Fluid systems for contacting solid particle material with gaseous and vaporous material

Claim 1

A UNITARY APPARATUS COMPRISING IN COMBINATION, AN UPPER CYLINDRICAL REACTOR CHAMBE, AN INTERMEDIATE CYLINDRICAL STRIPPING CHAMBER AND A LOWER CYLINDRICAL REGENERATOR CHAMBER, EACH OF SAID CHAMBERS ADAPTED TO CONTAIN A RELATIVELY DENSE FLUID BED OF FINELY DIVIDED SOLID PARTICLE MATERIAL THEREIN, SAID STRIPPING CHAMBER IN OPEN COMMUNICATION WITH SAID REACTOR CHAMBER AND EXTENDING DOWNWARDLY FROM THE BOTTOM OF SAID REACTOR CHAMBER, AN OPEN END STANDPIPE EXTENDING DOWNWARDLY FROM SAID STRIPPING CHAMBER THROUGH SAID REGENATOR CHAMBER TO THE LOWER PORTION THEREOF, AT LEAST ONE FIRST RISER CONDUIT EXTENDING FROM THE LOWER PORTION OF SAID REGENERATOR CHAMBER SUBSTANTIALLY VERTICALLY UPWARDLY THROUGH SAID REGENERATOR CHAMBER INTO THE LOWER PORTION OF SAID REACTOR CHAMBER AND EXTERNAL TO SAID STRIPPING CHAMBER, AT LEAST ONE SECOND RISER CONDUIT EXTENDING FROM THE LOWER PORTION OF SAID REGENERATOR CHAMBER SUBSTANTIALLY VERTICALLY UPWARDLY THROUGH SAID REGENERATOR CHAMBER INTO THE INTERMEDIATE PORTION OF SAID RE ACTOR CHAMBER AND EXTERNAL TO SAID STRIPPING CHAMBER, SAID STRIPPING CHAMBER PROVIDED WITH A PLURALITY OF ALTERNATELY STAGGERED DOWNWARDLY SLOPING CONICAL AND FRUSTO-CONICAL BAFFLE MEMBERS WITH THE UPPERMOST CONICAL BAFFLE MEMBER BEING POSITIONED IN THE BOTTOM PORTION OF SAID REACTOR CHAMBER AND THE LOWERMOST CONCIAL BAFFLE MEMBER BEING POSITIONED A SUBSTANTIAL DISTANCE ABOVE THE BOTTOM OF THE STRIPPING CHAMBER TO PROVIDE A DISENGAGING COMPARTMENT IN THE BOTTOM PORTION OF SAID STRIPPING CHAMBER, SAID LOWERMOST CONCIAL BAFFLE MEMBER BEING PROVIDED WITH AN OPEN END CONDUIT EXTENDING FROM THE APEX THEREOF UPWARDLY INTO AN UPPER PORTION OF SAID STRIPPING CHAMBER, A PLURALITY OF VERTICALLY SPACED APART INDEPENDENTLY CONTROLLED MEANS FOR INTRODUCING GASEOUS MATERIAL TO SAID STRIPPING CHAMBER, MEANS FOR INTRODUCING REACTANT MATERIAL TO THE BOTTOM PORTION OF EACH OF SAID RISER CONDUITS, MEANS FOR INTRODUCING GASEOUS MATERIAL TO THE BOTTOM PORTION OF SAID REGENERATOR CHAMBER, AND MEANS FOR REMOVING GASEOUS MATERIAL FROM THE UPPER PORTION OF SAID REACTOR CHAMBER AND SAID REGENERATOR CHAMBER.
