Title (EN) COMPOSITION AND PROCESS FOR GAS DEHYDRATION
(FR) COMPOSITION ET PROCÉDÉ DE DÉSHYDRATATION DE GAZ
Abstract:
(EN) The present invention relates to a dehydration composition and method of use thereof for drying gas streams, in particular natural gas streams, wherein the dehydration composition comprises (i) a glycol, (ii) a borate compound, (iii) an alkali metal carboxylate, and (iv) an additional glycol different than (i), and/or (v) an additional additive selected from an alkanolamine, a phosphate acid or salt compound, a sweetening agent, a low temperature viscosity improver, a corrosion inhibitor, an antifoaming agent, or mixtures thereof.
(FR) La présente invention concerne une composition de déshydratation et un procédé d'utilisation de celle-ci pour le séchage de courants gazeux, en particulier des courants de gaz naturel, la composition de déshydratation comprenant (i) un glycol, (ii) un composé de borate, (iii) un carboxylate de métal alcalin et (iv) un glycol supplémentaire différent de (i), et/ou (v) un additif supplémentaire choisi parmi une alcanolamine, un composé acide ou sel de phosphate, un agent édulcorant, un agent améliorant la viscosité à basse température, un inhibiteur de corrosion, un agent antimousse ou leurs mélanges.
