Gas tanks are widely used, including in the oil storage facilities to avoid losses in small and large breathing of the tank farms, as well as in the chemical and nuclear plants.

Structure and principle of operation
1 cubic meter of steam-air mixture contains from 1 to 2 liters of reduced gasoline. The oil storage facility or liquid terminal equipped with gasholders – recuperators produces up to 1,500 litres of condensate of each 1 000 cubic meters of crude oil or gasoline. Unlike the "floating roofs", elastic gasholders-recuperators of NPF "Politechnika” are hermetically connected to the gas equalization binding of the tank farm of the oil storage facility and accumulate hydrocarbon vapors both during the filling of the tanks with oil products (large breathing) and during thermal evaporation (small breathing). When the oil product is drained from the tanks, the hydrocarbon vapors return to the released volume of the tanks, forming a closed "tank — gasholder" system. Among other things, such a system ensures compliance with environmental standards, preventing emissions of petroleum vapor into the atmosphere.
Elastic tanks produced by NPF "Politechnika" are made of new composite elastomers. The materials are characterized by exceptional chemical resistance to concentrated hydrochloric and sulfuric acids (which is important in the industries including the enrichment of precious metal ores), as well as to methanol (hydrate inhibitor in oil and gas production).
The composite consists of seven layers (two of them - barrier polyamide). This design radically reduces the diffusion through the shell of both the storage product and the moisture and air from the outside. The thickness of the barrier layer reaches 60 microns.
To prevent the accumulation of static electricity the composition of the polymers includes special hydrophilic additives that completely eliminate the risk of spark breakdown.
