A centrifugal vapor/liquid separator separates the vapor and liquid in a flash of hydrocarbon and steam mixture, such that only the vapor stream is fed and processed further downstream. The design of the separator ensures that all partially wetted surfaces in the separator, except at the vapor outlet pipe, are well-wetted and washed by the non-vaporized liquid portion of the feed or by injection of external liquid thus ensuring that no coke deposition occurs inside the separator. The flash temperature in the separator therefore can be increased beyond the typical limit thus achieving a deeper cut into the feed and recovering a larger fraction of the feed as vapor for further downstream processing.

1. A vapor/liquid separator comprising:a vessel having an inlet for receiving a vapor/liquid mixture; a hub axially located within said vessel at a position below said inlet wherein said hub supports a plurality of vane elements at its proximal end for centrifuging said mixture as said mixture proceeds through said vessel; a vapor outlet axially spaced from the distal end of said hub for withdrawing the vapor phase of said mixture from said vessel; an outlet located below said vapor outlet for withdrawing the liquid phase of said mixture from said vessel; a skirt element located at the distal end of said hub for directing any liquid phase of said mixture in an outward direction away from said hub and toward the walls of said vessel, said skirt having an outer diameter greater than the inlet to said vapor outlet; and means located in said vessel between said inlet and said proximal end of said hub to aid wetting of the head and interior walls of said separator thereby preventing the formation of coke in said head area.
