Propane gas, which is also called liquefied petroleum gases(LPG), is available everywhere.propane is primarily act as a fuel source. Propane heat our homes & gives us hot water, cooks our food, power our fast foods and fuel our vehicles .
Propane is also used by business and agricultural all sorts of purposes.

Propane gas introduction

Propane gas is a gas which fits the definition of LPG(Liquefied Petroleum Gas).it is a flammable hydrocarbon gas that is liquefied through pressurization and mostly used for fuel in heating,cooking,make hot water and car oils.Propane use for refrigerants, aerosol propellants and petrochemical feedstock.

Propane gas can be shrunk into liquid at relatively low pressure.Propane is stored, as a liquid,in steel vessels ranging from small BBQ gas bottles to larger gas cylinders and LPG  tanks.

Propane comes from  processing of natural gas and refining petroleum.

There are a number of other gases which fall under LPG label, including butane and iso – butane , as well as mixtures of these gases and are also referred to as natural gas liquids(NGL).

Where Does Propane Come From?

Propane gas is a transportable gas that comes in a cylinder that comes from natural gas wells and oil wells.

Propane is a fossil fuel which is not occur in isolation.Propane is naturally combination with another hydrocarbons.

Propane gas which comes from natural gas processing and oil refinery processes. It is isolated, liquefied through pressurization and stored in pressure vessels for easy storage and distribution.

How is Propane Made?

Propane is made when natural gas and oil refining processing.It is separated from the unprocessed natural gas.

Propane gas is extracted from heated crude oil by using a distillation tower.

It is then pressurization and stored as a liquid in cylinders .

 Propane Made from Natural Gas

Propane gas don’t made from natural gas since it is separated from natural gas.

It is necessary think what is “raw natural gas”? as it leaves the gas, sustains other gases (including propane) and impurities that need to be processed out to obtain the nearly pure methane gas that we refer to as “refined natural gas”.

Propane gas is separated from the raw natural gas, the propane from the raw natural gas stream.

 Uses  and Purposes of propane gas

Hospitality industry, hotels,restaurants,etc use propane for heating,cooking .in chicken farm use  propane to keep the chicks warm. A farmer uses of propane include flame weeding and irrigation pumps. Auto body repair shops use propane for the oven for painted cars. Refrigeration manufacturers company use propane for a refrigerant gas.Many companies use propane to fuel boilers for multiple purposes.So list for using purposes of propane just goes on and on.

Common Uses of Propane gas

Propane gas is used for thousands of uses. Besides,propane is used for propellant vehicle fuel and petrochemical feedstock.

The propane uses most people can name are around their house , or for their business or their vehicles .

Propane use in leisure time activities including caravans, boats, recreational vehicles.

Propane use for fuel for many commercial and agricultural heat applications also.

Business and industry use propane for a multiple processes including steam boilers, kilns fork lifters etc.

heating greenhouses, heat water for dairies, irrigation pumps and heating animal enclosures are just some of the agricultural uses for propane.

Transport is also a big user of propane, either alone or mixed with butane, to power various  types of vehicles.

Propane gas are also more and more uses, including power generation and the eligible commercial system .

Propane gas used as a fuel

Propane is used as a fuel because of its portability as well as energy density.Besides, it only requires a pressure for liquefication maintaining a practical vessel weight.So, propane gas is used as a fuel transport and in areas without natural gas.

Propane identified by Many Names

In Australia, propane has identified by many names.

It is also known to LPG, LPG Gas, LP Gas, BBQ Gas or Auto Gas.

In the the country of USA it is just known Propane.

In the UK, it is known to as either propane or LPG.

Propane gas works as

Propane is stored as a liquid, in a gas loaded bottle.

It turns back into gas vapour when you release some of the pressure.

Almost all the uses for propane involve the use of the gas vapour.

Propane Made of,Composition and Structure

Propane composition is as one type of hydrocarbon gas with 3 carbon and 8 hydrogen atoms in a propane molecule.The formula for propane is C3H8.

Propane gas heating system sub – types for sale include radiant,radiant- convectors, flued radiant, freestanding fireplaces, fireplace inserts, inbuilt fireplace gas heaters and power flued gas heaters .

A wide range of propane gas heating appliances systems to choose from,there is a model that is just right.

Propane Tank

Propane tanks are basically steel vessels for storing the common LPG gases, propane. House and small businesses basically use either 45kg gas bottles or the big 90kg or 210kg LPG gas bottle.BBQ propane tanks in 9kg and 4kg gas bottle.big volume users have the larger sizes tank.

Propane tanks can be called “Propane Gas Bottles”, “LPG Bottle”, “LPG Gas Cylinders” or just “Gas Bottle”.

