Features of Freezing Processes of Aqueous Solutions
Journal Title: Современное промышленное и гражданское строительство - Year 2018, Vol 14, Issue 2
Abstract
The freezing processes of next salts solutions were studied: sodium chloride, potassium chloride and calcium chloride and ion transfer of salts to ice. The concentrations of salts were determined by the conductometric method and by the titration of chloride and calcium ions. When desalination of waters of high mineralization by the method of freezing, one cycle of the bulk crystallization process does not ensure the production of fresh water by salinity less than 1 000 mg/dm3. An increase in the concentration of solutions of sodium chloride, potassium chloride and calcium chloride does not affect the distribution of salts between ice and brine, which indicates a loose structure of ice. Reducing the time of freezing leads to a slight increase in the degree of water desalination. The fraction of formed ice for the range of concentrations of initial solutions from 5 to 25 g/dm3 with identical freezing time is longer for solutions of sodium chloride and decreases successively for solutions of potassium chloride and calcium chloride.
