Abstract
A process for discharging solids from a vessel having at least three successive beds of solid particulate material with at least two of the beds being of different solid material than the other. The process comprises opening a lowermost closure and discharging the lowermost bed from the vessel while maintaining other closures in closed positions. After discharging the lowermost bed, opening the next-to-lowermost closure to permit the next-to-lowermost bed of solids to replace the lowermost bed, and repeating this operation up through all the beds without mixing of the beds, and discharging each bed separately from the vessel.
