ABSTRACT:
A body of particles of sodium chloride (1) initially containing sodium sulfate and/or sodium carbonate, and/or (2) exposed to compounds capable of reacting in situ with the sodium chloride and/or with each other to form sodium sulfate and/or sodium carbonate, is maintained free from caking at temperatures within the range of from about 610.degree. C to at least about 700.degree. C by maintaining such a body substantially free from sodium sulfate and/or sodium carbonate. One or more compounds, at least one of which contains calcium ion, are provided in the system to react with any sodium sulfate and sodium carbonate present in the system initially, and with any compounds in the system which would otherwise react to form sodium sulfate and/or sodium carbonate. One aspect of this invention enables the operation of a fluidized bed reactor at more efficient operating temperatures than previously attainable in the incineration of organic matter contained in an aqueous sodium chloride brine over a bed of sodium chloride fluidized by gases from the combustion of sulfur-containing fossil fuels and fuel oils.
