Fugitive Emissions of VOCs from Industrial Sewer Networks: Integration of naUTilus and ArcViewBy Cindy Fee Ha How, M.S.E., Richard L. Corsi and David R. Maidment ABSTRACT The adoption of the 1990 Clean Air Act amendments brought increasing regulatory attention to on-site industrial sewers as a source of volatile organic compound (VOC) emissions. The goal of this research was to link the FORTRAN model, naUTilus, to GIS technology in order to facilitate prediction of VOC emissions from large industrial sewer networks. The connection of naUTilus with a GIS software package, ArcView, was achieved through a series of Avenue scripts. The integrated naUTilus/GIS model was used to predict VOC emissions from actual industrial sewer systems under varying environmental, flow, and sewer conditions. Stripping efficiency was predicted to (1) increase with increasing wind speed, (2) increase with increasing temperature (liquid and ambient), (3) decrease with increasing liquid flow rates, and (4) decrease with an increasing number of sealed drains. The integrated model was also used to analyze emissions estimates on a spatial level. Ventilation patterns assumed in the naUTilus model were found to have a significant effect on predicted emissions.
