Process for contacting corrosive gases with solid desiccant in the oxidation of an inorganic halide

Claim 2

A CONTINUOUS PROCESS FOR THE PRODUCTION OF AN ELEMENTAL HALOGEN WHICH COMPRISES THE STEPS IN COMBINATION: IN A REACTOR HAVING A REACTION zONE AND A FIRST STRIPPING ZONE, CATALYTICALLY REACTING AN INORGANIC HALIDE WITH AN

Claim 3

A CONTINUOUS PROCESS FOR THE PRODUCTION OF CHLORINATED HYDROCARBONS WHICH COMPRISES THE STEPS IN COMBINATION: IN A REACTOR, HAVING A REACTION ZONE AND A LOWER FIRST STRIPPING ZONE, CATALYTICALLY REACTING HYDROGEN CHLORIDE, WITH OXYGEN IN THE PRESENCE OF A HYDROCARBON AND A SOLID DESICCANT AT AN ELEVATED TEMPERATURE UNDER FLUIDIZED SOLIDS CONDITIONS TO EFFECT THE FORMATION OF CHLORINATED HYDROCARBON PRODUCT AND WATER AND ABSROBING THE WATER IN THE DESICCANT AS IT IS FORMED, REMOVING THE GASEOUS CHLORINATED PRODUCT EFFLUENT FROM THE UPPER PORTION OF THE REACTION ZONE; WITHDRAWING AND PASSING WET SOLIDS FROM THE BOTTOM OF THE REACTION ZONE DOWNWARDLY INTO THE FIRST STRIPPING ZONE IN COUNTERCURRENT CONTACT WITH OXYGEN AS THE STRIPPING GAS TO REMOVE AND RECOVER ANY ENTRAINED CHLORINATED PRODUCT FROM THE SOLIDS; PASSING THE RECOVERED CHLORINATED PRODUCT TOGETHER WITH OXYGEN UPWARDLY INTO THE REACTION ZONE, WITHDRAWING THE WET SOLIDS DOWNWARDLY FROM SAID STRIPPING ZONE AND PASSING THEM TO A SEPARATE REGENERATOR CONTAINING A REGENERATION ZONE, A LOWER COOLING ZONE AND A BOTTOM STRIPPING ZONE, DRYING THE WET SOLIDS IN THE REGENERATION ZONE; RETURNING A PORTION OF THE REGENERATED SOLIDS TO SAID FIRST STRIPPING ZONE; PASSING ANOTHER PORTION OF REGENERATED SOLIDS THROUGH THE LOWER COOLING ZONE TO REDUCE THE TEMPERATURE OF SOLIDS AT LEAST 250* BELOW THE REACTION TEMPERATURE; PASSING THE ENTIRE PORTION OF COOLED SOLIDS DOWNWARDLY THROUGH THE SECOND STRIPPING ZONE IN COUNTER-CURRENT CONTACT WITH AIR AS THE STRIPPING GAS TO REMOVE ENTRAINED FLUE GASES, PASSING THE FLUE GASES AND AIR UPWARDLY THROUGH THE COOLING ZONE AND REGENERATION ZONE TO MAINTAIN FLUIDIZED CONDITIONS IN THESE ZONES; ADMIXING THE SOLIDS FROM THE SECOND STRIPPING ZONE WITH THE GASEOUS PRODUCT EFFLUENT TO EFFECT DIRECT HEAT EXCHANGE; PASSING THE GASEOUS AND SOLIDS MIXTURE TO A SEPARATE PRODUCT EFFLUENT DRYING ZONE WHEREIN TEMPERATURE EQUILIBRIUM IS ATTAINED AND WATER, AT A LOWER VAPOR PRESSURE AS COMPARED WITH THE VAPOR PRESSURE IN THE REACTION ZONE, IS ADSORBED BY THE DESICCANT; MAINTAINING FLUIDIZED SOLIDS CONDITIONS IN THE PRODUCT EFFLUENT DRYING ZONE; SEPARATING THE GASEOUS CHLORINATED PRODUCT EFFLUENT FROM THE SOLIDS AND RECOVERING ANHYDROUS CHLORINATED HYDROCARBON FROM THE GASEOUS PRODUCT EFFLUENT WITHDRAWN FROM THE TOP OF SAID PRODUCT EFFLUENT DRYING ZONE; AND PASSING THE DESICCANT FROM THE LOWER PORTION OF THE PRODUCT EFFLUENT DRYING ZONE TO THE REACTION ZONE TO MAINTAIN A CONSTANT REACTION TEMPERATURE AND FOR REPEATED CONTACT WITH REACTANT GASES THEREIN.