Propane gas tanks apprehends liquid and gas, as propane liquefies under relatively low pressure.A small propane gas bottle is portable which used in camping.

A propane tank is considered a quantity low pressure versus high pressure cylinders, which is mainly used with CNG.

Propane tank sizes and volumes are vary, based on use and demand.

Can we Bury a Propane Tank?

Yes, you can bury a propane tank which is made for burying. A buried propane tank needs anti – corrosive coatings and. Underground propane tanks are filled by hose.

The burying of a propane tank must be handled by an experienced company and minimum and maximum distances from your home or business apply.The buried propane tank must safe away from any ignition source.

Residential propane tank regulations

Residential propane tank regulations and propane tank distance requirements are important for a good installation.The installation distance requirements can vary based on the size of the tank.The standard minimum distance is 10 feet or 3 meters, including ignition sources openings in all directions.

Propane Gas Pressure Regulations

A propane regulator is used to control the pressure of the propane gas delivered to the appliance, from the gas an automatic manner the Propane gas pressure regulators modulate high pressure gas down to the maximum limit.

The gas bottle pressure can be 800-900kPa which is regulated down to the 2.75kPa.

Propane gas pressure regulators for LPG bottles are usually factory reset to the standard 2.75kPa standard operating pressure for the users.

Are propane exclusive? How a propane gas cylinder explore?

Propane cylinder or propane LPG tank explosions can not occur any frequency. A propane LPG tank explosion is actually rare. Gas cylinders can be explosive but not easily. Even trying to create a propane cylinder explosion intentionally challenging matter.

Propane is explosive under the accurate environment .The propane can be explosive if it is in limits of flammability, between 2.15% and 9.6% percent of the total propane and air mixture.

Properties of Propane?

Propane Boiling Point

Water boils at 100°C, becoming a steam gas .

propane boils at -42°C becoming gas vapour.

in under pressure in a gas cylinder, Propane stays liquid .

it looks a lot like water, As a liquid

in its natural state,It is colourless and odourless

Odourless is Added for Safety

propane is an odourless gas in its natural state,

The distinguishable smell when people associate with propane gas is actually added to it as a safety measure.

Avoid Direct Contact (Cold Burns)

Caution should be used to avoid direct exposure, as liquid propane is cold sufficient to cause severe cold burns.

Specific Gravity of Propane(Density)

1 kg of propane does NOT equal 1 litre of propane.

The density of Propane is about half of water near 0.51.

One kg of propane has a volume of 1.96L.

1L of propane weights 0.51kg.

1lb of propane @60ºF has a volume of 0.24 US gallons.

1 US gallon of propane (@60ºF) only weights 4.23lbs,instead of the 8.34lbs it would weight of water.

Propane Gaseous Expansion

Propane expands to 270 times the volume.

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

As there are 1000L in a M3, 1Litre of liquid propane expands to 0.27M3 cubic meter. 

1 US gallon of liquid propane equals 36.38ftof gaseous propane.

Energy Content of Propane

This also converts to 6.9kWh.

Propane contains  25MJ per litre.

More propane energy content facts:

1 gallon propane (US) = 91,502 BTU @ 60ºF

1 therm = 100,000 BTU

1ft3 propane = 2,488 BTU of Gas @ 60ºF

1 US gallon propane = 1.1 thrm

1 watt = 3.41214 BTU/h

Combustion Formula

In the presence of sufficient oxygen, propane burns to form water vapour and carbon dioxide, as well as sufficient heat.

Propane+ Oxygen(O2)→ Carbon Dioxide(Co2) + Water + sufficient Heat

(C3H8 + 5O2 → 3CO2 + 4 H2O + Heat)

If not sufficient oxygen is present for complete combustion,incomplete combustion occurs with water, CO(Carbon monoxide), and carbon dioxide being maked.

Propane Flame Temperature

 propane flame burns at 1980ºC (3596ºF).

When propane gas burns properly, the flame is blue.

A yellow or red flame is usually used as incomplete combustion.

Limits of Flammability

The propane flammability limits are the percentages of propane that must be present in an propane mixture.

Thar means in between 2.15% and 9.6% of the total propane mixture must be it to be combustible.

Propane Flash Point

The flash point of propane is the minimum temperature at which propane will burn on its own after ignited on.

However, it will burn below -104°C when a source of continuous ignition is present.


Propane gas is heavier than air and and collect at the lowest point.

it will quickly dissipate with the slightest Movement, If propane is vented to the outside air.

Conversely,the propane gas will collect on the floor and rise vertically as more propane is vented into the structure, if propane is vented into a sealed structure.
