    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 liquid phase hydrocarbon stream. The H2-rich stream may be contacted with an adsorbent to form an H2-ultra rich stream and a gas stream. C3/C4 hydrocarbons are absorbed from the gas stream with the liquid phase hydrocarbon stream. The gas stream may be contacted with an H2/hydrocarbon separation membrane to separate the PSA tail gas stream and form an H2-rich permeate stream and an H2 depleted non-permeate residue stream.

    Abstract: An apparatus for separating a feed stream into product streams. The apparatus includes an upper section, a middle section, and a lower section. The middle section has a dividing wall separating it into two portions. A liquid barrier blocks the flow of liquid from the upper section into the middle section and allows vapor to flow from the middle section to the upper section. A vapor and liquid barrier blocks both the flow of both vapor from the lower section to the middle section and the flow of liquid from the middle section to the lower section. Vapor conduits allow vapor to flow from the lower section to each of the middle portions in varying amounts. Also processes for separating a feed stream.
