    Starting from 2001, CryoGas has expanded its business to LPGand opened its first gas station in Belgrade. Today we own seven gas stations, and the construction of several new ones is on the way. All our gas stations are continuously at service to our customers – 24 hours a day. .

    What characterizes CryoGas, and what we care most about – is thequality of the gas being sold. With this approach we have gained numerous permanent and loyal customers, especially in Belgrade. Our motto is: SAME PRICE » BETTER ENGINE PERFORMANCE!

    In Belgrade (Palilula – location at Bogoslovija), at our gas station in Dragoslava Srejovića Street No.1, there is also a workshop for the performance and maintenance of gas installations. The workshop is fully equipped and employs workers with many years of experience in the field. In addition, we have also established a gas station in Zaječar, which started operating in early 2008.

    What there is to know about LPG

    Liquified petroleum gas, known in the world by its acronym: LPG –represents a mixture of propane C3H8 and Butana C4H10, , stored at increased pressure, so that both components which are in the gaseous state under normal conditions, are in liquid state. In addition to propane and butane, some other fuel components can be found in the mixture in small quantities (propylene - C3H6, butylene C4H8 etc.), the contents of which are regulated by the appropriate standard.

    In every-day speech, LPG is often mentioned as propane-butane or butane, and in some countries it is called only propane. When intended for household use it is called simply: gas, and when used as car fuel the name: autogas is used.Due to its favourable characteristics, LPG has a very wide application as fuel for households, in industry, in agriculture and as fuel for internal combustion engines.

    TNG

    LPG is obtained in two ways:

    • From natural gas, through the process of fractionation of raw natural gas, during which ethane, propane, butane and other gases are separated. These procedures are carried out in special degasolination units, near the natural gas site.
    • The second method of obtaining LPG is during the processes of primary and secondary oil processing.

    LPG is a gas that is heavier than air, so when potential seepage occurs in the reservoir the gas settles at ground level. If there is a flow of air, the gas will flow along the ground level and accumulate in crevasses, so ignition might occur much farther away from the location of the seepage. Special attention should be paid to this during the placement of storage tanks in case of using LPG in household units.

    From an environmental aspect, LPG is a very favourable fuel. Given that it easily forms a mixture with air, LPG combusts almost completely. Therefore, incomplete combustion products (carbon monoxide – CO, hydrocarbons – HC, carbon – C and particles – PM) exist in negligible amounts..

    In addition, the proportion of hydrogen in the molecules of the compounds that make up the LPG is very high, so the combustion products are dominated by water vapour - H2O, and not CO2. Since CO2is involved in the greenhouse effect, the most recent legislation has limited its content in vehicle exhaust gases to a great extent.Due to lower maximum temperatures of the process, nitrogen oxide emissions have alsobeen significantly reduced.In addition, there are no lead and sulphur compounds in the exhaust fumes, which are also known to have a harmful effect on the environment. In terms of the quality of the exhaust emissions–engines fuelled by LPG surpass the most recent diesel-engines with subsequent exhaust gas treatment.

    The use of gas in internal combustion engines has a very long tradition. Moreover, the first internal combustion engines used different types of gases as propellants. It was only at the beginning of this century that liquid oil derivatives have taken over the primacy among engine fuels, and the reason for this were difficulties in gas production, storage, and handling. Nevertheless, the use of gas in motor vehicles, especially in some specific cases, such as, for example – vehicles intended for internal transport, has never been abandoned as an idea.

    Today, the use of LPG is on the rise – not only because of the growing awareness of the need for environmental protection, but also because of its economic viability. LPG is still considered to be one of the most important alternative fuels for transportation purposes.
