Mystery of the Secret Stench

For most of us, the scent of something rotting is simply repulsive.

But for others, such as carrion-feeding vultures, hyenas and house flies, it’s a scent that means meal time!

One evening, having arrived home from a long and tiring day at the office, I was greeted at my front door by a strong but unfamiliar odour. I couldn’t quite put my finger on it…

What is Bottled Gas?

“Bottled gas” is typically a synonym for “LPG” or “propane”.

Whilst there are actually many types of gas that come in bottles or cylinders, including industrial and welding gases, the term is generally understood to refer to LPG – propane.

In some countries, bottled gas can also refer to butane or propane/butane mixtures of gas.

Is LPG (Propane) a Fossil Fuel?

Is LPG (Propane) a Renewable Energy Source?

"Yes"… LPG is a low-carbon fossil fuel.

LPG comes from drilling oil and gas wells.

It is a fossil fuel that does not occur in isolation.

LPG is found naturally in combination with other hydrocarbons, typically crude oil and natural gas.

How an LPG - Propane Cylinder Works

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

LPG gases can all be compressed into liquid at relatively low pressures.

LPG liquid boils and turns back into gas vapour when you release some of the pressure in the gas bottle by turning on your gas appliance.

Can LPG be Used in CNG Cars?

CNG is compressed natural gas – methane.

LPG is liquefied petroleum gas – propane.

There are many similarities between LPG and CNG, as well as some major differences.

Is LPG-Propane Heavier than Air? Lighter than Air?

LPG gas is not lighter than air.

LPG (propane) is heavier than air.

Butane is also heavier than air.

In fact, LPG is over 50% heavier than air at sea level (1 atm).

As a result, LPG gas will settle in low places.

How Much Pressure in LPG Cylinder (Propane) & in Which State is it?

One of the most common questions we hear is "How much pressure in LPG cylinder?"

So, how much LPG cylinder pressure do you have and how much do you need?

First, some background regarding how much pressure in LPG cylinder:

•  The pressure inside of an LPG cylinder, or larger vessel, is dependent upon the temperature of the vessel.

•  The higher the temperature, the higher the pressure of the LPG within the cylinder.

•  The pressure of LPG (propane) goes from 0 kPa (0 PSIG or 0 bar) at -43ºC to 2482 kPa (360 PSIG or 24.8 bar) at 70ºC.

•  The LPG – propane – exists as both liquid and vapour (gas) within the cylinder.

•  The term “pressure” refers to the average force per unit of area that the gas exerts on the inside walls of the cylinder.

What Does LPG Stand For? - Meaning of LPG

What Does LPG Stand For?  Liquefied Petroleum GasLPG (or LP Gas) stands for the acronym for Liquefied Petroleum Gas or Liquid Petroleum Gas, which is made up of the hydrocarbons propane, butane and isobutane.

Liquefied Petroleum Gas is a low carbon fuel used for heating, cooking, various industrial and agricultural applications and as vehicle fuel.

LPG is produced during natural gas processing and petroleum refining.

Liquefied Petroleum Gas is the preferred term within the industry, as it signifies the need to take action for the gas to become a liquid.

But there are also many other terms...
