Propane is used for a wide variety of applications such as heating, shrink wrapping, soldering, heat treatment and it is often used as a substitute for dissolved acetylene when carrying out flame-cutting processes.
Propane (C3H8) is a colourless and highly flammable liquefied gas – although it has the lowest flammability range of any of the commonly available fuel gases. As a constituent of natural gas, it is obtained by refining and processing natural gas. Propane is heavier than air, with both a primary and secondary flash temperature. It is one of the main components in liquid petroleum gas (LPG) along with butane. As the ratios of these LPG gases vary from one supplier to another, the flame properties can also differ.
Applications and use:
- car fuel
- industrial and domestic heating
- oxy-propane cutting and brazing
- soldering, preheating, heat treatment
- shrink wrapping
- heating greenhouses and livestock sheds
- flame-weeding and pest control
- substitute for dissolved acetylene when carrying out flame-cutting processes
It is also employed in its pure form as the fuel gas in flame photometers.
As a specialty gas, it is used in mixtures to calibrate process control analyzers in the petrochemical industry. It is also employed as a refrigerant and in refrigerant blends and as an aerosol propellant. Other applications include controlled atmospheres in metallurgy, the production of various chemicals, efficiency testing of gas burners and engines and calibration gas mixtures.
