WIPO Patent Application WO/2011/112232
Kind Code:
A3
Abstract:
A gas-solids contactor modification is described which provides for starting or restarting the gas flow to the gas-solids contactor when it is filled with solid particles while preventing the solids from entering and blocking one or more gas inlets which have diameters greater than the solid particle diameters The apparatus modification comprises a gas plenum and one or more chambers within the gas plenum located between the contactor inlet and the gas inlet The wall of the chamber has multiple passageways therethrough that are smaller in diameter than the majority of the bed particles Gas feed to the plenum must pass through the passageways in the chamber walls before entering the contactor. In one embodiment the total open area of the passageways is at least as large as the cross-sectional area of the gas inlet and the inlet to the contactor
