Carbon Capture & Sequestration (Storage) CCS Basudha Maurya Department of Chemical Engineering MNNIT, Allahabad vasundhre@gmail.com
2 Presentation Outline Introduction CO2 Capture Processes & Separation Technologies CO2 Transportation & Storage Quality Specification of CO2 Monitoring & Mathematical expressions CCS Status in World & in India Alternative Approaches to Capture CO2
3 By 2050, global population will rise from & the World energy demand is expected to increase by 50% over the next 20 years.
4 We Still Rely on Fossil Fuels Fossil fuels (coal, gas and oil) represent 80% of the global energy supply Renewables supply only account for 13% of our total energy supply
5 and will Continue to do so for Decades to Come By 2030 Renewables could make upto 30% of the global energy supply But fossil fuels will remain our main source of energy for decades to come
6 Fossil Fuels Power the Largest Emitters of CO2. Fossil fuels power plants, heavy industry and refineries account for 52% of the worlds current CO2 emissions (15 billion tonnes CO2 emissions/year)
7 CO2 emissions by industry & power plant EU GEOCAPACITY 2006
8 CO2 emissions by region EU GEOCAPACITY 2006
9 and too Much CO2 Leads to Global Warming which in turn, produces climate change Unless the rise in average global temperature is kept below 2属C, devastating and irreversible climate changes will occur. Muir Glacier, August, 2004 Muir Glacier, August, 1941
10 How do we Meet this Challenge? We need to cut CO2 emissions fast as energy consumption continues to rise Our climate depends on it
11 CCS alone will provide up to 20% of the CO2 emission reductions we need to make by 2050. Heres how it works...
12 What Is Carbon Capture and Sequestration (Storage) Three stage process: i. Capturing CO2 at Large & stationary point sources ii. Transporting the CO2 from source to sink, iii. Injecting the CO2 in suited geological reservoir or sinks
13 Inside CCS
14 Carbon Capture Options Capture Processes: 1. Post-combustion :separation CO2-N2 2. Pre-combustion :separation CO2-H2 3. Oxy-fuel combustion :separation O2-N2 Separation technologies: 1. Adsorption 2. Absorption 3. Membrane Separation 4. Cryogenic distillation
15 Separation principles 1.Adsorption: attachment of fluid to a solid surface Solid sorbents :Lime, zeolite, activated carbon 2.Absorption: fluid dissolves or permeates into a liquid Solvents :Aqueous amines and salts Chemical Adsorption Physical Adsorption Chemical Absorption Physical Absorption
16 Separation principles 3.Membrane Separation: separation which makes use of difference in physical/chemical interaction with membrane Membrane provides grater contacting area
