Raw data of gas hydrate equilibria and PXRD measurements in system C3H8/CH4 – H2O – Urea
No full textThe raw data from the measurements of the gas hydrate equilibrium conditions in the methane/propane-water-urea system are given in the “Hydrate equilibrium (C3H8+CH4-Urea-H2O)” archive. A model gas mixture of 4.34% C3H8 + 95.66% CH4 (mol%) was used as a hydrate-forming gas. A total of 39 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 sample under study and the point number. For example, the file name “30% Urea_point 24” corresponds to the raw data obtained from measurements of the 24th equilibrium point (numbering from Table 1 of data paper [2]) for a 30 mass% aqueous solution of urea. Cells D1:H3 of each file (except for 0% Urea sample) display numerical values of the masses and concentrations of urea and water in the aqueous phase.The raw data presented in the archive “PXRD analysis (C3H8+CH4-Urea-H2O)” are related to the powder X-ray diffraction study of the phase composition of gas hydrate samples synthesized from urea aqueous solutions. Diffractograms were recorded for 5 samples. Two of them were recorded for the samples obtained from 20 mass% aqueous urea solution (samples 1 and 2). For samples 1 and 2, the pressure of the hydrate-forming gas during the synthesis was 1.5 and 6 MPa, respectively. Two diffractograms were acquired for the samples obtained from 40 mass% urea solution (samples 3 and 4). For samples 3 and 4, the gas pressure during hydrate synthesis was 1.5 and 6 MPa, respectively. One diffractogram was obtained for a frozen 40 mass% urea solution (sample 5) without methane/propane hydrates. For each sample, a separate file containing numerical values of 2θ (degree) and signal intensity (a.u.) is provided.The raw data is linked to the papers:[1] Yinghua Gong, Rais I.
