The solubility of hydrogen sulphide in water from 0 to 90°C and pressures to 1 MPa

Abstract There exists some controversy about the solubility of hydrogen sulphide in water—notably the effect of pressure on the solubility. This paper reviews the experimental data for this system for temperatures between 0 and 90°C and for pressures up to 1 MPa. A simple model is used to correlate all of the data, including data that had previously been rejected as inaccurate. It is demonstrated that observed deviations from the strict Henry's law can be explained by the non-ideality of the vapour phase. Also, non-idealities in the liquid phase are negligible for the stated range of temperature and pressure.
