Abstract

L'invention concerne un procédé et une installation pour dégazer un fluide visqueux. Le fluide est pompé par une pompe centrifuge immergée 14, dont le rouet a un centre creux relié par un arbre creux à un conduit d'aspiration 25, et refoulé par un conduit 24 dans un récipient de pulvérisation 29 dans lequel le fluide est émis en nappe radiale contre la paroi de récipient créant une dépression dans la partie supérieure du récipient raccordée au conduit d'aspiration 25 et imprimant un effort de cisaillement au fluide qui, à la sortie du récipient, entre dans un bac allongé 28 de séparation à la sortie duquel le fluide séparé est renvoyé par un conduit 30 dans un bassin de stockage tandis que le gaz est évacué par un conduit 26. L'invention est applicable au traitement des boues de forage
