ABSTRACT:
For hot hydrocarbon liquids and slurries containing a vapor portion derived from a hydrogenation process, the vapor portion is separated from the liquid portion within a separation zone by providing a liquid vortex flow pattern having a gas core. The vapor is withdrawn from the vortex core through an inwardly-extending conduit, and the remaining rotating liquid portion is passed to below the vortex. If catalyst particles are also contained in the hot hydrocarbon liquid, such as in a coal or oil hydrogenation reaction effluent liquid at elevated temperature and pressure conditions, such catalysts can be conveniently separated from a product liquid stream and returned to the reaction zone along with the recycled liquid. A clean liquid stream is withdrawn from the recycled liquid for further processing. If desired, the phase separation zone utilizing a liquid vortex can be provided within the catalytic reaction zone.
