Apparatus for cross-flow contacting of a fluid with particulate solids in a magnetically-stabilized bed of said solids, and processes using same.

摘要

Apparatus for cross-flow contacting of fluids with particulate solids in a magnetically-stabilized bed of said solids comprises a contactor chamber (2) having vertical walls with fluid inlet openings (8) in one part of the vertical walls and fluid outlet openings (9) in an opposite part of the walls. A magnet or solenoid (4) around the chamber (2) generates a vertical magnetic field. Particulate solids (6) having ferromagnetic properties are passed from an inlet (14) into the top of the chamber (2) where they form a bed which is structured and stabilized by the magnetic field. Solids are recovered from the bottom of the chamber (2) from an outlet (16). The apparatus can be employed in a process for removing particles entrained in the cross-flowing fluid and/or to remove chemical species therefrom. When the fluid passing into the apparatus is a flue gas containing SOx and entrained particles, and when the ferromagnetic particles are associated with an SOx-capture substance such as Cu, the flue gas leaving the apparatus is of reduced SOx and entrained particles content.
