摘要： A side stream subsystem can be used to remove impurity species from the recirculating alkali metal chloride solution in certain electrolysis systems. Silicon and/or aluminum species can be removed via precipitation after introducing an alkali metal hydroxide and magnesium chloride in a side stream line in the subsystem. The invention can allow for a substantial reduction in raw material and capital costs.

摘要： An electrolytic cell producing sodium chlorate uses an electrode, specifically an anode, having a coating of a mixed metal oxide having ruthenium oxide as an electrocatalyst, a precious metal of the platinum group or its oxide as a stability enhancer, antimony oxide as an oxygen suppressant and a titanium oxide binder. The electrocatalytic coating is about 21 mole percent ruthenium oxide, about 2 mole percent iridium oxide, about 4 mole percent antimony oxide and the balance is titanium oxide. The coating is characterized by high durability and low oxygen content in an offgas.

摘要： By-product hypochlorite from the electrolytic production of chlorates, notably sodium chlorate, is used to form hexavalent chromium for use in the electrolysis process by oxidation of trivalent chromium compounds by the hypochlorite. The hypochlorite may be the condensate produced by treatment of the chlorate cell by-product gas stream and/or present in the cell liquor.

摘要： The present invention relates to process to prepare a chlorine-containing compound using an aqueous salt solution containing at least 100 g/l of sodium chloride and a contaminating amount of polyvalent cations comprising the steps of (i) preparing an aqueous salt solution containing at least 100 g/l of sodium chloride and at least 0.01 ppm of polyvalent cations by dissolving a sodium chloride source in water, (ii) adding an effective amount of at least one positive retention enhancing component to the aqueous solution, (iii) subsequently subjecting the solution to a nanofiltration step, thereby separating the solution into a retentate which is enriched for polyvalent cations and a permeate which is the purified aqueous salt solution, (iv) reacting the chloride anions in the permeate to a chlorine-containing compound by an electrolysis step, and (v) recycling at least part of the retentate to dissolution step (i).

摘要： A gas diffusion electrode for an electro-synthetic or electro-energy cell, for example a fuel cell, including one or more gas permeable layers, a first conductive layer provided on a first side of the gas diffusion electrode, and a second layer, which may be a second conductive layer, provided on a second side of the gas diffusion electrode. The one or more gas permeable layers are positioned between the first conductive layer and the second layer, which may be a second conductive layer, and the one or more gas permeable layers provide a gas channel. The one or more gas permeable layers are gas permeable and substantially impermeable to the liquid electrolyte. The porous conductive material is gas permeable and liquid electrolyte permeable. The gas diffusion electrode can be one of a plurality of alternating anode/cathode sets.
