Methods and apparatuses for reforming of hydrocarbons including recovery of products

An apparatus for reforming of hydrocarbons including recovery of products, the apparatus comprising:

• a hot separator configured to receive and separate a reforming-zone effluent that comprises H2, C4− hydrocarbons, and C5+ hydrocarbons including aromatics to form a H2, (C1-C11) hydrocarbon-containing gas phase and a C5+ hydrocarbon-containing liquid phase;
• a heat exchanger in fluid communication with the hot separator to partially cool the C5+ hydrocarbon-containing liquid phase;
• a product condenser configured to receive and partially condense the H2, (C1-C11) hydrocarbon-containing gas phase to form a partially condensed H2, (C1-C11) hydrocarbon-containing stream;
• a product separator configured to receive and separate the partially condensed H2, (C1-C11) hydrocarbon-containing stream to form a H2, C6− hydrocarbon-containing net gas stream and a C3+ hydrocarbon-containing liquid stream;
• a re-contacting recovery zone in fluid communication with the hot separator and the product separator to receive 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 and configured to further separate H2, C3/C4 hydrocarbons, and/or C5+ hydrocarbons to form a H2-rich stream and at least one liquid phase stream that comprises C3+ hydrocarbons, wherein the re-contacting recovery zone comprises:
• a plurality of re-contact drums in fluid communication with each other for separating liquid and/or gas phase fractions of the C5+ hydrocarbon-containing liquid phase, the C3+ hydrocarbon-containing liquid stream, and the at least the portion of the H2, C6− hydrocarbon-containing net gas stream to further separate H2, C3/C4 hydrocarbons, and/or C5+ hydrocarbons, the plurality of re-contact drums including an initial stage re-contact drum, an intermediate stage re-contact drum that is downstream from the initial stage re-contact drum, and an end stage re-contact drum that is downstream from the intermediate stage re-contact drum;
• and
• a stabilizer in fluid communication with the re-contacting recovery zone to receive and separate the at least one liquid phase stream to form a C3/C4 hydrocarbon-rich LPG stream and a C5+ hydrocarbon-rich reformate stream.
