LPG Vaporisation - How Does LPG - Propane Turn from Liquid to Gas?

LPG vaporisation is the process through which liquid LPG turns into gaseous LPG. The LPG liquid boils at -42°C or -44°F, by drawing heat from the walls of the cylinder, and turns into gas. LPG vaporisation happens when some of the cylinder pressure is relieved by turning on an appliance.

Can Propane-LPG Tanks (Gas Cylinders) Explode - Propane-LPG Gas Tank Explosion - LPG Explosion

A gas cylinder can explode if it heats up and the pressure builds at a rate that overcomes the pressure relief valve. The result could be a BLEVE - Boiling Liquid Expanding Vapour Explosion – a gas cylinder explosion, which is a rare event.

However, that is a very unlikely and uncommon scenario. Propane-LPG gas tank explosions (gas cylinder explosions) do not happen with any frequency. An Propane-LPG gas tank explosion is actually quite rare. Propane tanks-LPG gas cylinders can explode but not easily or often. Even trying to cause a Propane-LPG gas tank explosion intentionally is very challenging.

Now, you may be thinking that I am only saying this because I work for an LPG company.

How can what I say be true when you see reports of “Propane-LPG tank explosion” in the news with some frequency?

The issue lies with the erroneous reporting of the LPG explosion facts…

What is the Percentage of Propane and Butane in LPG Gas Mixture - Which Gas is Present in LPG

Liquefied petroleum gas (LPG or LP gas) is also referred to by its constituent names - propane or butane. LPG are hydrocarbon fuel gases used for heating, cooking, hot water and vehicles.

Most countries have either 100% propane (Australia & USA), an LPG gas mixture of 60:40 propane:butane (NZ & Belgium) or percentage of propane and butane in LPG around 35:65 propane:butane LPG gas mixture (India, Spain & Hungary).

LPG Gas Mixture - Liquefied Petroleum Gas Mixture

A liquefied petroleum gas mixture (LPG gas mixture) consists of flammable hydrocarbon gases that include propane, butane, isobutane and LPG gas mixtures of the three gases. The percentage of propane and butane in an LPG gas mixture ranges from 100% propane to 20% propane and 80% butane.

Is LPG-Propane Toxic? Can Propane Fumes Kill You? LPG Gas Leak Effects

LPG (Propane) is a colourless, odourless, non-toxic gas and is also referred to as natural gas liquids – NGL.

It is flammable, so it needs to be treated with respect.

However, overall LPG has an excellent safety record.

LPG Gas Manufacturing Process: Where Do We Get LPG Gas From - How is LPG Gas Made

LPG is produced during the crude oil refining or separated during natural gas production. LPG is gaseous if released. After production, LPG gas is liquefied through a pressurization process, for ease of storage and transport in gas cylinders or bulk tanks.

The gases produced in the LPG production process are mainly propane and butane, with small fractions of other NGL gases.

POL Gas Fittings, POL Fitting, POL Valves Fittings, Cylinders & Gas Regulators

A POL gas fitting (POL fitting) is found on POL cylinders, POL valves, POL gas regulators and various POL connection fittings including hoses and adaptors. POL valve fittings are found on gas bottles ranging from small BBQ bottles to large commercial gas bottles.

Butane vs Propane vs Isobutane - What is Butane?

Liquefied Petroleum Gas

Propane has a lower boiling point than butane at -42°C vs -0.4°C. Propane also has about 4x the vapour pressure of butane. This makes propane a better choice for cold climates whilst butane is a better choice for propellant use.

The big differences between butane vs propane are in the usable temperature range and the vapour pressure inside of the gas bottle. Propane can be used instead of butane in all fuel applications. Butane does not work as a fuel in a below freezing climate but butane is generally a better propellant, versus propane, due to its lower vapour pressure.

In other ways butane and propane are almost or exactly the same, such as energy content and many of their applications.

Discover the real difference between butane vs propane vs isobutane vs LPG. All three gases are consider to be LPG - Liquefied Petroleum Gas.

How Does a Gas Water Heater Work? (How Instant Gas Geyser Works)

Tankless continuous flow through hot water heater systems are the most popular type of gas hot water heater. 

The reasons are simple -- they never run out of hot water and they are energy efficient. 

But how does a flow through hot water heater work (how instant gas geyser works)?

Converting LPG & Natural Gas Appliances

LPG to Natural Gas Conversion Kit - Natural Gas to LPG Conversion Kit

LPG (propane) and natural gas (methane) appliances are not interchangeable — they must be converted and this takes an LPG to natural gas conversion kit or vice versa.

As a result of a move, you may have an appliance that you need to convert from natural gas to LPG or from LPG to natural gas.

Can this be done and what is involved?
