Abstract:
Device for storing and releasing fluids at nearly constant pressure, the fluids including a gas and a liquid, includes an assembly of substantially identical reservoirs (1), where the reservoirs include: a portion containing the gas (G) and a portion containing the liquid (L), an element (23) of separation between the gas and the liquid in the reservoir (1), an inlet orifice (36) and an outlet orifice (36) for the gas, an inlet orifice (35) and an outlet orifice (35) for the liquid. The reservoirs (1) have a cylindrical outer envelope (100) made up of at least one metal tube (101) of the type of those used for gas pipelines and oil pipelines, for which: the external diameter is more than 32 inches (813 mm); and the ratio of the length thereof to the outer diameter thereof is greater than 8.
