C4 - Transforming CO2 into a commercial product
- 1. 1 Geothermal CO2 production Souheil Saadi, sosa@topsoe.com, +45 6192 6627 Transforming CO2 into a commercial product
- 2. 2 CO2 demonstration plant A holistic solution developed with HS Orka at Svartsengi Geothermal Resource Park
- 3. 3 Emissions Management Haldor Topsoe provides a full range of products and services for a broad range of chemical processing, hydro processing, and emissions management processes Chemical Processing Hydroprocessing Ammonia Syngas Methanol Hydrogen SNG Sulfuric acid Dimethyl ether Formaldehyde Gasoline synthesis Naphtha Kerosene Diesel VGO Resid Sulfur removal NOx & CO removal VOC abatement Particulate filtration Process design, Engineering, & licensing High-performance catalysts+ Proprietary equipment+ Business & technical services+ Over 300 size and shape variations
- 4. Geothermal Resources Non-condensable gases From Waste to Resource
- 5. 5 Geothermal Resources Non-condensable Gas (NCG) Valorization • Carbon Dioxide, Hydrogen, Hydrogen Sulfide and Methane • Silica impurities in gas phase • CO2 and H2 are the most obvious candidates • H2 is a fuel or chemical • CO2 for CO or Methanol production • CO2 for greenhouses, food- and beverage industry • Excess H2S may be converted to fertilizer • CO2 for green house growth enhancement • Tonnage needed • Gas quality • Value
- 6. 6 Methanol Technology Using CO2 to boost methanol production • 3CH4 + CO2 + 2H2O = 4CH3OH M = 2 • 3C2H6 + CO2 + 5H2O = 7CH3OH M = 2 • For a typical natural gas, the optimal CO2 content for methanol production is ~25 mole% or less • One-step plant owners profits from revamp with CO2 import • Capacity boost (up to 20%) • Improved energy consumption (3-4% reduction) • Reduced CO2 emission (16% reduction)
- 7. Haldor Topsoe Gas Conditioning Technology
- 8. 8 The H2S pain • Legislation • Odor control • Fuel penalty if thermally oxidized • Obstacle for valorization of other gas components • CO2 production • Gas engines • Dilute acid production
- 9. 9 Installation and reactor design Topsoe SMC™ catalysts: Compact and modular • Ideal for Remote locations • Ideal for lean H2S gas • Conversion >99.9% • Selectivity to SO2 >99% • Simple installation and operations Grid Installed
- 10. 10 Mapping the operational window • Low gas temperature or O2 levels induces Sº formation • High gas temperature or O2 levels reduces SO2 selectivity • High H2S conversion • High selectivity to SO2 0% 1% 2% 3% 4% 5% 6% 150 200 250 300 350 400 450 O2(%) Temperature (°C) Sel. SO2 >99.5% Conv. H2S >99.5% Tested for: H2S, CS2, COS, RSH H2, CO, HC, BTX, etc. S0 SO3 O2 + H2S SO2 + H2O Sulfur Monolith Catalyst SMC™
