METHODE ET APPAREIL POUR METTRE EN CONTACT CONTINU UN FLUIDE ETUN SOLIDE

摘要

A method and apparatus for removing a first component from a fluid stream comprises contacting the fluid stream with a continuously moving bed of filter material, contained within a separation column, recovering the contaminated filter material, and regenerating it for reuse. The continuously moving bed of filter material is moved through a contact zone in the separation column by creating a hydraulic force on the material from the flow of a carrier liquid through the material. The fluid stream can be an oil-water mixture from which oil is removed by an absorbent filter material.
