What is LPG Gas? 18 LPG Gas Fast Facts
LPG gas is used as a fuel for many residential, commercial and agricultural heat applications, including cooking. It is also employed as a propellant, refrigerant, vehicle fuel and petrochemical feedstock.
LPG gas – Liquefied Petroleum Gas – describes flammable hydrocarbon gases including propane, butane, isobutane and mixtures of these gases commonly used as heating, cooking, hot water and auto fuel. LPG gas is also used as propellant, refrigerant, and petrochemical feedstock.
LPG gas is a fossil fuel that does not occur in isolation. LPG gas, liquefied through pressurisation and stored in gas cylinders, comes from natural gas processing and oil refining.
LPG gas is separated from unprocessed natural gas using refrigeration. LPG gas is extracted from heated crude oil using a distillation tower and is also referred to as natural gas liquids – NGL.
LPG is generally stored, as a liquid, in steel vessels ranging from small BBQ gas bottles to larger gas cylinders and LPG storage tanks.
Other gases that also fall under the “LPG gas” label, include ethane, ethylene, propylene, butylene and isobutylene, as well as mixtures of these gases.
In different countries, what is supplied as LPG gas can be propane, butane or propane-butane blends.
LPG gas is just propane, in Australia.

18 LPG Gas Fast Facts
1. LPG (or LP Gas) is the acronym for Liquefied Petroleum Gas or Liquid Petroleum Gas.
2. LPG gas is a group of flammable hydrocarbon gases that are liquefied through pressurisation and commonly used as fuel.
3. LPG gas comes from natural gas processing and petroleum refining.
4. There are a number of gases that fall under the “LPG gas” 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 gas is frequently used for fuel in heating, cooking, hot water and vehicles, as well as for refrigerants, aerosol propellants and petrochemical feedstock.
7. LPG gas is generally stored, as a liquid, in steel vessels ranging from small BBQ LPG gas bottles to larger LPG gas cylinders and bulk storage tanks. (45kg LPG gas bottles shown)
8. Colourless, heavier than air and odourless until odorant is added for safety reasons.
9. When lightly compressed it becomes a liquid. 1 litre of liquid LPG gas (propane) is the equivalent of 270 litres of gas.
10. LPG gas burns readily in air and has a high-energy content making it an excellent fuel for heating, cooking and automotive use.
11. LPG gas heating gases have a higher calorific value versus natural gas.
12. LPG gas can range from virtually 100% propane to 100% butane.
14. LPG gas measurement is done in weight, liquid volume, gaseous volume, energy content and pressure.
15. LPG gas exists in two different forms, LPG liquid & vapour (gas). The storage pressure & temperature determines which kind you have
16. The more technically correct term for LPG gas in its gaseous state is LPG vapour, not gas. Vapours are gases, however, not all gases are vapours.
17. The chemical formulas for propane - C3H8 - and butane - C4H10 - are different. However, the formula for butane and isobutane are the same. Isobutane (i-butane) is an isomer of butane, so it has a different arrangement of its atoms.
18. Autogas is typically an LPG gas mixture of propane and butane but can be all propane, too.

How is LPG Gas Made? What is the Production Process?
LPG gas is made during natural gas processing and oil refining.
LPG gas is separated from the unprocessed natural gas using refrigeration.
It is extracted from heated crude oil using a distillation tower.
The LPG gas then pressurised and stored as a liquid in cylinders and tanks.
How is Cooking Gas Produced
Cooking gas is produced exactly the same way LPG (propane) is made, from a manufacturing production process that occurs during natural gas processing and oil refining. That's because cooking gas is LPG (propane) and not some different gas.
Cooking gas can also be produced using natural gas or piped gas.
Gas Bottles - LPG Gas Bottles for Home
Gas bottles range from small portable cylinders to large tanks and bulk storage vessels. LPG gas bottles are typically steel vessels for storing the common LPG gases, propane or butane. Homes and small businesses typically use either a 45kg gas bottle, 90 kg gas bottle or the larger 210kg LPG gas bottle sizes (gas cylinder sizes) and cylinder capacity.
High volume users have the larger LPG gas tank sizes (LPG tank sizes).
BBQ gas bottle sizes come in 4kg & 9kg gas bottle dimensions, cylinder capacity & gas bottle sizes (propane gas bottle sizes). Small LPG gas bottles are portable, as used in camping.
What is LPG Gas Used For?
LPG gas has hundreds, if not thousands, of uses.
The LPG gas uses most people can name are around the home, in their cars or for their business.
Business and industry use LPG gas for a multitude of processes including steam boilers, kilns, ovens and LPG gas forklifts.
Transport is also a big user of LPG gas (Autogas), either as propane or propane mixed with butane, to power various vehicle types.
There are also many, many more LPG gas applications, including power generation and the hospitality industry.
LPG Gas Heating Gases
Most LPG gas uses involve the use of LPG heating gases.
The LPG gases would be either propane, butane or a mixture of the two, depending on where you live and possibly the season, as well.
Cooking, space heating and hot water are the most common uses for LPG gas heating gases.
There are also many industrial and agricultural application that requires heat, too.
Many of these involve boilers, powered by LPG gas heating gases.
