SLURRY DELIVERY CONTROL APPARATUS AND METHOD

摘要

An apparatus and method for controlling a flow of a slurry (54) having an outer bypass loop (76) configured to carry the slurry from a source (52) and containing a first upstream valve (66) and a first downstream valve (82) connected by an outer conduit (70). A splitter valve (120) is positioned between the first upstream valve (66) and the first downstream valve (82) to receive aflow from the outer conduit. An inner bypass loop (88) is provided containing an upstream portion of the outer conduit (70) in fluid communication with a second upstream valve (96) and a second downstream valve (100).
