Abstract: A PROCESS OF CONTINUOUSLY CONVEYING GRANULAR SOLIDS FROM A FIRST ZONE WITH A PRESSURE OF 0.4 TO 1.6 MPA (4 TO 16 BAR) THROUGH A DESCENDING LINE AND VIA AN ASCENDING LINE TO A SECOND ZONE WITH A PRESSURE WHICH IS LOWER THAN IN THE FIRST ZONE BY 0.3 TO 1.5 MPA (3 TO 15 BAR) , BY MEANS OF A GASEOUS MEDIUM.TO ENSURE THAT THE PRESSURE BETWEEN TWO REGIONS CAN BE REDUCED AT LOW COST AND WITH LITTLE MAINTENANCE EFFORT WHEN CONTINUOUSLY CONVEYING GRANULAR SOLIDS, A GASEOUS MEDIUM (9) IS INJECTED INTO A TUBE THROUGH AN UPWARDLY DIRECTED NOZZLE (6) AT THE POINT WHERE THE GRANULAR SOLIDS ARE CONVEYED THROUGH A DESCENDING LINE (2) INTO AN ASCENDING LINE (3).FIGURE 1

Abstract: The present invention relates to a method and a plant for the heat treatment of solids containing titanium and possibly further metal oxides, in which fi ne- grained solids are heated to a temperature of 700 to 950 ~C in a fluidized b ed reactor (1). To improve the energy utilization, it is proposed to introduce a first gas or gas mixture from below through a gas supply tube (3) into a mixing chamber (7) of the reactor (1), the gas supply tube (3) being at leas t partly surrounded by a stationary annular fluidized bed (10) which is fluidized by supplying fluidizing gas. The gas velocities of the first gas o r gas mixture as well as of the fluidizing gas for the annular fluidized bed (10) are adjusted such that the particle Froude numbers in the gas supply tu be (3) are between 1 and 100, in the annular fluidized bed (10) between 0.02 an d 2 and in the mixing chamber (7) between 0.3 and 30.

Abstract: A process of continuously conveying granular solids from a first zone with a pressure of 4 to 16 bar through a descending line and via an ascending line to a second zone with a pressure which is lower than in the first zone by 3 to 15 bar, by means of a gaseous medium. To ensure that the pressure between two regions can be reduced at low cost and with little maintenance effort when continuously conveying granular solids, a gaseous medium is injected into a tube through an upwardly directed nozzle at the point where the granular solids are conveyed through a descending line into an ascending line.

Abstract: The present invention relates to a method and a plant for the heat treatment of solids containing titanium and possibly further metal oxides, in which fine-grained solids are heated to a temperature of 700 to 950 ~C in a fluidized bed reactor (1). To improve the energy utilization, it is proposed to introduce a first gas or gas mixture from below through a gas supply tube (3) into a mixing chamber (7) of the reactor (1), the gas supply tube (3) being at least partly surrounded by a stationary annular fluidized bed (10) which is fluidized by supplying fluidizing gas. The gas velocities of the first gas or gas mixture as well as of the fluidizing gas for the annular fluidized bed (10) are adjusted such that the particle Froude numbers in the gas supply tube (3) are between 1 and 100, in the annular fluidized bed (10) between 0.02 and 2 and in the mixing chamber (7) between 0.3 and 30.

Abstract: This invention relates to a process and a plant for the heat treatment of solids containing titanium. For this purpose, the fine-grained solids are heated to a temperature of 700 to 1000°C in a reactor (4) with circulating fluidized bed and are partly discharged from the reactor (4) together with waste gases into a downstream separator (9). In the same, the solids are separated from the waste gases and are recirculated to the reactor (4) at least partly and/or phase by phase. According to the invention, the heat treatment is performed under oxidizing conditions.
