Process of transferring particulate solids out of a fluidized bed

摘要

Process of transferring particulate solids out of a fluidized bed having a bulk density in the range of 0.32 0.64 g/cm<3> via a standpipe, protruding into said fluidized bed through the bottom wall of said fluidized bed, wherein the inlet of said standpipe for receiving particulate solids from the fluidized bed is located close to said bottom wall at a position where the local density is above 0.64 g/cm<3>.
