Particle based electrodes and methods of making same

A high capacity chlorine dioxide gas generator includes an anolyte loop for generating chlorine dioxide gas and a cooling system connected to said anolyte loop. A chlorine dioxide solution generator includes a chlorine dioxide gas source, an absorption loop fluidly connected to the chlorine dioxide gas source for effecting the dissolution of chlorine dioxide into a liquid stream, and a cooling system that functions in the chlorine dioxide gas source or the absorption loop. A method of generating chlorine dioxide solution includes providing a chlorine dioxide gas source, dissolving chlorine dioxide into a liquid stream using an absorption loop fluidly connected to the chlorine dioxide gas source, and cooling the chlorine dioxide in at least one of the chlorine dioxide gas source and the absorption loop.

High-capacity chlorine dioxide generator

A chlorine dioxide solution generator includes a chlorine dioxide gas source. An eductor system is fluidly connected to the chlorine dioxide gas source for at least partially effecting the dissolution of chlorine dioxide gas into an aqueous liquid stream. An absorption system is fluidly connected to the eductor system that is capable of effecting additional dissolution of the chlorine dioxide gas into said aqueous liquid.

Chlorine dioxide solution generator

A chlorine dioxide solution generator includes a chlorine dioxide gas source and an absorption loop for effecting the dissolution of chlorine dioxide into a liquid stream. A gas transfer assembly is interposed between the chlorine dioxide gas source and the absorption loop. The gas transfer assembly includes a gas transfer pump and an exhaust manifold assembly. The exhaust manifold assembly includes a manifold conduit defining an interior volume for directing the pressurized chlorine dioxide gas stream from the pump outlet to the absorption loop. The manifold conduit interior volume is sufficiently large to inhibit chlorine dioxide decomposition in the pressurized chlorine dioxide gas stream by induce a pressurized chlorine dioxide gas stream temperature within the manifold conduit of less than about 163&#xb0; F. (73&#xb0; C.).

Chlorine dioxide solution generator with temperature control capability

A chlorine dioxide solution generator, which injects a chlorine dioxide solution into a pressurized fluid system, including an absorption loop for effecting the dissolution of chlorine dioxide into a liquid stream. The chlorine dioxide gas source can include an anolyte loop and a catholyte loop. The generator avoids or eliminates the introduction of air or other gases that can cause corrosion in the process distribution system.

A long life double layer capacitor and method of making the same including a case and a first terminal with an electrically insulating hermitic seal interposed between the first terminal and the case. A first current collector foil is electrically coupled to an interior portion of the first terminal and a first electrode comprising carbon which is juxtaposed against the first current collector foil. A porous separator is then juxtaposed against the first electrode comprising carbon and separating the first electrode from a second electrode comprising carbon. A second current collector foil is juxtaposed against a side of the second electrode and is electrically coupled to the second terminal. And an electrolyte solution saturates the first and second electrodes comprising carbon and is substantially contained by the case and the electrically insulating hermitic seal such that an influx of impurities into the electrolyte solution is substantially inhibited by the case and the electrically insulating hermetic seal.
