Abstract:
(EN) There is provided a process for the prevention or reduction of surge wave instabilities during the transport in a flowline of a three phase gas condensate comprising a gas phase, an aqueous phase and a condensate phase, characterized in that a dispersing agent is added to the three phase gas condensate which is able to disperse the aqueous phase in the condensate phase or the condensate phase in the aqueous phase, and a means for the prevention or reduction of surge wave instabilities during the transportation of a three phase gas condensate.
(FR) L'invention concerne un procédé s'appliquant à la prévention ou à la réduction des instabilités d'ondes de translation pendant le transport dans une conduite d'écoulement d'un condensat de gaz à trois phases comprenant une phase gazeuse, une phase aqueuse et une phase de condensat, et caractérisé en ce qu'un agent de dispersion est ajouté à la phase de condensat qui peut disperser la phase aqueuse dans la phase de condensat ou la phase de condensat dans la phase aqueuse, et un moyen pour la prévention ou la réduction des instabilités d'ondes de translation pendant le transport d'un condensat de gaz à trois phases.
