Solubility of Carbonyl Sulfide in Aqueous Solutions of Ethylene Glycol at Temperatures from (308.15 K to 323.15) K

Solubility data were measured for carbonyl sulfide (COS) in the binary system of ethylene glycol (EG) + water at (308.15, 313.15, 318.15, and 323.15) K. Measurements were carried out by a saturation method using a glass equilibrium cell, which was controlled at constant temperatures by a thermostati...

Description
Summary:Solubility data were measured for carbonyl sulfide (COS) in the binary system of ethylene glycol (EG) + water at (308.15, 313.15, 318.15, and 323.15) K. Measurements were carried out by a saturation method using a glass equilibrium cell, which was controlled at constant temperatures by a thermostatic bath with a Beckmann thermometer. The solubility data were obtained with uncertainties within ± 0.02 K for temperature and ± 0.133 kPa for system pressure, and the solubility data of COS in various ethylene glycol−water solutions (EGWs) were obtained with a maximum errorr with 3.88 %. Using the calculated method, the solubility of COS is acquired in various EGWs at the same temperatures and 0.10132 MPa. The results of this work can be used to provide important solubility data for the design and operation of the absorption process for COS with potential industrial application of various EGWs.
