What is LPG



What is LPG?


LPG (Liquid Petroleum Gas) is a mixture of hydrocarbons, mostly propane and butane. It is extracted for more than 70% from natural gas and for the remaining from oil refining.
At room temperature, LPG passes to the liquid state when subjected to a moderate pressure: so it can be easily transported eveywhere. It is odorized to detect its presence in case of leakage.
LPG can be easily transported by all means:by Sea through ships, overland by tank trucks, by railway through rail tanks.

Thanks to its high calorific value and versatility, LPG is a unique, safe and environmentally friendly fuel.

Market and development

LPG market in Italy is one of the largest in Europe. In 2014 the total demand for the LPG in Italy has reached the quota of 3.064 million tons, whose 49.1% employed in combustion and 50.9% in the automotive sector. For 2015 it has been estimated a slight increase in demand, which is expected to reach about 3.3 million tons, with an equal distribution between heating and automotive.

In this scenario ButanGas stands as one of the leading companies in the market: ButanGas is one of the few national companies which imports directly the product, based on a widespread organization throughout the country and an experience gained in almost 70 years of activity. ButanGas adopts the highest standards of safety and quality and constantly invests in staff and technology to ensure its customers a great efficiency with full respect for the environment.

LPG Uses

LPG supplies many sectors: it is optimal for domestic use and leisure time, for handcraft and industry, as well as agriculture, livestock and automotive.

There are tax incentives for productive activities and for users who live in areas without direct access to piped natural gas. Also from an economical point of view, LPG is therefore advantageous compared to other fuels.

LPG  for civil uses

LPG is used daily for space heating, the production of hot water and the cooking, through a wide range of equipments such as boilers, heat pumps, heaters, fan coils, etc.

Less known are the new uses of LPG, which is used for the cooling of the environment and the power of heaters for swimming pools and barbecue grills, radiant mushrooms, traps for mosquitoes. In addition LPG gives energy to major appliances such as refrigerators and washer-dryers, as well as to pressure washers and current generators.

Tertiary sector

The easiness of installation and the immediate use at competitive costs, the constant efficiency, the availability of a multipurpose energy twenty-four hours a day, 365 days a year, make the LPG a profitable product for the hospitality industry, offices, shopping malls, restaurants, spas.

Sports associations

Thanks to its good cost, LGP has spread to all the facilities as football and athletics fields, gyms and the like, where it is used to heat small rooms and showers, swimming pools and covered sports fields.

Agricultural and livestock uses

LPG reaches and covers easily the large areas devoted to agriculture and animal husbandry, unlike other fuels.

Industry and handcraft

More economical and cleaner than diesel, constantly available, non-polluting, at very low management and maintenance costs if compared to fuel oil, with a steady efficiency and a higher calorific value in comparison to natural gas, LPG offers benefits that other fuels cannot match. In addition, the industrial sector benefits from tax relief that makes LPG a favourable and applicable choice in every field.

Chp, trigeneration

Thanks to the latest generation of machines introduced in the market, cogeneration and trigeneration have become a reality. The adoption of LPG to power these devices has promoted their spreading and use, even in areas not supplied with methane.

LPG for Automotive

The power supply of vehicles is one of the uses for which LPG is so well-known. In recent years, this use has gathered a new momentum, especially thanks to the recognized characteristics of good costs and ecology of LPG. Cars powered by LPG are not stuck in traffic jams and often have free access to the LTZ. The car manufactures, realizing the possibility to break down not only carbon dioxide emissions but above all unburned hydrocarbons and particulates (PM10, PM2, PM5) of LPG engines,
have finally expanded their offer introducing modern and efficient models. The new systems assembled on cars also allow their parking on the basements of covered garages.

Environmental benefits

LPG is the cleanest fuel, along with natural gas, among all fossil fuels. Gases produced by its burning have reduced emissions of:

• Carbon dioxide (CO2);

• pollutants such as carbon monoxide, unburned hydrocarbons, sulphur dioxide, nitrogen oxides, particulates or fine dust and volatile organic compounds.

In addition the LPG:

• has relatively low a carbon / hydrogen ratio;

it is not toxic;

it is not corrosive;

• in case of accidental loss, it does not pollute the soil, water and groundwater.

The lack of toxicity makes LPG also suitable for uses that do not require combustion: thanks to the Montreal Protocol, for example, LPG and its derivatives have replaced CFCs, among the major causes of the ozone hole, previously used in the refrigerator circuits and in sprays.

The ecological qualities of LPG in the transport sector are supported by:
ANPA (National Agency for environmental protection, year 2000)

“[…] it is unequivocally demonstrated a substantial economical and environmental benefit deriving from the use of LPG if compared with petrol for the same vehicle technology”

European parliament (alternative fuels commission):

“[…] LPG is one of the available resources which is able to replace the 20% of conventional fuels (stated goal)”

Legislation and safety

One of ButanGas essential aims is safety: This is the reason why the company invests continuously in modernizing its facilities, in strict compliance with all regulations.
