CATALYTIC HYDROGENATION PROCESS AND APPARATUS WITH IMPROVED VAPOR-LIQUID SEPARATION

摘要

ABSTRACTA continuous hydrogenation process and apparatus wherein liquids arecontacted with hydrogen in an ebullated catalyst, reaction zone with the liquids andgases flowing vertically upwardly through that zone into a second zone sub-stantially free of catalyst particles and wherein the liquid and gases aredirected against an upwardly inclining surface through which vertical con-duits are placed having inlet ends at different levels in the liquid andhave outlet ends at different levels above the inclined surface, suchthat vapor-rich liquid is collected and discharged through conduits ter-minating at a higher level above the inclined surface than the vapor-poorliquid which is collected and discharged at a level lower than the inclinedsurface.
