LPG: frequently asked questions

LPG (Liquefied Petroleum Gas) is a mixture of hydrocarbons, mainly composed of propane and butane.

LPG is an extremely versatile energy source: it can be used to heat and cool rooms, cook food, supply industrial equipment, etc.

Its high calorific value allows large amounts of energy to be available for limited quantities of product.

It has a low environmental impact and thanks to the possibility of compressing it in a liquid state it can be stored in small spaces and easily transported anywhere, even places not reached by the methane network.

LPG is sold under the names of commercial propane (mixture C, according to UN shipping regulations), commercial mixture (mixtures A1, B1, B2, B) and commercial butane (mixtures A, A01, A02, A0).

Commercial propane may be accompanied by propylene, butylene, butane and ethylene with a propane content in excess of 90%.

The commercial mixture is a total mixture of hydrocarbons obtained from the combination of approximately 70% n-butane and isobutane and an average of 30 % propane.

Yes. Islands, mountain regions and areas non reached by the methane network benefit from a reduced excise duty for LPG for heating purposes. In order to be entitled to this, the tank must be installed in an area identified by the municipal administration by special resolution.

Yes. A tax concession is granted for the industrial use of LPG. In order to qualify, the installation must meet certain technical requirements or the activity must be classified as “outside the scope of excise duties”.

Yes. LPG has a lower price per calorific value than most fossil fuels.

The price of LPG for transport use is not comparable to that for residential use because it is subject to a different excise duty rate and has a simplified distribution and logistics system (volumes transported, storage size, plants location).

Yes. LPG, together with natural gas, is the cleanest fossil fuel, with low emissions of CO2, unburnt hydrocarbons, sulphur dioxide and nitrogen oxides. In particular, during the combustion of LPG, no particulate matter and fine dust (PM10 and PM2.5) typical of the combustion of biomass, diesel and fuel oil are produced.
