What is the Difference between LNG and LPG in the Container?

Ø As previously explained, natural gas is methane whilst LPG is either propane, butane, isobutane or a mixture of the three.

Ø So, whilst LPG is liquefied using relatively low pressures at ambient temperatures, LNG is liquefied cryogenically - chilling it to −161°C - at close to atmospheric pressure.

Ø Another major difference is that LPG can typically be used right from the cylinder .

Ø LNG requires regasification, to get it to revert to its gaseous state and can then used as typical natural gas.

Which is Safer, LPG or LNG?

· Both LPG and LNG are flammable hydrocarbon fuels.

· Under the right circumstances either one could burn or explode.

· LNG is more dangerous for the environment, as methane is a very strong greenhouse gas - even worse than CO₂.

· LPG (propane and/or butane) are not greenhouse gases.

What is LPG?

LPG is the acronym for Liquefied Petroleum Gas 

Ø LPG is used for heating our homes & hot water, cooking our food, powering our BBQs & fuel our cars.

Ø It also powers many business and agricultural processes.

How Does LPG Work?

Ø LPG is stored under pressure, as a liquid, in a gas bottle.  

Ø It turns back into gas vapour when you release some of the pressure in the gas bottle by turning on your appliance.

Ø Almost all of the uses for LPG involve the use of the gas vapour, not the liquefied gas. 

What is LPG made of: LPG Composition

The gases that fall under the “LPG” label, including Propane, Butane and Isobutane, as well as mixtures of these gases. 

The two most common are Propane and Butane.

Where does LPG come from?

· LPG is not made or manufactured, it is found naturally in combination with other hydrocarbons.

· LPG is produced during natural gas processing and petroleum refining. 

· Once refined, LPG is stored as a liquid under pressure in gas bottles or tanks.

· LPG processing involves the separation and collection of the gas from its petroleum base.

· About 60% is produced from the natural gas stream that comes out of the wellhead.

· The other 40% is produced during the crude oil refining process.

· LPG is isolated from the hydrocarbon mixtures by its separation from natural gas or by the refining of crude oil.

· Natural gas liquids (NGL) range from 1% to 10% of the natural gas flow.

· Similarly, LPG produced from crude oil refining constitutes between 1% and 4% of the crude oil processed.

· Both processes begin by drilling oil wells.

· Following its refinement, LPG is stored and distributed as a liquid under pressure until used, at which point it is utilised as either a liquid or a gas (vapour).

Refined from Oil & Natural Gas

· LPG processing involves separation and collection of the gas from its petroleum base. 

· LPG is isolated from the petrochemical mixtures by separation from natural gas or by the refining of crude oil.

· Both processes begin by drilling oil wells. 

· The gas/oil mixture is piped out of the well and into a gas trap, which separates the stream into crude oil and "wet" gas, which contains LPG and natural gas.

· The heavier crude oil sinks to the bottom of the trap and is then pumped into an oil storage tank for refining. 

· Crude oil undergoes a variety of refining processes, including catalytic cracking, crude distillation, and others.  

· One of the refined products is LPG.

· The "wet" gas, off the top of the gas trap, is processed to separate the gasoline (petrol) from the natural gas and LPG. 

· The natural gas, which is mostly methane, is piped to towns and cities for distribution by gas utility companies. 

· The petrol is shipped to service stations.

· The LPG also enters the distribution network, where it eventually finds its way to end users, including Home LPG and Commercial LPG users all around Australia and the world.
