<p>MIXED-PHASE REACTION PRODUCT EFFLUENT SEPARATION PROCESS Multiple-stage separation of a mixed-phase product effluent resulting from the hydrocracking and/or hydrorefining conversion of a hydrocarbonaceous charge stock. Reaction product effluent is initially separated in a high temperature, high pressure first separation zone, the vapor phase from which is cooled and separated in a second separation one to provide a hydrogen-rich vaporous phase. The liquid phase from the second separation zone is inincreased in temperature and separated in a third separation zone at a substantially lower pressure. At least a portion of the liquid phase from the third separation zone is combined with the vaporous phase from the first separation zone prior to cooling and separation in the second separation zone.</p> |
