Embodiment

[0085] This prophetic example is provided to further illustrate the invention.

[0086] Carrying out the method of the present invention for the production of titanium dioxide as described above and Figure 10 and 11 described in. The chemical reactor 18 of the present invention is used in the process. A preheated oxygen feed 120 and a preheated titanium tetrachloride gas feed 122 are introduced into the first reaction zone 136 of the reactor conduit 16 of the reactor 18 in such a manner that the materials flow along their longitudinal axis 20 as a combined reaction feed 12 Through the reactor pipe 16. The flow rate of mixed reaction mass 12 through reactor conduit 16 was 2.5 kg / sec. The temperature of the mixed reaction mass 12 is 1300 degrees Kelvin. The reactor pipe 16 has a diameter of 125 cm (7 inches).

[0087] Auxiliary oxygen is then added to the second reaction zone 220 via the injector assembly 10 . Syringe assembly 10 includes eight ports 42 equally spaced ar...

Abstract

An injector assembly for injecting an additional component into a component stream flowing through a reactor conduit along the longitudinal axis thereof. A chemical reactor including an injector assembly for injecting an additional component into a moving component stream and a chemical process are also provided. In one embodiment, the chemical process is a process for producing titanium dioxide.

Description

technical field [0001] Chemical reactors comprising extended reactor tubing are well known, such as tubular reactor tubing for receiving reactants and allowing the reactants to mix and react continuously. In such reactors, the reaction mass is initiated and flows along the longitudinal axis of the reactor tube as the reaction proceeds. Reactants and other components can be injected into the moving reaction mass at various points in the reactor tube. The reacted product is separated from other components (often recycled) and recovered. Background technique [0002] Injecting reactants or other components into a moving reaction mass and ensuring adequate mixing of said components with other components in the mass can be difficult, for example, when the mass is moving at relatively high speeds. Injection of components around the perimeter of the moving mass often results in slip flow of the components along the inner wall of the reactor tube. As a result, the components cann...
