  1. Emerging TechnologyAcid Gas Removal EPA’s Natural Gas STAR Program, Pioneer Natural Resources USA, Inc., and The Gas Processors Association June 17, 2003

  2. New Developments in Acid Gas Removal Technologies • Typical Amine Process • IGT & Uhde Morphysorb® Process • Engelhard Molecular Gate® Process • Comparison

  3. Typical Amine Process Acid Gas Sweet Gas Lean Amine Stripper (Steel) Condenser Contractor (Adsorber) Reflux Pump Reboiler Sour Gas Fuel Rich Amine Heating Medium Flash Tank Exchanger Booster Pump Filter

  4. Morphysorb® Process Clean Gas Lean Solvent Semi Lean Sour Gas Absorber Crude Gas Flash 1 Flash 2 Flash 3 Flash Recycle c. w. c. w.

  5. Morphysorb® Field Test Unit • The process is ready for commercial-scale application • One field test unit at Shell's Exploration and Production facilities in Fandango, Texas, USA • Feed capacity: 1 MMscfd Source: Morphysorb® Process. IGT & Uhde Technology Profile

  6. Molecular Gate® CO2 Feed Compressor Enriched CH4 30 psia 10 psi pressure drop PRODUCT C1, C2 Pressure Swing Absorption FEED High Pressure C1, C2, C3, C4+ CO2, H2O 5 psia TAIL GAS CO2, H2O, C3+, Lost HCs Vacuum Compressor

  7. Tidelands Molecular Gate Unit • First commercial unit started on May 2002 • Separate recycle compressor is required • No glycol system is required • Heavy HC removed with the CO2 • Tail gas used for fuel is a key optimization • 18% CO2 removed to pipeline specifications • C2 + losses makes the applicability site specific Source: http://www.Engelhard.com/documents/CO2%20Removal-1.pdf
