摘要： A sodium sulfite liquor is formed by reacting sodium carbonate with sulfur dioxide. A CO2 byproduct may be removed from the formed liquor by injecting a stripping gas (e.g., steam and/or air) into the liquor, either into a transfer pipe or into a tank that is vented; by increasing the liquor temperature; and/or by reducing the liquor pressure. The decarbonated sodium sulfite liquor with a reduced carbon dioxide content is introduced into a crystallizer connected to a circulation loop comprising a heater and/or a filter. Additional decarbonation by heating, stripping and/or depressurization of the liquor may be carried out in a circulation loop connected to the crystallizer. The condensing side of the heater may be vented. The flow rate of the circulation loop and/or heater temperature differences may be monitored. Additional CO2 may be vented from a holding tank to maintain circulation loop flows and heater temperature differences.

摘要： The present invention relates to recovery of industrial grade potassium chloride and low sodium edible salt from bittern as part of an integrated process. The process comprises, mixing low sulphate concentrated feed bittern (a by-product of salt industry) of density 31.5 to 32.5° Be (sp.gr. 1.277-1.289) with high density end bittern of density 36.5 to 37.5° Be′ (sp.gr. 1.336-1.35), thereby producing low sodium carnallite, from which industrial grade potassium chloride is produced. The resultant bittern is evaporated in forced evaporation system, thereby producing crude carnallite, from which low sodium salt that would be beneficial to persons suffering from hypertension is produced. When sulphate-rich bittern is used, such bittern is desulphated with CaCl2 that is generated from carnallite decomposed liquor through reaction with lime, and wherein low B2O3-containing Mg(OH)2 is a by-product. The entire content of potassium in feed bittern is recovered in the process of the invention.

摘要： A process for recovering alkali values from trona ore by partially dissolving trona in a first dissolving solution to form a first feed liquor and undissolved trona. The first feed liquor is cooled and sodium carbonate decahydrate is precipitated. The sodium carbonate decahydrate is recovered from the resultant first mother liquor that is returned as the first dissolving solution. The undissolved trona is further dissolved in a second dissolving solution to form a second feed liquor. The second feed liquor is preferably carbonated to convert sodium carbonate into sodium bicarbonate, and cooled to precipitate sodium bicarbonate. The sodium bicarbonate is recovered from the resultant second mother liquor that is returned as the second dissolving solution.

摘要： A system for extracting sodium, particularly radioactive .sup.22 Na, from aluminum utilizes a monel exhaust system for exhausting sodium vapor emitted from a molten aluminum target, in a draft of helium gas. The aluminum target is heated until it is melted in a graphite support cup. The graphite support does not react with the sodium. Moreover, the graphite is understood to be permeable to the helium gas, its porosity being believed to provide the significant advantage that the graphite holder will not absorb much of the sodium vapor. The use of graphite avoids a disadvantageous monel-aluminum reaction whereby an alloy from which sodium cannot be distilled is formed. The resulting sodium vapor is precipitated in a monel exhaust tube which is subjected to temperature control. Sodium can be rinsed from the monel exhaust tube with water.
