Landfill gas emission rate measurement using an emission isolation flux chamber

Abstract

This paper presents the results of the final phase of a research grant sponsored by the Florida Center for Solid and Hazardous Waste Management (FCSHWM) to quantify air emissions from municipal solid waste (MSW) landfills. In preceding phases of this project, an enclosure device, or emission isolation flux chamber, was designed to sample gaseous emissions from a finite surface area of the landfill to provide for a direct method of mass emission rate measurement. Recommendations from the pilotscale study and field operation of the flux chamber have facilitated the design of an improved flux chamber, which was constructed during this research. The new flux chamber was tested on a simulated subsurface emission source (soil-cell) to optimize its performance prior to operation in the field. The objectives of this research program were: 1) to design an improved flux chamber that could be used to accurately measure landfill gas (LFG) emission rates, 2) perform extensive field measurements at a minimum of one landfill site, using the flux chamber, to examine spatial and temporal variations in LFG emission rates, and 3) characterize the flux chamber's ability to account for these variations. An emphasis was placed upon exploring the correlation of gas emission rates to the exogenous independent variables, air temperature, barometric pressure, and rainfall events. If the flux chamber can account for variations in LFG emission rates, then emission rate values representative of the entire landfill could be used in area source dispersion models to determine concentrations of various pollutants in the ambient air near MSW Landfills.
