  5. Process Specifications
    1. 5,500 mt/day sub-bituminous coal processed into syngas and catalytically converted to methane
    2. 2 + 1 gasification trains
    3. Feedstock: 5,500 tpd sub-bituminous coal, up to 20% petcoke blend
    4. Process: coal gasification of coal – heat recovery – dust collection – water gas production – desulfurization/separation of CO₂ – SNG synthetic – drying/compressing – SNG product
  6. Features
    1. Methane production in 2nd stage results in smaller shift, AGR and methanation units
    2. HP steam coupled with process heat from methanation enhances thermal efficiency
    3. Long operating experience with petroleum coke and sub-bituminous coal at world scale
    4. Low start-up emissions
    5. Higher capacity trains
    6. Lower carbon slag product
    7. Leverages Ky NewGas design experience
    8. E-Gas™ technology enhancements improve SNG project economics
    9. Builds on lengthy E-Gas™ operating experience processing petcoke, sub-bituminous coal and bituminous coal
