Experimental data are presented for the liquid‐liquid‐vapour (LLV) equilibrium for the system water‐hydrogen sulphide. Conditions ranged from the hydrate‐liquid‐liquid‐vapour quadruple point (29.4°C and 2.23 MPa) to beyond the critical temperature of hydrogen sulphide (100.3°C). The maximum temperature at which three phases can exist is 106.2°C at 9.39 MPa. This is 6°C higher than previously believed.
