What is the emission factor for diesel fuel?
2 Fuel-Specific Greenhouse Gas Emission Factors
| Fuel | Carbon emission factor (tC/TJ) | Carbon emission factor (tCO2/TJ) |
|---|---|---|
| Gas/diesel oil | 20.2 | 74 |
| Residual fuel oil | 21.1 | 77 |
| LPG (liquid petroleum gas) | 17.2 | 63 |
| Ethane | 16.8 | 62 |
What is mobile combustion sources?
Mobile combustion means emissions from the transportation of materials, products, waste, and employees resulting from the combustion of fuels in company owned or controlled mobile combustion sources (e.g., cars, trucks, buses, trains, airplanes, ships, etc.). Sample 1.
What is calorific value of diesel?
It is the amount of heat energy produced on complete combustion of 1 kg of fuel. The calorific value of a fuel is expressed in a unit called kilojoule per kg (kJ/kg)….For Diesel LCV = 44.6 MJ/kg and HCV = 46 MJ/kg.
| Fuel | Calorific Value(approx) (kJ/kg) |
|---|---|
| Coal | 25000-33000 |
| Petrol | 47000 |
| Kerosene | 46000 |
| Diesel | 45000 |
What is electricity emission factor?
The weighted average emission factor describes the average CO2 emitted per unit of electric- ity generated in the grid. It is calculated by dividing the absolute CO2 emissions of all power stations in the region by the region’s total net generation.
What are the different types of emissions?
There are many sources of emissions. These have been grouped into four categories: point, mobile, biogenic, and area. Point sources include things like factories and electric power plants.
How is CO2 emission factor calculated?
Carbon dioxide emissions per therm are determined by converting million British thermal units (mmbtu) to therms, then multiplying the carbon coefficient times the fraction oxidized times the ratio of the molecular weight of carbon dioxide to carbon (44/12). 0.1 mmbtu equals one therm (EIA 2018).
How are diesel engine emissions calculated?
Report actual emissions in tons/year. Calculate actual emissions using one of the following methods: If the emission factor is in units of pounds per quantity of fuel (gallons or cubic feet): Actual emissions (tpy) = Emission Factor (lb/unit) x Actual Annual Fuel Use (unit) x ([100 – Control Efficiency] รท 100)
What is the specific carbon content of diesel?
Fuels for transport
| Fuel | Net CV | Carbon content |
|---|---|---|
| MJ/kg | % | |
| Petrol | 44 | 87 |
| Diesel | 42.8 | 86 |
| LPG (mainly propane) | 46 | 82 |
What pollutants come from mobile sources?
Mobile sources (e.g., trucks, buses, passenger cars, construction equipment, locomotives, and other types of vehicles) are major contributors to air pollution in the Northeast states because they emit smog-forming pollutants such as nitrogen oxides (NOx) and hydrocarbons (HC) as well as particulate matter (PM), toxics.
How does mobile sources cause air pollution?
Nitrogen Oxides: Nitrogen oxides form when fuel burns at high temperatures, such as in motor vehicle engines. Mobile sources are responsible for more than half of all nitrogen oxide emissions in the United States. Both on-road and non-road mobile sources are major nitrogen oxide polluters.
