Syn Gas and Synthetic Natural Gas
- 1. Syn Gas, Synthetic Natural Gas SNG Hameed Akhtar 2k10-Che-155
- 2. Synthetic Natural Gas • Synthetic natural gas, is a fuel gas that can be produced from fossil fuels such as lignite coal or from biofuels around 85% methane, • Syngas is an abbreviation for synthesis gas, which is a mixture comprising of carbon monoxide, carbon dioxide, and hydrogen. • The syngas is produced by gasification of a carbon containing fuel to a gaseous product that has some heating value. • Clean Synthesis Gas is free of acid gases. • Clean Synthesis Gas is widely applicable.
- 3. SNG Offers Energy efficient biofuel production Second generation biofuel Transportation, heating and power generation fuel Low emissions Existing infrastructure Integration with Wind, Water Solars through Renewable Power Methane.
- 4. Low BTU Gas • 150-300BTU/ft3 Basic Syngas Produced by air fed gasifier which contains 35-50% nitrogen, but suffices as normal industrial heating fuel Medium BTU gas • 300-500BTU/ft3 higher grade syngas produced by ooxygen fed Gasifier which requires a dedicated oxygen plant High BTU SNG • 1000-1400BTU/ft3 this gas requires a shift reactor to upgrade the Gas Catagories of Coal Syngas
- 5. Electricity Generation ● SNG works in existing natural gas generators and turbines ● Can provide flexible low capital cost biomass power
- 7. Uses of Synthetic Natural Gas • Transportation • Electricity generation • Domestic • Industrial (Ammonia Manufacture) Natural gas buses are widely used ● 150 units in Canada Source: Marbek (2010)
- 9. Coal Gasification Technologies • Basic Overview of gasification • Coal or other fuels • Oxidation carefully controlled • H2, CO2, CH4, other products • H2 can be purified • Ash/slag leftovers • 3 types of gasifiers • Moving bed • Fluid Bed • Entrained Flow • Underground Coal Gasification • Vertical wells and pathway creation • Controlled retraction injection point
- 10. Synthetic Natural Gas Across the Globe America • Sundrop Fuels • Rentech Europe • Güssing • GoBiGas project approximately 930 dry tons per day of woody biomass. Fuel Capacity 8MW
