Liquefied Petroleum Gas (LPG) the logical choice for off-mains gas businesses

LPG is not new; it’s been in use nearly as long as refined oil has. However, for businesses that are concerned about CO2 and other harmful emissions, it’s the most logical energy choice for modern businesses operating off the mains gas grid. Indeed, it is also the most logical fossil fuel to partner with renewable technologies for businesses that are intent on integrating renewable technologies into their energy mix.

In addition, LPG is often cheaper that oil on a pence per kilowatt basis. Check out our Low Price Guarantee for business owners if you don’t believe us.

Two varieties of LPG

LPG is a member of the family of hydrocarbon gases which comprise hydrogen and carbon atoms and it is sold in two popular forms:

  • Propane-which is used for heating and many other commercial applications. It is stored in bulk tanks or red cylinders
  • Butane-which is used primarily for mobile indoor heaters and is stored in Blue cylinders

Where does it come from?

  • It’s a by-product of the process of separating petrol from crude oil
  • It can also be found in its natural state under the sea or ground
  • More recently, it can be extracted from Fracking wells

There appears to be an abundant supply of LPG from fields across the globe, so much so that the World LPG association predicts that supply is expected to exceed demand in the near future.

Difference between LPG and Natural Gas

The two characteristics that distinguish LPG from Natural Gas are:

  • Under modest pressure LPG gas vapour turns into a liquid
  • This makes it easy to transport and store in cylinders or vessels…perfect for off-mains gas locations
Clean combustion

In order to burn, LPG requires oxygen (c.21% in ambient air) plus a source of ignition. When burnt efficiently it releases: Heat and harmless carbon dioxide (CO2) and water vapour

Compact energy

LPG is stored as a liquid when under pressure. At 15 degrees Centigrade the pressure in a cylinder / tank is:

  • Butane: 20-25 psi or 1.4-1.7 bar
  • Propane: 100 psi or 6.9 bar

A small amount of LPG will expand over 200 times when vaporised:

  • 1 volume of Butane = 233 volumes of butane gas
  • 1 volume of Propane = 274 volumes of Propane gas
Performs in any weather

Propane boils at very low temperatures, turning into a gas at: -42 Centigrade so performs in the most extreme temperature conditions. Butane boils at -2 Centigrade which is why it is reserves for indoor heaters.

Colourmore and odourless fuel

It does not omit a pervasive smell like oil but a stenching agent is added during production to aid detection.

Pollution-free in its pre-burnt state

LPG vapour/gas is heavier than air so escaped liquid / gas will fall to the ground before harmlessly evaporating. It also lighter than water, therefore escaped LPG will simply float on water before evaporating. It’s also carbon-neural in its liquid or gaseous forms. It only omits CO2 when burnt.
