Development of a plume-in-grid model for industrial point and volume sources: application to power plant and refinery sources in the Paris region
Plume-in-grid (PinG) models incorporating a host Eulerian model and a subgrid-scale model (usually a Gaussian plume or puff model) have been used for the simulations of stack emissions (e.g., fossil fuel-fired power plants and cement plants) for gaseous and particulate species such as nitrogen oxide...

| description | Plume-in-grid (PinG) models incorporating a host Eulerian model and a
subgrid-scale model (usually a Gaussian plume or puff model) have been used
for the simulations of stack emissions (e.g., fossil fuel-fired power plants
and cement plants) for gaseous and particulate species such as nitrogen
oxides (NO<sub>x</sub>), sulfur dioxide (SO<sub>2</sub>), particulate matter (PM)
and mercury (Hg). Here, we describe the extension of a PinG model to study
the impact of an oil refinery where volatile organic compound (VOC) emissions
can be important. The model is based on a reactive PinG model for ozone
(O<sub>3</sub>), which incorporates a three-dimensional (3-D) Eulerian model and a
Gaussian puff model. The model is extended to treat PM, with treatments of
aerosol chemistry, particle size distribution, and the formation of secondary
aerosols, which are consistent in both the 3-D Eulerian host model and the
Gaussian puff model. Furthermore, the PinG model is extended to include the
treatment of volume sources to simulate fugitive VOC emissions. The new PinG
model is evaluated over Greater Paris during July 2009. Model performance is
satisfactory for O<sub>3</sub>, PM<sub>2.5</sub> and most PM<sub>2.5</sub> components. Two
industrial sources, a coal-fired power plant and an oil refinery, are
simulated with the PinG model. The characteristics of the sources (stack
height and diameter, exhaust temperature and velocity) govern the surface
concentrations of primary pollutants (NO<sub>x</sub>, SO<sub>2</sub> and VOC). O<sub>3</sub>
concentrations are impacted differently near the power plant than near the
refinery, because of the presence of VOC emissions at the latter. The
formation of sulfate is influenced by both the dispersion of SO<sub>2</sub> and the
oxidant concentration; however, the former tends to dominate in the
simulations presented here. The impact of PinG modeling on the formation of
secondary organic aerosol (SOA) is small and results mostly from the effect
of different oxidant concentrations on biogenic SOA formation. The
investigation of the criteria for injecting plumes into the host model (fixed
travel time and/or puff size) shows that a size-based criterion is
recommended to treat the formation of secondary aerosols (sulfate, nitrate,
and ammonium), in particular, farther downwind of the sources (beyond about
15 km). The impacts of PinG modeling are less significant in a simulation
with a coarse grid size (10 km) than with a fine grid size (2 km), because
the concentrations of the species emitted from the PinG sources are
relatively less important compared to background concentrations when injected
into the host model with a coarser grid size. |
