CHEMICAL-SEPARATION PROCESS FOR HIGHLY SALINE WATER .1. PARAMETRIC EXPERIMENTAL INVESTIGATION

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.
