Liquefied Petroleum Gases (LPG)

LPG stands for liquefied petroleum gas. Like all fossil fuels, it is a non-renewable source of energy. It is extracted from crude oil and natural gas. LPG is composed hydrocarbons containing three or four carbon atoms. The normal components of LPG thus, are propane (C3H8) and butane (C4H10). Small concentrations of other hydrocarbons may also be present.

LPG burns readily in air and has an energy content similar to petrol and twice the heat energy of natural gas. This makes it an excellent fuel for heating, cooking and for automotive use.

Normally, the gas is stored in liquid form under pressure in a steel container, cylinder or tank. The pressure inside the container will depend on the type of LPG (commercial butane or commercial propane) and the outside temperature.

Type
Propane-Butane Mixture (LPG-Mix, SPBT)
PROPANE (C3H8)
N-BUTANE (C4Н10)
ISO-BUTANE (iC4H10)

Propane-Butane Mixture (LPG-Mix, SPBT)

Under normal circumstances LPG Mix in the gas state, but with a slight increase in pressure - turns into a liquid state. Is obtained by mixing the hydrocarbon fractions after fractionation of broad fraction of light hydrocarbons.

LPG Mix is used for fuel purposes and is supplied to the population and industry both domestically and for export.

LPG Mix is a flammable and explosive liquid of the 4th toxicity class. It is produced by mixing of hydrocarbon fractions after fractionation of NGL-SHFLU.
