Is There a Difference Between Propane vs LPG? Is Propane the Same as LPG
Many of the gas appliances sold in Australia are manufactured overseas and call for propane vs LPG. So, you get it home, open the box, and it says that the appliance is made for use with propane vs LPG. Is propane the same as LPG?
Propane vs LPG or is it LPG vs Propane (LP vs Propane)
Propane is LPG but not all LPG (LP) is propane.
LPG – Liquefied Petroleum Gas – is flammable hydrocarbon gas liquefied through pressurisation.
Propane is classified as LPG (LP), along with butane, isobutane and mixtures of these gases.
LPG comes from natural gas processing and oil refining.
LPG is frequently used for fuel in heating, cooking, hot water and vehicles.
The Name Game - Is Propane the Same as LPG
Propane is the same as LPG but LPG can include other gases, as well. In addition to propane, LPG can be butane, isobutane or any of a number of different gases.
7 Important LPG Facts for LPG vs Propane
1. LPG is the acronym for Liquefied Petroleum Gas or Liquid Petroleum Gas.
2. LPG (LP) is a group of flammable hydrocarbon gases, including propane, that are liquefied through pressurisation and commonly used as fuel.
3. LPG comes from natural gas processing and petroleum refining.
4. There are a number of gases that fall under the “LPG” label, including propane, butane and isobutane (i-butane), as well as mixtures of these gases.
5. LPG gases can all be compressed into liquid at relatively low pressures.
6. LPG is frequently used for fuel in heating, cooking, hot water and vehicles, as well as for refrigerants, aerosol propellants and petrochemical feedstock.
7. LPG (propane) is generally stored, as a liquid, in steel vessels ranging from small BBQ gas bottles to larger gas cylinders and storage tanks.
Propane (LPG) is Not Natural Gas
How Does LPG Work?
LPG is stored under pressure, as a liquid, in a gas bottle.
It turns back into gas vapour when you release some of the pressure in the gas bottle by turning on your gas appliance.
Almost all of the uses for LPG involve the use of the gas vapour, not the liquefied gas.
What is LPG Used For?
LPG has hundreds, if not thousands, of uses.
Business and industry use LPG for a multitude of processes including steam boilers, kilns, ovens and LPG forklifts.
There are also many, many more LPG applications, including autogas, power generation and the hospitality industry.
What is LPG made of: LPG Composition
Propane Only in LPG vs Propane
Liquid Propane Gas - LPG vs Propane Liquid
Liquid propane gas is the form propane takes when it is under pressure or under -42°C. The liquid propane sits in the bottom part of the propane gas bottle with propane gas vapour in the top part of the liquid propane gas bottle.
The liquid propane turns to gas vapour when some of the pressure is released, causing the liqud propane to boil and vaporise into gas.
Most propane applications use the gaseous propane and not the liquid propane.
And Then There is Butane
Now, if you are reading this blog from another country, LPG may not be just Propane for you.
It could be butane. (Butane molecule model shown)
Autogas is Different
