Notes

Propane is stored as a liquid under moderate pressure at ambient temperature. It offers good energy density and relatively clean combustion characteristics compared to heavier hydrocarbons.

Definitions

‘Lower Heating Value’

Heat of combustion excluding latent heat of water vapor

‘Global Warming Potential’

Relative measure of heat trapped in atmosphere compared to CO2

‘Surrogate Model’

Simplified single-component representation using pure propane

Major Assumptions

  • Surrogate model uses pure propane

  • Air composition is standard atmospheric
