calcEF_SO2.Rd
Calculates the appropriate sulfur dioxide (SO2) emission factor (g/kWh) for the given parameters.
calcEF_SO2( engineType, location, loadFactor = NULL, ECAfuelSulfurPercentage = 0.1, GlobalfuelSulfurPercentage = 0.5, main_aux_boiler = "main" )
engineType | Engine type (vector of strings) (see
|
---|---|
location | Location of vessel (vector of strings). Valid values are:
|
loadFactor | Fractional percentage (between 0 and 1) of main engine required to propel vessel at given speed (vector of numericals) (see ShipPowerModel library). This parameter is optional. By default, it is not used and the resulting emission factor is independent of engine load. |
ECAfuelSulfurPercentage | Fuel sulfur cap (percentage by weight) for the Emissions Control Area (ECA). Default = 0.1% (in effect Jan. 1, 2015) |
GlobalfuelSulfurPercentage | Fuel sulfur cap (percentage by weight) for outside the Emissions Control Area (ECA). Default = 0.5% (in effect Jan. 1, 2020) |
main_aux_boiler | Is this calculation for a propulsive (main), auxiliary (aux), or boiler engine? Options:
|
EF_SO2
(g/kWh) (vector of numericals)
Location is important for determining the fuel being used, as fuel sulfur requirements and type of fuel typically used vary by location.
For more information about calculating SO2 emission factors, see Section 3.5.7 of the Port Emissions Inventory Guidance.
