LPG
Characteristics
The requirements for LPG are set out in the Minister of Energy’s Regulation on Quality Requirements for Liquefied Petroleum Gas (LPG) of April 14th 2016 (Dz.U. of 2016, item 540). The obligation to test the quality of both traditional fuels and LPG is provided for in the Act on Fuel Quality Monitoring and Control System (Dz.U. of 2006, No. 169, item 1200). This is understandable – poorly purified LPG may contain a number of components affecting the distribution infrastructure, fuel supply systems and vehicle engines. They may also have a direct environmental impact. The elements that must be removed from LPG during the production process include:
- water
- heavy hydrocarbons (oils)
- unsaturated hydrocarbons – dienes
- sulfur and sulfur compounds
Water is a major corrosive agent. In winter it causes the freezing of valves and other distribution system components. Because water is heavier, it can be effectively removed from gas during storage using drain valves.
Heavy hydrocarbons (oils) have a much higher boiling point than gas and they accumulate as deposits in the unit’s components during operation.
Particular attention is paid to removing dienes, hydrocarbons containing two double bonds in the molecule, given their proven carcinogenicity.
Sulfur compounds pollute the environment and may contaminate gas system components and cause corrosion.
LPG is drawn as liquid from the bottom of the tank and, consequently, all these factors may adversely affect the efficiency of the power supply system and the engine itself.
This is why LPG quality is a priority for us:
- we purchase gas and components only from the best and proven suppliers
- we collaborate only with accredited research laboratories
The highest quality of our LPG is confirmed for each batch by a certificate of compliance with the legal requirements applicable in Poland as set out in the Minister of Energy’s Regulation on quality requirements for liquefied petroleum gas (LPG) of April 14th 2016 (Dz.U. of 2016, item 540).
Applications
LPG is a universal fuel offering a number of benefits. It is a perfect fuel for domestic and industrial applications, it proves its worth outdoors and as a source of power for vehicles.
Fuel economy
- propane-butane is both inexpensive and highly calorific
- engines of LPG fuelled vehicles have a long lifespan and are more economical
Convenience
- well-developed distribution network allows motorists to buy gas in every part of Poland and abroad
- LPG powered vehicles are quieter and therefore more enjoyable to drive
Environmental protection
- LPG is an environmentally-friendly energy source and its combustion does not cause air pollution
- LPG contributes to the greenhouse effect to a much lesser extent than other fuels
