Abstract
In an ebullated bed reactor it has been found that an improved gas-liquid separator effectively removes gas from recycle liquid used to ebullate the catalyst bed. The gas-liquid separator comprises a cup with a plurality of riser conduits. Helical members are positioned within the riser conduits which impart a tangential velocity component to the fluid. Cyclone separators effect the final liquid-vapor separation. Vapor is directed to a vapor rich zone in the reactor.
