摘要

The article presents the results of the study of the influence of pressure and temperature of the gas-water environment on the process of hydrocarbon gas hydration formation, occurring on its phase interface surface. A mathematical model is proposed to determine the optimum ratios of pressure, gas temperatures, water, and gas bubble sizes in the bubbling, gas ejection, or mixing processes. It was determined that the hydrate formation speed reaches maximum values when the gas medium is heated inside the bubble. After damping of bubble oscillations, the hydration process is supported by heat dissipation into outer layers of the fluid. It was determined that there is a gas temperature range where the hydrate formation speed is maximum. The research findings can be used to optimize various technological processes associated with production of gas hydrates in the industry.
