Sierra Energy is the original equipment manufacturer (OEM) of the FastOx Gasifier. As part of this equipment package, a project developer would receive:

• A technology license.
• Major equipment (vessels, feedequipment, and slag removal).
• Burners and oxygen/steam lances.
• Automation and controls.
• Commissioning assistance and operator training.

• Selection of waste heat boiler or direct quench will be based on project heat integration study.
• The waste heat boiler will be supplied by a specialist vendor.
• The techno-economic analyses offered by Sierra Energy, as part of its engineering package, will support developers in making these decisions.

• The waste cleaning section removes tar and soot from the raw syngas exiting the gasifier.
• The multi-stage gas cleaning configuration is specified in Sierra Energy’s process design package (PDP).
• The gas cleaning section uses commercially available equipment from 3rd party vendors.
• The soot removed from the syngas is recycled to the gasifier.

• The developer is responsible for engineering and designing equipment upstream and downstream of the FastOx Gasification Isle.

The project developer is responsible for ensuring feedstock is adequately prepared for the FastOx gasification process.

• Waste entering the gasifier should be between 0.5 and 2 inches (12mm to 50mm) in size.
• Feedstock up to 20% moisture typically does not require pre-drying.
• Ash content below 15% is best for efficiency.
• Feedstock lower heating value above 12-15 MJ/kg (dry basis) is ideal.
• Heterogenous waste streams including blends of different waste sources are acceptable.

• The developer is responsible for the end-product technology.
• Sierra Energy will work with the developer to ensure syngas meets required specifications.
• Common end-products include hydrogen, methanol, renewable natural gas, and electricity.
