Liquefied Petroleum Gas (LPG) is a clean and efficient source of energy, which consumers all over the world have easy access to. LPG is a by-product of natural gas and petroleum production; its unique properties mean that it constitutes a universal source of energy and finds extensive usage in the economy. It is used in the following fields:



LPG properties


In accordance with the Polish PN-82/C-96000 standard liquid hydrocarbon gasses (C3 - C4) are liquefied and remain so under pressure of their own fumes mixtures of aliphatic hydrocarbons, with primary components described by the present standard by the capital letter C and a numerical index include:

and in smaller quantities:


Depending on the content of basic hydrocarbons and the designated use, hydrocarbon gasses (liquefied C3 - C4) are classified into three types of mixtures: technical butane (mixture A), technical propane butane (mixture B) and technical propane (mixture C).

LPG Stations

Main LPG advantages:


There are two methods for obtaining LPG

  - from boreholes in the ground,

  - petroleum processing in refineries.

LPG supply is not dependent on a single source


Contrary to a disruption-prone permanent network, LPG may be transported from anywhere using optimal land and sea connections.


LPG with its flexible infrastructure and small environmental impact, naturally complements the renewable energy system and compensates the interruptions in its operation.

LPG combustion generates less pollutants than combustion of heating oil, diesel, wood or coal. Emission of benzene and polycyclic aromatic hydrocarbons is also reduced. Carbon dioxide emission is 20% less than for combustion eating oil and 50% less than for coal.
