摘要:
In this invention, a novel process for saline waters and saline solutions conversion has been provided that requires only a fair amount of a miscible organic solvent and heat transfer. Such requirements are ordinary in the nature of precipitation and vaporization. The invented process consists of adding a miscible (strongly associated) organic solvent to saline water so that salt precipitates of the saline water is formed. The resultant salt precipitates (pure solids) is then separated from the organic-water mixture. After separating the salt precipitates, the miscible organic solvent is removed and recovered from the organic-water mixture by applying vacuum with or without heating, or by using distillation methods. The separated miscible organic solvent can then be condensed and returned to the process and water is stripped of trace of miscible organic solvent, and removed from the system as product water. The invented process is potentially suited for the precipitation and separation of salts, scale salts, and NORM contaminant salts form saline water and saline solution as well as for the remediation of contaminated soils.
摘要:
A process for the precipitation and separation of inorganic species form aqueous solutions. The method comprises the step of adding a miscible organic solvent to inorganic-aqueous solution so that a solid precipitate from the aqueous solution is formed. The resultant solid precipitate is separated from the organic-water mixture. After separating the solid precipitate, the miscible organic solvent is removed and recovered from the organic-water mixture by applying vacuum or other means of recovery. The separated miscible organic solvent can then be condensed and returned to the process. The water is stripped of traces of miscible organic solvent and removed from the system as product water.
