ABSTRACT:
A process for the treatment or processing and transportation of a natural gas from a gas well to a reception and treatment or processing terminal comprises, in a zone in the producing well, contacting the natural gas and a recycled liquid phase containing water and at least one anti-hydrate additive and/or at least one anti-corrosion additive, both of which being at least partly miscible with water and which vaporize in the pure state or as an azeotrope. The resultant additive-containing gaseous phase is cooled to form an uncondensed and a condensate. The condensate containing substantially all of the additive is separated from the uncondensed gas and is recycled to the contact zone in the producing well.
