Syn Gas and Synthetic Natural Gas

  1. 1. Syn Gas, Synthetic Natural Gas SNG Hameed Akhtar 2k10-Che-155
  2. 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. 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. 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. 5. Electricity Generation ● SNG works in existing natural gas generators and turbines ● Can provide flexible low capital cost biomass power
  6. 6. SNG NH3 Gas Turbine Fisher Tropsh Syngas Uses of Syngas
  7. 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)
  8. 8. Coal Biomass Wood Misc Sources of Syngas
  9. 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. 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
