based process for CO2 capture from flue gas.
The growth in the electricity sector is a prerequisite to achieving India’s ambitious policy goal of ‘Electricity for All’ and maintaining significant growth in its Gross Domestic Product (GDP). At the same time, India supports global efforts toward the research and development of technologies aimed at reducing CO2 emissions. This technology will help achieve both of these goals simultaneously.
