Applications of propane

Propane can be, as well as butane, at low pressure (5 bar) liquefy. Thus, a high volumetric energy density can be achieved. Propane, partially as a mixture of butane, is used for the following applications:

  • mobile energy supply for road construction (Teerkocher), camping (heating, cooking, cooling)
  • stationary power supply for homes that are located away from a natural gas pipeline
  • LPG for motor vehicles
Mixtures of propane and butane are also known as LPG.
