Estimating VOC Emissions from Waste Water Treatment Units Using a Flow-Through Flux Chamber and Chemdat7


Book Description

There is increasing concern in the petroleum industry for a practical method of accurately quantifying refinery volatile organic compound (VOC) emissions. The U.S. Environmental Protection Agency (EPA) developed the Chemdat7 emission rate model to predict VOC emissions from surface impoundments, waste-water treatment plants, and land farms for regulatory purposes. Previous studies have indicated that Chemdat7 significantly overpredicted VOC emissions. Much of the model evaluation of Chemdat7 used the EPA isolation environmental flux chamber. There are some concerns in using the EPA isolation flux chamber for measurement of fugitive emissions from surface impoundments due to its effect on ambient wind velocity, temperature, and solar radiation. This paper discusses an alternative method for quantifying VOC emissions from waste-water treatment units using a flow-through environmental flux chamber, and includes a comparison of the results from the flow-through chamber with that of the Chemdat7 model.

Volatile Organic Compound Emissions from USAF Wastewater Treatment Plants in Ozone Nonattainment Areas


Book Description

In accordance with the 1990 Clean Air Act Amendments (CAAA), this research conducts an evaluation of the potential emission of volatile organic compounds (VOCs) from selected Air Force wastewater treatment plants. Using a conservative mass balance analysis and process specific simulation models, volatile organic emission estimates are calculated for four individual facilities--Edwards AFB, Luke AFB, McGuire AFB, and McClellan AFB--which represent a cross section of the current inventory of USAF wastewater plants in ozone nonattainment areas. From these calculations, maximum facility emissions are determined which represent the upper limit for the potential VOC emissions from these wastewater plants. Based on the calculated emission estimates, each selected wastewater facility is evaluated as a potential major stationary source of volatile organic emissions under both Title I of the 1990 CAAA and the plant's governing Clean Air Act state implementation plan. Next, the potential impact of the specific volatile organics being emitted is discussed in terms of their relative reactivity and individual contribution to tropospheric ozone formation. Finally, a relative comparison is made between the estimated VOC emissions for the selected wastewater facilities and the total VOC emissions for their respective host installations.
