Raw data of methane hydrate equilibrium measurements in the systems of CH4 – H2O – THI and hydrate nucleation/growth in the systems of CH4 – H2O – KHI – THI

The raw data of Part 1 of the work devoted to the study of the methane hydrate equilibrium conditions in the systems of CH4 – H2O and CH4 – H2O – THI (THI = MeOH, MEG, DEG) are given in the “CH4 hydrate equilibrium measurements” archive. Each file with the .xlsx extension corresponds to data obtained from a single equilibrium point measurement and includes columns for time, temperature (°C), and gauge pressure (bar) in the GHA350 autoclave. The file name represents the system under study and the point number for it. For example, the file name “30% DEG_point 4” corresponds to the raw data obtained from measurements of the fourth equilibrium point for a 30 mass% aqueous solution of diethylene glycol. Each file contains the masses of the components taken to prepare an aqueous solution and their concentrations in mass%.
The raw data presented in the archive “CH4 hydrate nucleation&growth” are from Part 2 related to the study of the kinetics of methane hydrate formation in the systems of CH4 – H2O, CH4 – H2O – KHI, and CH4 – H2O – KHI – THI (KHI = copolymer of N-vinylpyrrolidone and N-vinylcaprolactam). Each file with the .xlsx extension contains data obtained in one of the cooling-heating cycles for a specific inhibitor sample. The data in the file includes time (since the start of the cycle), thermostatic bath temperature (°C), and gauge pressure (bar) for each of the six test cells of the RCS6 setup. The file name corresponds to the test sample and the cooling-heating cycle number for it. For example, the file name “0.5%KHI+10% MeOH_1 cycle” corresponds to the raw data obtained in the first cooling-heating cycle for a sample containing 0.5 mass% kinetic inhibitor and 10 mass% methanol in water. Each file contains the exact values of the masses and concentrations of the components.
