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 H2, C6− hydrocarbon-containing gas phase and a C5+ hydrocarbon-containing liquid phase. The H2, (C1-C11) hydrocarbon-containing gas phase is partially condensed and separated to form a H2, C6− hydrocarbon-containing net gas stream and a C3+ hydrocarbon-containing liquid stream. The C5+ hydrocarbon-containing liquid phase, the C3+ hydrocarbon-containing liquid stream, and at least a portion of the H2, C6− hydrocarbon-containing net gas stream are introduced to a re-contacting recovery zone for forming a H2-rich stream, a C3/C4 hydrocarbon-rich LPG stream, and a C5+ hydrocarbon-rich reformate stream.
