CONTROLLING SOLIDS CIRCULATION IN A GAS-SOLIDS REACTION SYSTEM

This invention provides a method for controlling solids circulation in a gas-solids reaction system. The method entails aerating solid particles in a standpipe. Aeration fluid is injected into the standpipe at the appropriate location to increase apparent density of the solid particles. La présente...

Zusammenfassung:	This invention provides a method for controlling solids circulation in a gas-solids reaction system. The method entails aerating solid particles in a standpipe. Aeration fluid is injected into the standpipe at the appropriate location to increase apparent density of the solid particles. La présente invention concerne un procédé permettant de maîtriser la circulation des solides dans un système de réaction enter gaz et solides. Ce procédé nécessite d'aéré les particules solides dans une colonne montante. En l'occurrence, on injecte un fluide d'aération dans la colonne montante en un endroit choisi pour augmenter la densité apparente des particules solides.
