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 to form 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 intermediate liquid phase hydrocarbon stream. The H2-rich stream is contacted with an adsorbent to form an H2-ultra rich stream and a pressure swing adsorption (PSA) tail gas stream. The PSA tail gas stream and at least a portion of the liquid phase hydrocarbon stream are combined and cooled to form a cooled two-phase combined stream. The cooled two-phase combined stream is separated into a H2, C2−hydrocarbons-containing gas stream and a cooled second intermediate liquid phase hydrocarbon stream.
