Hk. Abdelaal et al., CHEMICAL-SEPARATION PROCESS FOR HIGHLY SALINE WATER .1. PARAMETRIC EXPERIMENTAL INVESTIGATION, Industrial & engineering chemistry research, 35(3), 1996, pp. 799-804
The separation of highly saline waters under various conditions is car
ried out using a nonconventional partial-desalting process. The method
utilizes a series of chemical reactions involving the conversion of s
odium chloride, the major constituent in saline waters, into sodium bi
carbonate, which precipitates under the experimental conditions, anti
ammonium chloride, which can be separated by crystallization. Experime
nts of absorption of carbon dioxide in an ammoniated brine have demons
trated the efficiency of the method. Interpretations using conversion
parameters such as temperature, initial concentrations of ammonia, sod
ium chloride, and the ratio of NH3/NaCl are discussed.
