A New Method for the Rapid Synthesis of Gas Hydrates for their Storage and Transportation

Abstract

This presents the analysis of the main reasons for a significant decrease in the intensity of diffusion processes during formation of gas hydrates; solutions to this problem are proposed in a new process flow diagram for the continuous synthesis of gas hydrates. The physical processes, occurring at corresponding stages of the process flow are described in detail. In the proposed device, gas hydrate is formed at the boundary of gas bubbles immersed in cooled water. The dynamic effects arising at the bubble boundary contribute to destruction of a forming gas hydrate structure, making it possible to renew the contact surface and ensure efficient heat removal from the reaction zone. The article proposes an assessment technique for the main process parameters of the synthesis of gas hydrates based on the criterion of thermodynamic parameters optimization.

Theoretical Foundations of Gas Hydrate Synthesis Intensification

“…With the hydraulic method of spraying, it is possible to obtain an aerosol with a dispersion of 30 to 500 microns. The dispersion of the aerosol with the pneumatic method of spraying is within 50-200 μm [23]- [26]. Therefore, in further calculations, the droplet range of 30-500 μm is accepted.…”
