    摘要: An apparatus and method is provided for the production of alkali metals and caustic solutions. The apparatus and method do not require the use of toxic liquid mercury-sodium amalgam electrodes. The apparatus and methods utilize a bismuth-indium-tin eutectic alloy as a substitute for the mercury electrode used in a conventional Castner-Kellner apparatus.

    摘要: In an alkali salt electrolysis operation by the mercury process wherein mercury recovered in a denuding tower is recirculated with wash water through a mercury return passageway to be returned to an electrolytic cell, a portion of the mercury is caused to constantly overflow together with washing water over a weir provided in the mercury return passageway and then to undergo auxiliary circulation to a mercury reservoir interposed between the denuding tower and a mercury pump. An alkali chloride electrolytic apparatus, in which a reservoir tank is provided between a denuding tower and a mercury pump and an auxiliary circulation passageway communicates between a mercury return passageway and an entrance of the reservoir tank.
