The methods of industrial production of gas hydrates are considered, theirproblems are identified, and a list of factors that are decisive for the intensification of massexchange processes is outlined. The prospective use of mass transfer devices with a dynamicinterfacial surface for the synthesis of gas hydrates is substantiated. A mathematical modelof hydrate formation on the surface of a water droplet moving in a gas flow is proposed.Digital solutions for various droplet sizes, velocities, gas pressures, water temperature, gaspermeability of gas hydrate, and dynamics of hydrate formation over time were obtained. Itwas established that the main ways of intensification of the synthesis of gas hydrates are:obtaining smaller water droplets, maintaining the gas temperature at the level of 0 °С,increasing the gas pressure, and increasing the residence time of the droplet in the gasmedium. Approximation formulas for calculating quantitative indicators of the influence ofvarious factors on the formation of methane gas hydrate have been obtained. The analysis ofthe obtained results made it possible to establish promising directions for the optimization ofequipment for the synthesis of gas hydrates
