Landfill Gas Enrichment Impact at Net Caloric Value

Gas enrichment at liquid-wall interfaces.

Molecular dynamics simulations of Lennard-Jones systems are performed to study the effects of dissolved gas on liquid-wall and liquid-gas interfaces. Gas enrichment at walls, which for hydrophobic walls can exceed more than 2 orders of magnitude when compared to the gas density in the bulk liquid, is observed. As a consequence, the liquid structure close to the wall is considerably modified, le...

Landfill Gas System Considerations at High-btu Landfills

There are generally three broad categories of landfill-gas-to-energy (LFGTE) projects: electric power generation, medium-BTU industrial fuel; and high-BTU pipeline gas. During initial feasibility studies, landfill owners and developers should weigh the advantages of each with regard to the technology, local markets, landfill conditions, and site proximity to potential users. There has been an i...

Landfill-gas-to-Energy projects: analysis of net private and social benefits.

Methane emissions from municipal landfills represent 3% of the total United States greenhouse gas emissions that contribute to climate change. These methane emissions can be released to the air or collected and flared. This landfill gas also has the potential to be used to generate electricity. In 1994,the Environmental Protection Agency(EPA) created the Landfill Methane Outreach Program, with ...

Characterization of Landfill Sites in Brazil for Landfill Gas Recovery

Beneficial Use of Landfill Gas

1 page only) With regulatory and environmental pressure toward control of landfill gas (LFG) management of collected LFG has become a significant issue. At a minimum, collected LFG must be flared for control of methane and nonmethane organic compounds. Beneficial reuse of LFG as an alternative to combustion has tremendous potential at most landfills. Issues facing reuse of LFG include gas compo...
