Abstract

Emission of volatile organic compounds (VOCs) from many industrial wastewater treatment facilities are a major source of air pollution, and getting much attention from EPA. In order to determine "Best Available Control Technology" and "Lowest Achievable Emission Rate" for controlling emissions of VOCs from industrial wastewater, the accurate estimation of VOCs emission rate and realistic modeling of contaminant volatilization are required.

In this research, the volatilization of three compounds (Toluene, Xylene, and Aniline) were studied under varying aeration, stirring, and quiescent scenarios. The concentrations of contaminant were analyzed by HPLC. Experimental rate constants were obtained by using the first order reaction kinetics. Activity coefficients were calculated using UNIFAC program, then theoretical rate constants were evaluated from a model based on the Henry's Law.

For all three compounds, the experimental rate constants were less than the theoretical ones, and the difference between experimental rate constant and theoretical rate constant increases as the flowrate increases.
