    摘要: According to one or more embodiments, particulate solids may be regenerated in a particulate solid treatment vessel. The particulate solid treatment vessel may be connected to a riser. The riser may extend through a riser port of an outer shell of a particulate solid separation section such that the riser may comprise an interior riser segment and an exterior riser segment. The particulate solid separation section may include a gas outlet port, a riser port, and a particulate solid collection area. The riser port may be positioned on a sidewall of the outer shell such that it is not located on a central vertical axis of the particulate solid separation section. The particulate solids may be separated from gasses in the particulate solid separation section.

    摘要: According to one or more embodiments of the present disclosure, a riser may include a lower riser portion, where the lower riser portion terminates at an upper end of the vertical riser segment, and an upper riser portion including a lower end, where the lower end of the upper riser portion may be positioned around the upper end of the vertical riser segment of the lower riser portion. The riser may also include a first guide and a second guide each positioned on opposite sides of the interior of the lower end of the upper riser portion. The vertical riser segment of the lower riser portion may be guided in a direction substantially parallel with the outer surface of the first guide and the outer surface of the second guide when the lower riser portion expands or contracts due to changes in temperature.
