Abstract

Methods and apparatus for controlling the flow of solids in systems containing solid/fluid slurries is disclosed. An L-valve, having subsequent thereto a separator for separating the solid and fluid phases of the slurry, and a way to regulate the flow of the separated fluid permits the opening and closing of the L-valve without the necessity of mechanical valving systems in contact with the solid phase. A novel L-valve design comprising a radial barrier above a vertical outlet which barrier is of sufficient dimension to permit the solids to attain their angle of repose before reaching the outlet is also disclosed.
