Fluid distribution for fluid-solid contacting chambers
Abstract
Abstract AN APPARATUS FOR CONTACTING TWO FLUIDS IN A FLUID-SOLIDS CONTACTING ZONE SUCH AS AN ADSORPTION ZONE OR A REACTION ZONE. A FIRST FLUID IS PASSED DOWNWARDLY INTO A DISTRIBUTOR DOWNCOMER AND A SECOND FLUID IS PASSED UPWARDLY INTO THE DOWNCOMER VIA AN INLET NOZZLE CONTAINED WITHIN THE DOWNCOMER. A RESULTING MIXTURE OF FIRST AND SECOND FLUID PASSES DOWNFLOW THROUGH THE ANNULUS CONFINED BETWEEN THE DOWNCOMER WALL AND THE INLET NOZZLE, AND ENTERS A BED FO PARTICULATED SOLIDS BELOW. THE APPARATUS IS ALSO APPLICABLE TO UPFLOW PROCESSING THROUGH BEDS OF PARTICULATED SOLIDS. SPECIFIC APPLICATION IS IN HYDROGENATION, HYDROTREATING, HYDROCRACKING, AND HYDRODEALKYLATION REACTION ZONES, WHEREIN A HYDROGEN STREAM IS UTILIZED FOR THE THERMAL QUENCH OF REACTANT HYDROCARBON BETWEEN CATALYST BEDS.
