✦ Synopsis

Investigations on the thermophysical properties of treated seawater and NaCl, Na2SO4 and MgC12 solutions of various concentrations have been carried out. Density has been investigated at 20-200 °C temperatures and up to 200 bar pressures . The heat conductivity of seawater and solutions of various concentrations was studied at 20-300'C accounting for the solubility and the results analyzed . The viscosity of NaCl solutions was studied by the capillary method at 20-350 °C and to 300 bars. The absolute value of viscosity decreases with increase in temperature, but the relative value increases . Heat capacitance of NaCl solutions investigated at 20-200°C, was found to decrease with increase in concentration . The surface tension of NaCI solutions was studied by the method of two capillaries at 20-200°C .
