Density and viscosity of aqueous hydrogen sulfide solutions at pressures to 20 atm

Abstract

The physical properties of aqueous hydrogen sulfide solutions under pressure are of practical importance in the large-scale concentration of deuterium by counter-current extraction of natural water with H/sub 2/S gas, the so-called GS process for heavy water production. In addition, information on these properties may be valuable in pollution abatement design. By virtue of the close chemical relationship between hydrogen sulfide and water, some scientific interest also is attached to the behavior of the solutions. The density and viscosity of water saturated with hydrogen sulfide at temperatures in the range 20/sup 0/ to 40/sup 0/C and pressures up to 20 atm are measured. The density float method and a rolling-ball viscometer, modified to permit pre-equilibration of liquid with gas at pressure, are used. (23 refs.)
