Liquefied Petroleum Gas (LPG)

LPG is a mixture of light hydrocarbons recovered in the oil refining process, composed mainly of butane and propane in various proportions, which are usually of the order of 60% butane and 40% propane.

At atmospheric pressure boiling point is -17 ° C. Are stored and transported in liquid form (hence the name) but they are always accompanied by a camera bag or gas phase. The high octane number and calorific value greater than that of the liquid fuel, along with the fact that at pressures between 5 and 15 bars are liquid, rendering their use as a substitute for the liquid fuels in vehicles for quite feasible over thirty years.

COMPOSITION

It is a fuel that has a chemical composition in which the hydrocarbons butane and propane, or mixtures thereof, which contain major impurities, such as propylene or butylene or a mixture of these predominate.

The butane and propane gases, pure, are hydrocarbons such as:

· CnH2n +2:

· Butane: C4H10

· Propane: C3H8

OBTAINING

The sources of this fuel are refineries (oil distillation) process plants and natural gas, which contribute about 25% and 75% respectively of GLP.
