According to the invention, the energy storage is obtained by compression of the gas (1, 2, 3) contained in the containers (14, 15, 16) by pumping liquid (9) with the equipment (17). The heat generated by compressing the gas is stored in the medium (10).

Method and apparatus for transporting and treating a natural gas
PURPOSE: To provide a transport and treatment method capable of recovering some additives (hydrat... more PURPOSE: To provide a transport and treatment method capable of recovering some additives (hydrate forming inhibitor and corrosion inhibitor) to recirculate them to the top part of a production well and to also enable the additives to achieve positive function at a time of the treatment applied to gas after the transport at a terminal and capable of avoiding the use of other additives. CONSTITUTION: In a zone G 1 , the gas issuing from a production well 1 is brought into contact with a liquid phase coming at least in part from recycling 4 and containing water and at least one anti-corrosion additive and/or at least one anti-hydrate additive vaporizing an a pure state or an azeotropic form. The gaseous phase loaded with the additives is transported by a conduit 5 to be cooled by a heat exchange E 1 and an aq. phase is separated from a non- condensed gas in a decantation tank B 1 to be recovered by a conduit 10 and the additive-charged aq. phase is recirculated to the contact zone G 1...

Then heated in E1 and E3 the absorbent solution charged with acidic compounds of: to separate two fractions: a first fraction depleted in acidic compounds absorbing solution and a second fraction enriched in acides.Ensuite compounds absorbing solution is separated in BS1 these two fractions. the second fraction is regenerated in C2 so as to release part of the acid compounds, and recycling the first fraction of absorbent solution and the regenerated absorbent solution as an absorbent solution.
