Abstract
A bubble cap assembly and distributor plate is revealed uniquely suited for a reactor in an ebullated bed process. In the riser of the bubble cap assembly a ball check valve is mounted on a valve seat. An orifice mixer below the valve seat delivers a homogeneous vapor-liquid mixture to the orifice in the valve seat thereby minimizing slug flow which causes destructive valve chatter. The fluid outlet port is positioned in the riser to hydraulically limit ball travel between the valve seat and the cap, eliminating the need for pins or other restraints.
