Abstract

Fugitiveemissions are not an environmental concern alone, but are also a health concern. From occupational health standpoint, fugitiveemissions are the main sources of origin of the continuous exposure to workers. Operating plants regularly measure release and concentration levels through a plant-monitoring program. However, for processes which are still ‘on paper’, predictive estimation methods are required. Therefore, three methods for estimating concentration of the fugitiveemissions are presented for the process development and design phases of petrochemical processes. The methods estimate the fugitiveemission rates and plant plot dimensions resulting to fugitiveemissionconcentrations. The methods were developed for the type and amount of information available in three processdesign stages; conceptual design, preliminary processdesign, and detailed processdesign. The methods are applied on a real benzene plant; the estimated benzene concentrations are compared to the actual concentration measured at the plant. The results show that as the information mounts up during design, the concentration estimate becomes more accurate. The results indicate that the methods presented provide simple estimates of fugitiveemission-based concentrations during the design stages.
