The raw data from the measurements of the methane hydrate equilibrium conditions in the methane-water-dimethyl sulfoxide system are given in the “Hydrate equilibrium (CH4-DMSO-H2O)” archive. A total of 54 equilibrium points have been measured. For each of them there is a separate .xlsx file in the archive with columns of numerical values of the following parameters measured by sensors of GHA350 autoclave: time, temperature (°C), gauge pressure (bar), stirrer speed (rpm). The file name represents the system under study and the point number. For example, the file name “5% DMSO_point 13” corresponds to the raw data obtained from measurements of the 13th equilibrium point (numbering from Table 1 of data paper [2]) for a 5 mass% aqueous solution of dimethyl sulfoxide. Cells D1:F3 of each file display numerical values of the masses and feed concentrations of the components in the aqueous phase. The raw data presented in the archive “PXRD analysis (CH4-DMSO-H2O)” are related to the powder X-ray diffraction study of ...
