Fluid contacting method for fluid-solid contacting chambers

Abstract

Abstract METHOD FOR CONTACTING TWO FLUIDS IN A FLUID-SOLIDS CONTACTING ZONE, SUCH AS AN ADSORPTION ZONE OR A REACTION ZONE. A FIRST FLUID IS PASSED INTO A CENTRAL CHAMBER HAVING A PLURALITY OF FLUID OPENINGS IN THE CHAMBER WALL, WHILE A SECOND FLUID IS PASSED INTO AN ANNULAR CHAMBER ENCOMPASSING THE CENTRAL CHAMBER AND SPACED APART THEREFROM. THE SECOND FLUID IS DISCHARGED VIA FLUID OPENINGS IN THE INNER ANNULAR CHAMBER WALL, INTO AN ANNULAR SPACE BETWEEN THE CHAMBERS, AND THE FIRST FLUID IS DISCHARGED FROM THE CENTRAL CHAMBER INTO THE SECOND FLUID DISCHARGE. A RESULTING FLUID MIXTURE IS PASSED FROM THE ANNULAR SPACE INTO A FIRST CONDUIT MEANS CONFINED WITHIN A SECOND CONDUIT MEANS IN A FIRST DIRECTION OF FLOW. THE MIXTURE IS THEN PASSED INTO AN ANNULAR PASSAGEWAY CONFINED BETWEEN THE FIRST AND SECOND CONDUIT MEANS IN A SECOND DIRECTION OF FLOW SUBSTANTIALLY COUNTERCURRENT TO THE FIRST DIRECTION OF FLOW. THE MIXTURE IS THEN PASSED FROM THE ANNULAR PASSAGEWAY INTO A BED OF PARTICULATED CONTACT SOLIDS. SPECIFIC APPLICATION IS IN HYDROGENATION, HYDROTREATING, HYDROCRACKING AND HYDRODEALKYLATION REACTION ZONES.
