A process for the removal of water from gas which comprises an absorption step of bringing a gas (1) saturated with water vapour into gas-liquid contact with a water-lean absorbing liquid (3) comprising a water absorbing liquid having a cloud point temperature above the freezing point of water whereby water vapour present in the gas is absorbed into the water-lean absorbing liquid at a temperature below its cloud point to produce a refined gas (4) having a reduced water vapour content and water-loaded absorbing liquid (5) ; and a regeneration step of heating the water-loaded absorbing liquid (5) to above the cloud point temperature of the absorbing liquid whereby the water-loaded absorbing liquid separates into a water-rich phase (7) and an absorbing liquid-rich phase (8) and cooling the absorbing liquid-rich phase to a temperature below its cloud point prior to recycling the absorbing liquid-rich phase for use as water-lean absorbing liquid (3) in the absorption step.

[EN] The present invention relates to a process for the treatment of the product stream from an autothermal cracking reaction, said product stream comprising one or more olefins, hydrogen, carbon monoxide, carbon dioxide, one or more aromatic compounds and one or more organic acid oxygenates, said process comprising reacting the organic acid oxygenates with an alkali at a temperature of at least 70°C. [FR] La présente invention concerne un procédé de traitement d'un courant de produit issu d'une réaction de craquage autotherme, ledit courant de produit comprenant une ou plusieurs oléfines, de l'hydrogène, du monoxyde de carbone, du dioxyde de carbone, un ou plusieurs composés aromatiques et un ou plusieurs oxygénates d'acide organique, ledit procédé comprenant la réaction des oxygénates d'acide organique avec un alcali à une température supérieure ou égale à 70 °C.
