    摘要： An onsite integrated production factory having an electrolytic plant, an ethanol plant, a vegetable plant, a culturing plant, and a power generation unit. The onsite integrated production facility is arranged so that fresh water, sulfuric acid or caustic soda produced by and received from the electrolytic plant is used in the ethanol plant to produce and output oxalic acid, sodium oxalate, fuel bioethanol. The oxalic acid or sodium oxalate produced in and received from the ethanol plant is used for removing calcium contained in the sea water in the electrolytic plant. The vegetable plant produces vegetables for generation and outputting of oxygen by receiving the carbon dioxide generated during the fermentation process in the ethanol plant and fresh water from the electrolytic plant. The culturing plant has a fishery farm or reef for using the oxygen generated in the vegetable plant.

    摘要： A method for electrochemically purifying solutions with a pH higher than 14 to reduce metal impurities to the level of traces. The method comprises processing the solutions in an electrolytic cell in which the cathode has a fibrous web produced from a mixture of fibres including at least one fraction consisting of electrically conductive fibres and a binder selected from fluoropolymers, said fibrous web being deposited on an electrically conductive porous support. Said cathode may also be combined with a diaphragm or a membrane. A cathode having a fibrous web produced from a mixture of carbon fibres, cellulose compounds, and a cationic polymer such as cationic starch is also disclosed.

    摘要： An electrolytic process is described for purifying an aqueous solution of an alkali metal hydroxide containing an impurity of a soluble heavy metal complex comprised of a heavy metal cation and a plurality of anions.For example, an aqueous solution of sodium hydroxide containing a soluble heavy metal complex, such as mercuric polysulfide, [HgS].sup.+ S.sup.-, is charged to the electrolytic chamber of an electrolytic cell. An electric current is employed to reduce heavy metal cations to a separate phase in elemental form, and simultaneously to oxidize anions to a separate phase in elemental form, and to form a slurry of the separate phases in elemental forms in the aqueous solution.The slurry is removed from the electrolytic chamber and the phases of elemental forms are separated from the purified aqueous solution. The purified alkali metal hydroxide solution is sold commercially or otherwise utilized.

    摘要： A method for concentrating an aqueous caustic alkali produced by a membrane cell process by using a single or multiple effect evaporator system in which the vapor flows in a counter direction to the aqueous caustic alkali flow and the heat recovered from the catholyte circulation line is used as part of the concentration process. In one embodiment, a catholyte heat recovery heat exchanger and flash evaporation chamber are located after the last effect of a multiple effect evaporator system. In another embodiment, the catholyte heat recovery heat exchanger and flash evaporation chamber are located prior to the single or multiple effect evaporator system. In yet another embodiment, the catholyte heat recovery process is used in conjunction with additional heat exchanger processes to further concentrate the final product as desired.
