- Capture of CO2 from flue gas of coal based power plant and its conversion to methanol is a priority area for NTPC.
- The project will strengthen the Government of India vision of ‘Methanol Economy’ in our country.
- ‘Methanol Economy’ would, in turn, reduce India's dependence on oil imports and simultaneously curb the pollution from electricity sector and thereby helping India meet its Paris Climate Change Agreement obligation to cut carbon emission intensity by 33-35% by 2030.
Salient features
The 10 TPD Flue Gas- CO2 to Methanol Plant (FG-CTM) Plant shall comprise of following 3 units.
- Carbon Capture Unit: For capturing 20 TPD CO2 from thermal plant flue gas through energy efficient absorption process.
- Hydrogen Generation Unit: For generating 2 TPD Hydrogen through electrolysis of water, hydrogen being other ingredient for methanol production.
- Methanol Production Unit : For the conversion of CO2 to Methanol through catalytic hydrogenation process
Benefits:
- Lower energy demand of Tertiary Amine based energy efficient CO2 capture process as compared to conventional process.
- Lower expected cost of Methanol produced from full scale FG-CTM plant than the present commercial cost of methanol.
- This CO2 to Methanol conversion plant shall be a unique plant, globally, where CO2 shall be drawn from waste flue gas of a coal fired power plant and shall be converted to methanol thru a catalytic hydrogenation process. It will also create a potential new business avenues and revenue stream for NTPC.
