Dry gas
GOST 5542-87, OST 51-40-93
Dry gas is produced by petroleum gas processing; it belongs to Toxicity Class IV.
Dry gas is used as commercial and domestic fuel, and also as a raw material at chemical plants producing fertilizers and other articles.
Ethane fraction
TU 0272-022-00151638-99
It is a valuable raw material for petrochemistry, which is used to produce ethylene. Ethylene, in its turn, is used to produce ethanol, glycerin, ethylene glycol, dichloroethane, ethyl-chloride, etc. The subsequent processing of these substances gives varnishes, solvents, paints, detergents, polyethylene.
Liquefied hydrocarbon gases
GOST 20448-90
They are flammable and explosive, and have a specific odor. Owing to their impact on human health, these gases are categorized as Class IV. They are used as domestic fuel and for industrial applications.
Liquefied gases must comply with the following requirements:

Stabilized natural gasoline
TU 39-1340-89
A mixture of saturated С3 - С6 and heavier hydrocarbons.
A flammable explosive liquid, belonging to Toxicity Class IV. It is produced by the processing of the associated petroleum gas.
There are two gasoline grades (light and heavy gasoline), depending on the raw gas composition, gasoline production method, and its physical and chemical properties.
The stabilized natural gasoline is used as a raw material for pyrolysis in petrochemical and organic synthesis plants, in gas fractionation plants and also for compounding the automotive gasolines.
