| 20150119232 | SYSTEMS AND METHODS FOR SEPARATING CHLORINE-CONTAINING SPECIES FROM AQUEOUS SOLUTIONS OF CHLORINE-CONTAINING SPECIES - Disclosed is a method for separating a chlorine-containing species from an aqueous solution of the chlorine-containing species in a catalytic hydrocarbon conversion process that includes the step of oxidizing a spent chloride-containing hydrocarbon conversion catalyst, the spent hydrocarbon conversion catalyst including a hydrocarbon residue formed thereon. The oxidizing forms a flue gas including chlorine-containing species, water, and oxides of carbon. The method further includes contacting the flue gas with a water scrubbing stream to dissolve at least a portion of the chlorine-containing species in the water scrubbing stream to form an aqueous acid solution and contacting the aqueous acid solution with a hygroscopic liquid to generate dehydrated hydrogen chloride gas. Still further, the method includes contacting the dehydrated hydrogen chloride gas with additional spent chloride-containing hydrocarbon conversion catalyst to sorb chlorine onto the additional spent chloride-containing hydrocarbon conversion catalyst. | 04-30-2015 |

| 20160059227 | METHODS AND APPARATUSES FOR REGENERATING CATALYST PARTICLES - Apparatuses and methods are provided for regenerating catalyst particles. In one embodiment, a method for regenerating catalyst particles includes passing the catalyst particles through a halogenation zone and a drying zone. The method feeds drying gas to the drying zone and passes a first portion of the drying gas from the drying zone to the halogenation zone. The method includes removing a second portion of the drying gas from the drying zone and injecting a halogen gas into the second portion of the drying gas. Further, the method includes delivering the halogen gas and the second portion of the drying gas to the halogenation zone. In the method, substantially all of the drying gas fed to the drying zone enters the halogenation zone. | 03-03-2016 |
