Alter NRG Integrated Plasma Gasification Solution

Alter NRG PLasma Gasification Solution will increase revenues, decrease operational risks and provide superior environmental performance versus other technologies. We are the only company with commercial reference facilities.

 

The table below details the numerous benefits of Westinghouse Plasma Corp. gasification technology versus incineration for the treatment of MSW.

Westinghouse Plasma Corp. Gasification Technology

Incineration

Feedstock Flexibility Ability to mix feedstocks such as:

  • MSW
  • Industrial Waste
  • Commercial & Industrial Waste
  • Hazardous Waste
  • Tires Waste
  • Biomass Fuels (such as wood waste)
MSW and other common waste streams
Fuel Created Syngas (Carbon Monoxide and Hydrogen) Not applicable
End Product Opportunities
  • Replacement Fuel for Natural Gas and Fuel Oil
  • Power via Steam cycle
  • Power via Combined cycle or Reciprocating Engines
  • Power via Fuel Cells (future)
  • Process Steam
  • Liquid Fuels (ethanol, bio-diesel)
  • Hydrogen
  • Fertilizer Compounds
  • Power via Rankine Cycle (Steam Cycle)
  • Process Steam
Overall Plant Efficiency Combined Cycle Process: 1 tonne of municipal solid waste is capable of creating 1000 kWh of power via combined cycle configuration Steam Cycle Process: 1 tonne of municipal solid waste generates between 500-650 kWh of power
Emissions Combined Cycle Process:

  • Nitrogen Oxide (NOx): <36 ppmvd
  • Sulfur Dioxide (SO2): <1.05 ppmvd
  • Mercury (Hg): <1.4 μg/dscm²
  • Nitrogen Oxide (NOx): 110-205 ppmvd
  • Sulfur Dioxide (SO2): 26-29 ppmvd
  • Mercury (Hg): 28-80 μg/dscm²
Dioxins and Furans High operating temperature (>1000°C) in conjunction with an oxygen starved environment destroys any dioxins/furans that may be present in the feedstock, and eliminates the potential for the creation of dioxins/furans.  Rapid syngas cooling via water quench prevents de-novo synthesis of dioxins and furans. The presence of oxygen, chlorine, and particulate creates the right conditions for the formation of dioxins and furans.
Byproduct Inert, non-hazardous and non-leaching glassy slag salable as an aggregate building product. Most particulate recovered during cleaning of the syngas is recyclable. Hazardous fly ash and scrubber residues plus incinerator bottom ash

Other Plasma Technologies

Commercial Reference Plants Three commercial references.  Two others under construction. Most have no commercial reference plants.
Operational Experience Greater than ten years None, except that some competitors have experience at small demonstration plants
Demonstration Plant Yes, up to 24 tpd Some competitors have a demonstration plant.  Some are at lab scale.  Some do not have a demonstration plant.
Plasma Gasifier Design Simple single vessel design Most competitors employ a multi-step design.
Plasma Torch Technology 30 years experience. Developed and owned by Westinghouse Plasma Corp. Must be purchased.  No expertise in plasma torches.
Scale Up to 1000 tpd in a single vessel.  Continuous feeding. Up to 150 tpd for some competitors.  Some competitors use batch feeding.

Non-Plasma Gasification Technologies

Syngas Quality Tar free syngas suitable for clean-up to specifications required by gas turbines, reciprocating engines, liquid fuel technologies and fuel cells. Syngas must be immediately combusted before being cleaned.
Feedstock Flexibility Ability to mix feedstocks such as:

  • MSW
  • Industrial Waste
  • Commercial & Industrial Waste
  • Hazardous Waste
  • Tires Waste
  • Biomass Fuels (such as wood waste)
Limited ability to process waste streams other than MSW.Lower temperatures limit feedstock flexibility
End Product Opportunities
  •  Replacement Fuel for Natural Gas and Fuel Oil
  • Power via Steam cycle
  • Power via Combined cycle or Reciprocating Engines
  • Power via Fuel Cells (future)
    Process Steam
  • Liquid Fuels (ethanol, bio-diesel)
  • Hydrogen
  • Fertilizer Compounds
Power via Steam cycle Process Steam
Byproduct Inert, non-hazardous and non-leaching glassy slag salable as an aggregate building product. Most particulate recovered during cleaning of the syngas is recyclable Similar to incineration – hazardous fly ash and scrubber residues plus bottom ash.
