METHODS AND APPARATUSES FOR REFORMING OF HYDROCARBONS INCLUDING RECOVERY OF PRODUCTS

摘要

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.

1. A method for reforming of hydrocarbons including recovery of products, the method comprising the steps of
(a) separating a reforming-zone effluent that comprises H2, C4− hydrocarbons, and C5+ hydrocarbons including aromatics into a H2, (C1-C11) hydrocarbon-containing gas phase and a C5+ hydrocarbon-containing liquid phase; (b) partially condensing and separating the H2, (C1-C11) hydrocarbon-containing gas phase to form a H2, C6− hydrocarbon-containing net gas stream and a C3+ hydrocarbon-containing liquid stream; and (c) introducing 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 to a re-contacting recovery zone for further separation of H2, C3/C4 hydrocarbons, and/or C5+ hydrocarbons for forming a H2— rich stream, a C3/C4 hydrocarbon-rich LPG stream, and a C5+ hydrocarbon-rich reformate stream.
