Liquid vs Vapour LPG

LPG exists in two different forms, liquid and gas (vapour). 

The pressure and temperature at which it is stored determines which kind you have.

Same but Different

Propane molecule modelIn Australia, LPG is Propane.  
Propane is the gas that is supplied to virtually all homes and most businesses that purchase LPG in Australia. 

Propane is a flammable hydrocarbon gas with 3 carbon and 8 hydrogen atoms in a propane molecule.

The chemical formula for propane is C3H8(Propane molecule model shown)

LPG liquid and vapour characteristics have some similarities to water and steam. 

Liquid LPG is colder, denser and heavier. 

LPG vapour is warmer and much lighter.

Liquid LPG and vapour LPG both have applications but are not interchangeable when used.  

The choice depends on the purpose. 

In most applications, such as home appliances, LPG is used as vapour (gas). 

However, some LPG fuelled products require it to be in its liquid form, such as with autogas LPG liquid injection systems.

Different Cylinders

45kg vapour cylindersLPG is liquid in a cylinder with an area at the top of the cylinder where it turns into vapour. 

However, the cylinders come in two configurations, Liquid Withdrawal and Vapour Withdrawal

The difference depends on from where the LPG is extracted. 

If drawn from the bottom of the cylinder, it comes out as liquid. 

If drawn from the top of the cylinder, it exits as vapour.

The cylinders are clearly marked as either “Vapour Withdrawal” or “Liquid Withdrawal”. 

In Australia, liquid withdrawal cylinders are also painted with a Blue top, to make them instantly recognisable. 

Using the wrong type of cylinder for an application could pose a serious safety hazard.

LPG as a Liquid

Water boils at 100°C, becoming a gas (steam).  In contrast, LPG boils at -42°C becoming gas vapour. 

It stays liquid because it is under pressure in a gas cylinder. 

As a liquid, it looks a lot like water. 

It is colourless and odourless in its natural state. 

Unlike water, 1 kilogram of LPG does NOT equal 1 litre of liquid LPG. LPG density or specific gravity is about half that of water, at 0.51. 

In Australia, where LPG is propane, 1kg of LPG has a volume of 1.96L. 

Conversely, 1L of LPG weighs 0.51kg.

The distinctive smell of LPG comes from an odorant that is added to LPG, for safety and leak detection reasons. 

Caution should always be used to avoid direct exposure, as liquid LPG is cold enough to cause severe cold burns on exposed skin.

LPG as a Vapour

Gaseous expansion of LPGLPG becomes vapour at temperatures of -42°C and above.  

LPG expands to 270 times the volume when it goes from liquid to gas.

So, 1L of liquid LPG equals 270L of gaseous LPG.  

As there are 1000L in a cubic meter (M3), 1L of liquid LPG expands to 0.27M3.

The lower and upper limits of flammability are the percentages of LPG that must be present in an LPG/air mixture. 

This means that between 2.15% and 9.6% of the total LPG/air mixture must be LPG in order for it to be combustible.

LPG gas vapour is heavier than air and will sink to and collect at the lowest point. 

If LPG is vented to the outside air, it will quickly dissipate with the slightest movement of air.  

Conversely, if LPG is vented into a sealed structure, with no air movement, the LPG gas will collect on the floor and rise vertically as more LPG is vented into the structure. 

Obviously, this would create an extremely hazardous situation.

Know the Difference for Safety

As previously mentioned, most LPG applications use vapour. 

Appliances such as water heaters, room heaters and cookers all use vapour. 

If these appliances were to have liquid LPG flow to their burners, the result could possibly be a fire or similar safety hazard. 

This is why you must use the right type of cylinders and LPG cylinders should always be kept upright, so that only vapour is released. 

An upside-down vapour cylinder, or even one laying on its side, could release the LPG as a liquid.
