摘要： The present invention relates to a method for producing a metal by a direct oxide reduction process with Ca. A CaCl2-based molten salt containing Ca is held in a reduction chamber 1, a metal oxide is introduced into the molten salt in the reduction chamber 1, and the metal oxide is reduced with the Ca in the molten salt to form said metal. The metal formed in the molten salt is separated from the molten salt in a separation means 2, and the molten salt deprived of the metal is introduced into a chlorination chamber 7 and subjected to chlorination treatment with chlorine gas to eliminate the byproduct CaO in the molten salt. The molten salt after chlorination treatment is introduced into an electrolysis chamber 8 and electrolyzed for the formation of Ca and chlorine from CaCl2, and the thus-formed Ca or Ca-containing molten salt is transferred from the electrolysis chamber 8 to the reduction chamber 1. The chlorine obtained in the electrolysis chamber 8 is used in the chlorination chamber 7. Thus, the present invention provides a metal production method and an apparatus wherein high levels of productivity are obtained and the product metal can be inhibited from carbon contamination due to CaO, without any generation of CO2 from the production process, while their being based on the direct oxide reduction process comprising the step of reducing a metal oxide with Ca.

摘要： In a method for producing sodium hypochlorite, brine solution is piped from the brine tank to a first inlet in a first electrolyzer cell of an electrolyzer assembly while simultaneously piping chilled water from a chiller having a temperature range from about 10° C. to about 25° C. to the first inlet so that the brine solution combines with the chilled water. The chilled brine solution is electrolyzed in the first electrolyzer cell. The hypochlorite and brine solution resulting from electrolysis occurring in the first cell is piped to a second inlet in a second electrolyzer cell in the electrolyzer assembly while simultaneously piping chilled water from the chiller having a temperature range from about 10° C. to about 25° C. to the second inlet so that the chilled water combines with the hypochlorite and brine solution. Each cell can have more than one inlet, preferably up to 6 inlets. The chilled hypochlorite and brine solution are electrolyzed in the second cell. The process is repeated until the hypochlorite and brine solution passes through all cells of the electrolyzer assembly.
