Hydrocarbon cracking apparatus
Abstract
Abstract APPARATUS FOR CRACKING HIGH-BOILING HYDROCARBONS TO FORM OLEFINS, WITH CIRCULATING, HIGHLY HEATED, FINE-GRAINED HEAT CARRIERS IN A FLUIDIZED BED. IN THE APPARATUS, THE HEAT CARRIERS ARE ELEVATED AND HEATED IN THE VERTICAL PNEUMATIC LINE, SEPARATED FROM THE CONVEYING AND HEATING GASES AND SORTED IN A GREATLY ENLARGED SEPARATOR CHAMBER, AND SUPPLIED THROUGH A CONDUIT TO THE REACTOR. THE REACTOR HAS A PLURALITY OF INDIVIDUAL NOZZLES PROVIDED WITH INDIVIDUAL INLET CONDUITS AND EXTENDING THROUGH THE BOTTOM OF THE REACTOR TO SUPPLY THE HYDROCARBONS TO BE CRACKED. A LATERAL OUTLET IS CONNECTED TO THE LOWER PORTION OF THE FLUIDIZED BED AND SERVES TO RETURN THE HEAT CARRIES TO THE CONVEYING AND HEATING LINE. THE CONNECTIONS BETWEEN THE REACTOR AND A CYCLONE FOR SEPARATING ENTRAINED FINE-GRAINED HEAT CARRIERS, AND BETWEEN THE CYCLONE AND A QUENCHER, ENSURE THE FLOW PATHS OF THE CRACKED GAS WILL BE KEPT FREE OF DEPOSITS. THE CONNECTIONS COMPRISE A TRANSFER DUCT BETWEEN THE REACTOR AND THE SEPARATING CYCLONE, AND DISCHARGE DUCT BETWEEN THE SEPARATING CYCLONE AND THE QUENCHER.
