LPG shows certain basic advantages against
the liquid fuels that it is called to substitute
them mainly. As the most important though
comparative advantages of LPG are those mentioned
below:
- Bigger degree of energy efficiency. The increased energy efficiency of LPG has
as result the energy saving, which from a
financial benefit results of course that
is so bigger as bigger is the cost participation
of a fuel to the formation of a total cost
of an activity. The below table indicates
the energy ratio of LPG with the other fuels.

The reasons that lead to the above increased
energy output of LPG and energy saving from
its utility, are the following:
- The high heat energy, 50% bigger that that
of petroleum.
- The lack of sulphur from LPG and consequently
the non-existence of sulphur oxides in exhaust-gases,
permits the use of waste heat recovery without
the danger of corrosions.
