Abstract

L'invention concerne un procédé d'inhibition de l'accumulation de dépôt de DSP dans le circuit de liqueur d'un équipement du procédé Bayer. Le procédé comprend l'addition d'une ou plusieurs petites molécules à base de silane particulaire au circuit de fluide de liqueur. Ces inhibiteurs de dépôt réduisent la formation de dépôt de DSP et par là augmentent le débit de fluide de sortie, augmentent le laps de temps pendant lequel l'équipement du procédé Bayer peut être opérationnel et réduisent le besoin de lavages acides coûteux et dangereux de l'équipement du procédé Bayer. Par conséquent, l'invention permet une réduction significative du coût total du fonctionnement d'un procédé Bayer.
