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: A portion of the overhead vapor from a distillation column is used to heat a process stream. The temperature and flow rate of the stream out of a heat exchanger are controlled so that the vapor is condensed.
