Definitions

  • the subject matter relates generally to processes, systems, and facilities for converting municipal solid wastes (MSW) into fuel.
  • MSW municipal solid wastes
  • MSW Municipal solid waste
  • Municipal solid waste includes all solid materials disposed by municipalities. While some of this waste is recycled, the majority is typically dumped in landfills, where it decomposes over a period of decades or even centuries. It has been recognized that municipal solid waste contains organic materials that have energy content. If MSW is left untreated in landfills, the energy content can be drained slowly from the landfill by bacterial processes, which not only dissipate the concentrated energy but, also, produce methane, a strong greenhouse gas. Some landfills have sought to collect methane, which may be used for fuel; however, the conversion to methane takes place on long time scales and is rather ineffective in recovering much of the available energy content of the MSW.
  • Incineration includes the combustion of MSW or refuse-derived fuel (RDF) to produce heat, which typically powers a turbine to produce electricity.
  • RDF refuse-derived fuel
  • Byproducts of incineration include fly ash, bottom ash, and flue gases containing pollutants including sulfur compounds, C02, which is a green-house gas, acid gases as well as metals, metal compounds and particulates. Fly ash, when collected, and bottom ash are typically discarded in landfills.
  • Pyrolysis involves heating the organic portions of the MSW to the point that thermally unstable compounds are chemically decomposed into other compounds. Those compounds mix with other volatile components to form a pyrolysis gas that typically includes tars, alkenes, aromatic hydrocarbons, sulfur compounds, steam, and carbon dioxide.
  • the solid residues from pyrolysis include coke (residual carbon), which can be burned or used as a gasification feedstock.
  • a related method for recovering energy from MSW is gasification.
  • Gasification involves converting at least a fraction of the MSW into a synthesis gas ("syngas') composed mainly of carbon monoxide, carbon dioxide, and hydrogen.
  • Syngas' a synthesis gas
  • Gasification technology has existed since the nineteenth century, when coal and peat were gasified into "town gas” that provided a fiammable mix of carbon monoxide (CO), methane (CH 4 ) and hydrogen (H 2 ) that was used for cooking, heating and lighting.
  • CO carbon monoxide
  • CH 4 methane
  • H 2 hydrogen
  • biomass and coal gasifies were used to produce CO and H 2 to meet transportation needs.
  • some of the syngas was converted directly in to liquid transportation fuels using the Fisher-Tropsch process.
  • Gasification has been applied directly to the MSW but, in other cases, the MSW is first pyrolyzed, and then subjected to a secondary gasification process.
  • Gasification of MSW generally includes a mechanical processing step that removes recyclables and other materials that have low or no energy content. Then, the processed MSW feedstock is heated in a gasifier in the presence of a gasification agent (including at least some oxygen and possibly steam).
  • a gasification agent including at least some oxygen and possibly steam.
  • Gasifiers can have a number of configurations. For example, fixed-bed gasifiers place the feedstock in a fixed bed, and then contact it with a stream of a gasification agent in either a counter-current ("up draft") or co- current (“down draft”) manner. Also, gasifiers may use fluidized bed reactors.
  • Another method of gasifying MSW is treatment in the presence of oxygen with a high- temperature plasma. Such systems may convert the MSW to syngas, leaving vitrified wastes and metals as byproducts.
  • the Environmental Protection Agency (EPA) in the United States has mandated a Renewable Fuel Standard ("RFS") under which cellulosic-based fuels generate Cellulosic RINs (renewable identification numbers) which are a form of compliance credits for Obligated Parties (e.g., refineries). Under the RFS, the Obligated Parties are required to blend cellulosic fuel into fossil-derived fuels.
  • RFS Renewable Fuel Standard
