The production of liquefied petroleum gas (LPG) is one of the fastest growing sectors of the global energy market. LPG is actively used as a fuel for internal combustion engines of cars, sea vessels, agricultural machinery and aviation. The gas filling station in Vitebsk has mastered a proven technology for mixing and making mixtures and produces liquefied gas of the European standard. With regard to the physicochemical and operational parameters, export grade LPG meets the requirements and norms stipulated by the European standard PN-EN 589 + A1:2012 «Fuels for Internal Combustion Engines. Liquefied Petroleum Gas (LPG). Technical requirements».

Normal butane fraction is produced in a gas fractionation plant and is essentially comprised of butane (not less than 98.6% for the High grade, 97.5% for grade A) with small amounts of accompanying hydrocarbons. It is used as a raw material for the production of butadiene in the manufacture of synthetic rubber, for pyrolysis, as well as for other purposes. Normal butane fraction is a low-risk product and, according to the degree of exposure to the human body, belongs to the 4th hazard class in accordance with GOST 12.1.007.

Normal butane is used both for domestic consumption and industrial purposes. When mixed with propane, it is used as a domestic fuel and a smokeless autogas. It is also used as a solvent — for dewaxing and deasphalting of petroleum products, in the polymerization of vinyl esters and for the extraction of fats, as well as for the production of soot. When mixed with oxygen, it is used for cutting metals. It is soluble in organic solvents. At ordinary temperatures, it is chemically inert. At high temperatures it is completely burned out with the formation of carbon dioxide and water. It forms explosive mixtures with air in certain concentrations.
With regard to the physicochemical and operational parameters, normal butane meets the following requirements and norms:

Isobutane is a colourless, odourless gas that is dissolved in organic solvents. It is contained in gas condensate and petroleum gases. It is combustible. It is a product of catalytic and hydrocatalytic cracking of petroleum fractions. The main use of isobutane in the industry is the raw material for the production of isobutylene, which in turn is the raw material for the production of butyl rubber. Due to its high octane number (100), isobutane is used as a fuel component for internal combustion engines. Moreover, isobutane is often used as a filler in aerosol cans. Isobutane is a low-risk product and, according to the degree of exposure to the human body, belongs to the 4th hazard class in accordance with GOST 12.1.007.
