The use of computer code that could predict spatial flow-dynamics of pollutant with time is needed to control air pollution such as that in Sicily, Italy, where there is a serious health dangerous gaseous emission health problem due to the presence of many petrochemical facilities. A three-dimensional computer code based on the finite volume concept in Cartesian Coordinate system was applied and tested by experimental emission data from sulfuric acid manufacture in AGIP-Gela petrochemical plant. The simulation was performed by calculating the following: geometry problem by DELTA-B code, one-dimensional velocity, three-dimensional steady state wind field, and three-dimensional dispersion. Simulation results showed that in the case of plant failure, SO2 levels would exceed the alarm limit, i.e., up to > 500 μg/cu m, which is twice that forecasted by law limits. It could take only 1500 sec for the health dangerous polluting levels to reach Gela City's inhabited areas.

Abstract
The use of computer code that could predict spatial flow-dynamics of pollutant with time is needed to control air pollution such as that in Sicily, Italy, where there is a serious health dangerous gaseous emission health problem due to the presence of many petrochemical facilities. A three-dimensional computer code based on the finite volume concept in Cartesian Coordinate system was applied and tested by experimental emission data from sulfuric acid manufacture in AGIP-Gela petrochemical plant. The simulation was performed by calculating the following: geometry problem by DELTA-B code, one-dimensional velocity, three-dimensional steady state wind field, and three-dimensional dispersion. Simulation results showed that in the case of plant failure, SO2 levels would exceed the alarm limit, i.e., up to > 500 μg/cu m, which is twice that forecasted by law limits. It could take only 1500 sec for the health dangerous polluting levels to reach Gela City's inhabited areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
