The Impact of PG Classes and Addition of FGDB on Air Pollution Emitted from Shuaibah III (IWPP) Plant: Screening Model.

The objective of the present work is the studying of air quality that contained pollutant gases (SO₂, NO_x, CO), and PM released from the Shuaibah III (IWPP) plant as a case study. Also, we tried to evaluate the effect of Flue gas desulfurization byproduct (FGDB) on SO₂ that turned into carried out within the studied place. For the determination of dispersion, the source of pollution was taken into consideration to be in a rural area. The screening model was used to calculate concentrations dispersion of gas pollutants at different Pasquill-Gifford stability classes' conditions. The levels C_max (maximum concentrations) decreased from A-class to F-class, and the influence distance D_max (maximum distance of downwind concentrations) quickly grows. The SO₂ dispersion became affected by the FGDB system. The results confirmed that the C_max of air pollutants released from the stack may additionally decreases than the Saudi Arabian standard.
