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 compressed, partially condensed and cooled to form a partially condensed, compressed net gas phase stream. The partially condensed, compressed net gas phase stream is separated to form an intermediate gas phase stream. The intermediate gas phase stream and the liquid phase hydrocarbon stream are combined to form a two-phase combined stream. The two-phase combined stream is cooled and separated to form an H2-rich stream and a cooled second intermediate liquid phase hydrocarbon stream that is enriched with C3/C4 hydrocarbons and further comprises C5 + hydrocarbons. L'invention concerne des modes de réalisation d'appareils et de procédés pour le reformage d'hydrocarbures comprenant la récupération de produits. Dans un exemple, un procédé consiste à séparer un effluent de zone de reformage pour former un flux net en phase gazeuse et un flux d'hydrocarbures en phase liquide. Le flux net en phase gazeuse est comprimé, partiellement condensé et refroidi pour former un flux net en phase gazeuse comprimé, partiellement condensé. Le flux net en phase gazeuse comprimé, partiellement condensé est séparé pour former un flux intermédiaire en phase gazeuse. Le flux intermédiaire en phase gazeuse et le flux d'hydrocarbures en phase liquide sont combinés pour former un flux combiné biphasique. Le flux combiné biphasique est refroidi et séparé pour former un flux riche en H2 et un deuxième flux intermédiaire d'hydrocarbures en phase liquide refroidi qui est enrichi en hydrocarbures en C3/C4 et comprend en outre des hydrocarbures en C5 +.
