Abstract:
A reaction cell system for measurement of catalyst demand, comprising:a reaction cell having a spherical chamber therein, said chamber having an inlet and an outlet, said inlet and outlet being substantially diametrically opposed;a source of fluid connected to said inlet through an inlet valve;a return line connected to said outlet through an outlet valve;an optical cylinder traversing said chamber centrally thereof and interposed between said inlet and outlet;a source of catalyst in communication with a catalyst dispenser;a source of indicator in communication with an indicator dispenser;a catalyst injector within said spherical chamber and in operative communication with said catalyst dispenser;an indicator injector within said spherical chamber and in operative communication with said indicator dispenser;an agitator maintained in a lower portion of said spherical chamber, beneath said optical cylinder, said agitator mixing the fluid, the catalyst and the indicator within said spherical chamber to generate a uniform flow of mixed material observable by said optical cylinder, anda valve network interposed between said sources of indicator and catalyst, said indicator and catalyst dispensers, and indicator and catalyst injectors to regulate a transfer of precise volumes of indicator and catalyst into said spherical chamber.
