    摘要: This invention relates to the methods and installations for producing ultra pure sodium chloride salt crystals primarily for use in saturating depleted brine resulting from the electrolytic decomposition of saturated brine in chlor alkali membrane cells for the production of chlorine, caustic soda and hydrogen. More particularly, this invention related to the production of ultra pure sodium chloride salt crystals by processing primary treated brine by first acidifying the primary treated brine, then stripping the carbonic acid produced by acidification as carbon dioxide, and then returning the brine to a pH of about 6 or higher which is sufficient for processing it in evaporation equipment where the ultra pure salt crystals are produced.

    摘要: A process for recovering mercury from a mercury-containing gas which includes mixing chlorine with the gas, then passing the mixture through a gas-permeable bed of a non-porous solid material which has a large surface area in relation to the bed volume to collect necessary chloride thereon and thereafter recovering the mercury by either washing the bed with chlorine containing brine and passing the resulting mercury-containing brine to an electrolysis cell with a mercury cathode or dissolving the bed material in an aqueous process stream and passing the stream to an electrolysis cell with a mercury cathode.
