Characteristics of LPG

The significant characteristics of LPG are:

  • LPG allows efficient cooking: LPG is easily controllable so it helps consumers to cook with desired heat or flame intensity.
  • Density: LPG at atmospheric temperature and pressure is a gas which is 1.5 to 2.0 times heavier than air. It is readily liquefied under moderate pressure. The density of liquid is approximately half of water and ranges from 0.525 to 0.580 @ 15 deg C.
  • LPG is heavier than air: When LPG leaks from the cylinder, the vapor will flow and accumulate at the ground level. Therefore, leaks are dangerous as LPG can burn when it comes in contact with any source of ignition.
  • LPG is odourless and colourless: To detect leakage, LPG is given its distinctive smell by adding a special stenching agent that will ensure it can be detected even if the leakage is well below the level of flammability.
  • LPG is portable: LPG can be transported, stored, and used virtually anywhere. Although LPG is stored as a liquid, it is generally used as a vapor. One unit of liquid LPG will generate 270 units of LPG vapor or gas.
  • Explosive limit:  LPG has an explosive range from 2.1% to 9.5% volume of gas in air. This is considerable narrower than other common gaseous fuels.
  • Auto Ignition: Auto ignition of LPG is around 410 to 580 deg Centigrade hence it will not ignite on its own at normal temperature.
