The component composition of liquefied gas is regulated by DSTU 4047-2001. Liquefied petroleum gases (LPG) are a mixture of liquefied light hydrocarbons under pressure with boiling points ranging from -50 to 0 °C. They are intended for use as fuel and also serve as raw materials for organic synthesis.
The composition of LPG can vary significantly. Its main components are propane, isobutane, and n-butane. To transport LPG by railway, special design railway tank cars are used. Specialized road trains are also employed for transportation. LPG is one of the most widely used motor fuels in the world.
