Abstract

A continuous system, process and associated apparatus are disclosed for reacting a gas with a liquid to manufacture a gaseous or liquid product. The preferred system comprises a reactive gas, such as chlorine and an aqueous solution, such as caustic soda, which are continuously combined and reacted under largely superatmospheric pressure and in turbulent cocurrent flow in very compact reactor equipment. Liquid bleach solutions such as aqueous solutions of hypochlorites or hypochlorous acid are among the products of major interest. The main reactor equipment consists of a fluid pressure energized, in-line mixing device followed by a low slip (closely fitted) regenerative turbine pumping unit. The fluid ports in the closely fitted stator elements of said pumping unit should have a radial dimension equal to at least about half that of the vanes. In a liquid ring compressor these ports are located adjacent the lower parts of said vanes while in a turbine pump they are generally adjacent the mid portion of said vanes.
