Abstract: The method involves drawing off of a solid flow by a down pipe (6), and fluidizing the solid flow on a base (8) of the down pipe by a supply of carrier gas. The solid flow is transported to a high level by an ascending pipe (9) branched off by the down pipe, and dimension of the solid flow extracted by the ascending pipe is varied by variable supply of the carrier gas. The level of the flow or solid stock in a solid container is used as a controlled variable, and a volume flow of the carrier gas is used as a correcting variable of a control loop. Independent claims are also included for the following: (1) a method for regulating a temperature and/or mixing ratio in a mixing vessel (2) a device for regulating a level and/or solid stock in a solid container.

Abstract: For dividing a stream of solids, which is withdrawn from a fluidized-bed tank, the stream of solids is discharged via a first downer and fluidized at the bottom of the first downer by supplying a fluidizing gas, wherein at least part of the stream of solids is conveyed to the top via a first riser branching off from the downer, wherein the remaining part of the stream of solids is discharged via a second downer adjoining the first downer and is fluidized at the bottom of the second downer by supplying a fluidizing gas, and wherein at least part of the stream of solids is conveyed to the top via a riser branching off from the second downer.

Abstract: The present invention relates to the production of metal oxide from metal salts, in particular from aluminum hydroxide, wherein the metal salt is preheated in a first preheating stage, precalcined in a second preheating stage and calcined to metal oxide in a fluidized-bed reactor, and wherein the product obtained then is cooled in at least one suspension heat exchanger and subsequently in a multi- stage indirect cooler. To reduce the energy demand of a calcining plant, fluidizing air is supplied to the reactor with a temperature of up to 150 °C, and before entering the first preheating stage the metal salt is at least partly supplied to a hydrate drier in which it is indirectly heated with heat transfer medium from the first stage of the indirect cooler and dried.

Abstract: A process for producing metal oxide from a metal salt includes supplying a first part of the metal salt to a hydrate drier so as to indirectly heat the first part of the metal salt in the hydrate drier using a heat transfer medium from a first stage of a multi-stage indirect cooler so as to dry the first part of the metal salt in the hydrate drier and so as to control a waste gas temperature of the process. A second part of the metal salt is guided as a partial stream past the hydrate drier. The metal salt is preheated in a first preheating stage and precalcined in a second preheating stage. The metal salt and a fluidizing gas having a temperature of 150° C. or less are supplied to a fluidized bed reactor so as to calcine the metal salt to form a metal oxide product. The metal oxide product is cooled in at least one suspension heat exchanger and then in the multi-stage indirect cooler.
