Stationary combustion by carbon content

[/business/energy/stationaryCombustion/carbon]

The category /business/energy/stationaryCombustion/carbon contains provides emissions calculations for stationary fuel combustion based on the carbon content of fuels. This methodology is described in the technical guidelines published in association with the US Environmental Protection Agency's (EPA) Mandatory Greenhouse Gas Reporting rule.

This category offers two broad options for calculating:

using default values for the proportion of carbon within specific fuels
using user-specified carbon content value

In the latter case, the calculation equates to the Tier 3 methodology recommended under the EPA's mandatory reporting guidelines.

Default values for fuel carbon content are sourced from the EPA guidelines for Suppliers of Petroleum Products as well as the American Petroleum Institute Compendium of Greenhouse Gas Emissions Methodologies for the Oil and Gas Industry which contains data aggregated from several sources including the EPA and the Energy Information Administration (EIA).

How to use this category

To use this category, select a fuel type using the type and subtype drill choices.

Next, the quantity of fuel must be specified. There are three options for making this specification.

Mass-based calculations

To calculate on the basis of mass, specify a quantity using the mass profile item value. This method is suitable for solid and liquid phase fuels.

Volumetric calculations using fuel density

To calculate on the basis of volume, specify a quantity using the volume profile item value, together with the density of the fuel using the density. This method is suitable for liquid and gas phase fuels.

Volumetric calculations for gases

An alternative way to calculate on the basis of volume - appropriate specifically to gaseous fuels - is to specify a quantity using the volume profile item value, together with the the molecular weight (molecularWeight) of the fuel and a molar volume conversion factor (molarVolumeConversionFactor). The latter simply represents the volume occupied by a single mole of the respective gaseous fuel.

In all cases, the returned value represents the CO₂ emissions resulting from the burning of the specified quantity, using the default value for carbon content. To specify the carbon content of the fuel, set the carbonContent profile item value accordingly. The value should be expressed as a full percentage, i.e. between 0-100. If specified, CarbonKit will use this value in the calculation of CO₂ emissions rather than the default for the respective fuel type.

All calculations assume 100% combustion, following EPA guidelines.
