An integrated tool to forecast and reduce refinery contribution to SO2 pollution peaks
For many plants, the annual average impact is significantly lower than the regulation limit. Nevertheless, in some critical meteorological conditions, pollution peaks may occur. The present study describes an original control method for refinery emissions based on meteorological forecast and dispersion modelling, to avoid SO
2pollution peaks. An integrated operational tool has been developed to forecast, automatically, 24 h a day, the environmental SO
2impact around the plant for the next two days. The operational system allows the site to avoid the major part of pollution peaks and the associated cost.