Claim 4

A CONTINUOUS PROCESS FOR THE PRODUCTION OF CHLORINATED HYDROCARBONS WHICH COMPRISES THE STEPS IN COMBINATION: IN A REACTOR, HAVING A REACTION ZONE AND A LOWER FIRST STRIPPING ZONE, CATALYTICALLY REACTING HYDROGEN CHLORIDE, WITH OXYGEN IN THE PRESENCE OF A HYDROCARBON AND A SOLID DESICCANT AT AN ELEVATED TEMPERATURE UNDER FLUIDIZED SOLIDS CONDITIONS TO EFFECT THE FORMATION OF CHLORINATED HYDROCARBON PRODUCT AND WATER AND ABSROBING THE WATER IN THE DESICCANT AS IT IS FORMED, REMOVING THE GASEOUS CHLORINATED PRODUCT EFFLUENT FROM THE UPPER PORTION OF THE REACTION ZONE; WITHDRAWING AND PASSING WET SOLIDS FROM THE BOTTOM OF THE REACTION ZONE DOWNWARDLY INTO THE FIRST STRIPPING ZONE IN COUNTERCURRENT CONTACT WITH OXYGEN AS THE STRIPPING GAS TO REMOVE AND RECOVER ANY ENTRAINED CHLORINATED PRODUCT FROM THE SOLIDS; PASSING THE RECOVERED CHLORINATED PRODUCT TOGETHER WITH OXYGEN UPWARDLY INTO THE REACTION ZONE, WITHDRAWING THE WET SOLIDS DOWNWARDLY FROM SAID STRIPPING ZONE AND PASSING THEM TO A SEPARATE REGENERATOR CONTAINING A REGENERATION ZONE, A LOWER COOLING ZONE AND A BOTTOM STRIPPING ZONE, DRYING THE WET SOLIDS IN THE REGENERATION ZONE; RETURNING A PORTION OF THE REGENERATED SOLIDS TO SAID FIRST STRIPPING ZONE; PASSING ANOTHER PORTION OF REGENERATED SOLIDS THROUGH THE LOWER COOLING ZONE TO REDUCE THE TEMPERATURE OF SOLIDS AT LEAST 250* BELOW THE REACTION TEMPERATURE; PASSING THE ENTIRE PORTION OF COOLED SOLIDS DOWNWARDLY THROUGH THE SECOND STRIPPING ZONE IN COUNTER-CURRENT CONTACT WITH AIR AS THE STRIPPING GAS TO REMOVE ENTRAINED FLUE GASES, PASSING THE FLUE GASES AND AIR UPWARDLY THROUGH THE COOLING ZONE AND REGENERATION ZONE TO MAINTAIN FLUIDIZED CONDITIONS IN THESE ZONES; ADMIXING THE SOLIDS FROM THE SECOND STRIPPING ZONE WITH THE GASEOUS PRODUCT EFFLUENT TO EFFECT DIRECT HEAT EXCHANGE; PASSING THE GASEOUS AND SOLIDS MIXTURE TO A SEPARATE PRODUCT EFFLUENT DRYING ZONE WHEREIN TEMPERATURE EQUILIBRIUM IS ATTAINED AND WATER, AT A LOWER VAPOR PRESSURE AS COMPARED WITH THE VAPOR PRESSURE IN THE REACTION ZONE, IS ADSORBED BY THE DESICCANT; MAINTAINING FLUIDIZED SOLIDS CONDITIONS IN THE PRODUCT EFFLUENT DRYING ZONE; SEPARATING THE GASEOUS CHLORINATED PRODUCT EFFLUENT FROM THE SOLIDS AND RECOVERING ANHYDROUS CHLORINATED HYDROCARBON FROM THE GASEOUS PRODUCT EFFLUENT WITHDRAWN FROM THE TOP OF SAID PRODUCT EFFLUENT DRYING ZONE; AND PASSING THE DESICCANT FROM THE LOWER PORTION OF THE PRODUCT EFFLUENT DRYING ZONE TO THE REACTION ZONE TO MAINTAIN A CONSTANT REACTION TEMPERATURE AND FOR REPEATED CONTACT WITH REACTANT GASES THEREIN.
