In an embodiment, a method for processing a hydrocarbon stream includes heating a feed stream in a convective bank. In the method, the feed stream is reacted in a first reaction zone to form a first effluent. The first effluent is heated in a first radiant cell that combusts fuel gas to heat the first effluent and forms a first exhaust gas. The method includes contacting the first exhaust gas with the convective bank to heat the feed stream. | 10-02-2014 |

| 20150057480 | Radial Flow Process and Apparatus - A system for radial flow contact of a reactant stream with catalyst particles includes a reactor vessel and a catalyst retainer in the reactor vessel. The catalyst retainer includes an inner particle retention device and an outer particle retention device. The inner particle retention device and the outer particle retention device are spaced apart to define a catalyst retaining space. The inner particle retention device defines an axial flow path of the reactor vessel, and the outer particle retention device and an inner surface of a wall of the reactor vessel define an annular flow path of the reactor vessel. The system includes an inlet nozzle having an exit opening in fluid communication with the axial flow path, and an outlet nozzle in fluid communication with the annular flow path. The system can further include a fluid displacement device in the axial flow path of the reactor vessel. | 02-26-2015 |
| 20150098862 | Radial Flow Process and Apparatus - A flow connector creates a fluid connection between a port in a wall of a reactor vessel and an axial flow path of the reactor vessel. The flow connector has a wall defining a flow path of the flow connector. The flow path terminates in a first end opening and a second end opening. The first end opening is configured to connect to the axial flow path of the reactor vessel, and the second end opening is configured to connect to the port in a wall of the reactor. The flow connector includes a passageway extending through the wall of the flow connector to provide access to the flow path of the flow connector. A cover is dimensioned for sealing the passageway. The passageway may be dimensioned such that a person may traverse the passageway to access the flow path of the flow connector. | 04-09-2015 |
| 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 |
