Study of the effect of thermobaric conditions on the process of formation of propane hydrate

Results of experimental studies into the dynamics of mass-exchange processes during synthesis of propane hydrate

“…Mass exchange processes slow down considerably after 3 hours and reach the level of diffusion. Then, intense slowdown of mass exchange continues despite the fact that there is overcooling and a sufficient excess pressure [22]. Obviously, as in [23], the film of the formed hydrate sharply slows down the process of subsequent hydrate formation.…”

Research into resonance phenomena in gas-vapor bubbles

“…The mathematical model [17] was accepted as the basis for studying the influence of acoustic oscillations of the resonance frequency on the thermobaric characteristics of a gas-vapor bubble. This model was supplemented with relevant components in the equation (11) for the purpose of taking into account the thermal effect of phase transition processes on the surface of a bubble and gas dissolution.…”

Influence of external factors on the process of hydrates development in laboratory conditions

“…The struggle with hydrates by various methods is also investigated by many scientists, for example, scientists [8], but they remain either very energy-consuming, or environmentally harmful. It should be noted that scientists of the Poltava National Technical Yuri Kondratyuk University (Ukraine) also carried out theoretical studies in this direction [9,10]. In particular, the hydrodynamic regime of a single gas bubble is considered in [9], which is under hydrate formation conditions.…”

In [10], calculations of phase-reversal processes in the liquid surrounding the gas bubble were performed.…”
