Definitions

  • Mixing valve 20 provides a means for mixing the water with the crude to ensure that the washing process takes place.
  • the mixture emerging from the mixing valve 20 is then passed by means of inlet 22 into the separating vessel 23 wherein by gravity, the more dense water phase migrates towards the bottom of the vessel into a layer 30 with the less dense oil phase migrating to the top of the vessel into a layer 26.
  • a mid-layer or interface layer 32 is formed in the vessel and is comprised of a suspension or emulsion of oil and water which is sometimes referred to as a "rag" layer.

Abstract

Un système de séparation huile/eau est constitué d'un récipient séparateur dans lequel se forme une couche de fluide (32) émulsifiée finement dispersée à l'interface d'une couche d'eau (26) et d'une couche d'huile (30). On fait passer un courant (34) de couche d'émulsion (32) par un séparateur hydrocyclone (40) afin de séparer et de faire sortir le constituant le plus dense et le constituant le moins dense (70) dudit courant (34) de couche d'émulsion. Le constituant le plus dense (48) du courant est ramené à la couche émulsifiée (32) dans le récipient séparateur (23). Le constituant le moins dense (70) du courant (34) est ramené à la couche d'huile (26) dans le récipient (23). L'invention prévoit également des éléments permettant d'injecter des substances chimiques dans les courants à différents endroits (54, 68) du système afin d'améliorer la séparation.
