Abstract: Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent into a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is separated for forming an H2-rich stream and a first intermediate liquid phase hydrocarbon stream. The H2-rich stream is contacted with an adsorbent to form an H2-ultra rich stream and a PSA tail gas stream. The PSA tail gas stream is contacted with an H2/hydrocarbon separation membrane to separate the PSA tail gas stream and form an H2-ultra rich permeate stream and a PSA tail gas hydrocarbon-containing non-permeate residue stream.

Abstract: Apparatuses and methods for reforming of hydrocarbons are presented. In one example, a method comprises burning fuel gas to form a hot flue gas and heat a reforming-zone feedstock that contains (C5-C11) hydrocarbons to form a heated reforming-zone feed stream. The heated reforming-zone feed stream is partially reformed to form a partially reformed effluent. The partially reformed effluent is advanced through a process heat recovery coil arrangement that is recovering heat from the hot flue gas to form a heated partially reformed effluent. The heated partially reformed effluent is contacted with reforming catalyst at reforming conditions effective to form a reforming reaction-zone effluent. The reforming reaction-zone effluent comprises H2, C5+ hydrocarbons including aromatics, and C4? hydrocarbons.

Abstract: Embodiments of apparatuses and methods for reforming of hydrocarbons including recovery of products are provided. In one example, a method comprises separating a reforming-zone effluent to form a net gas phase stream and a liquid phase hydrocarbon stream. The net gas phase stream is compressed, partially condensed and cooled, and separated to form an intermediate gas phase stream. The intermediate gas phase stream is cooled to form a cooled intermediate gas phase stream. The liquid phase hydrocarbon stream is cooled to form a cooled liquid phase hydrocarbon stream. The cooled intermediate gas phase stream is contacted with the cooled liquid phase hydrocarbon stream to form an H2-rich stream and a cooled second intermediate liquid phase hydrocarbon stream that is enriched with C3/C4 hydrocarbons. The H2-rich stream is contacted with an adsorbent to form an H2-ultra rich stream.

In one example, an apparatus comprises a separation zone to receive and separate a reforming-zone effluent to form a net gas phase stream and a liquid phase hydrocarbon stream.

In one example, a method comprises separating a reforming-zone effluent to form a net gas phase stream and a liquid phase hydrocarbon stream.

Abstract: 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.

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.

Abstract: 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.

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 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.
