Injector assembly, chemical reactor and chemical process

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...
