    Abstract: A process for saturating a material capable of binding ammonia by ad- or absorption and initially free of ammonia or partially saturated with ammonia comprises treating said material under a pressure and associated temperature located on the vapor pressure curve of ammonia with an amount of liquid ammonia sufficient to saturate said material and an additional amount of a cooling agent selected from liquid ammonia, liquid or solid CO2, hydrocarbons and hydrohalocarbons that have a higher vapor pressure than ammonia, ethyl ether, methyl formate, methyl amine and ethyl amine, such that |Qabs|≦|Qevap|+Qext, wherein Qabs is the amount of heat released from said material when it absorbs ammonia from the liquid phase thereof to the point where it is saturated with ammonia, Qevap is the amount of heat absorbed by said cooling agent when it evaporates, and Qext is the amount of heat exchanged with the surroundings and is positive, if heat is removed from the process by external cooling, and negative, if heat is added to the process from the surroundings.

    Abstract: A process for the production of calcium bromide from feed brines, particularly from Dead Sea End Brine (EB), is described. The process comprises extracting the feed brine in countercurrent with a composite organic solvent; optionally, purifying the extract to increase the ratio Br:Cl by contacting it with a part of the product; and washing the purified extract with water to yield the product, that is an aqueous solution of CaBr2. The composite solvent comprises an anionic extractant, such as an amine or a mixture of amines; a cationic extractant, such as a carboxylic phosphoric or sulphonic acid or a mixtures of said acids; and diluent/modifier, which is an organic solvent. An apparatus for the production of calcium bromide is also described, which comprises: an extraction battery; optionally, a purification battery; and a washing battery, wherein at least one of the batteries comprises a plurality of stages.

    Abstract: Spent potliner from an aluminum reduction cell is subject to an acid digest and the digest may be adjusted to produce a first gas component comprised of at least one material selected from the group consisting of silicon tetrafluoride, hydrogen fluoride, hydrogen cyanide gas and water vapor, and a slurry component comprised of at least one material selected from the group consisting of carbon, silica, alumina, and sodium, iron, calcium and magnesium compounds. The first gas component is removed from the digester and heated to a temperature sufficiently high to convert said silicon tetrafluoride to fumed silica and hydrogen fluoride. Thereafter, the fumed silica is separated from the hydrogen fluoride to recover fumed silica from spent potliner material.
