FIELD: gas industry. ^ SUBSTANCE: compressed and cooled gas is fed to reaction reservoir filled with water and kept at static pressure at temperature below equilibrium temperature of forming hydrate at this static pressure. Gas pressure slightly exceeds pressure in reaction reservoir and temperature of gas is equal to temperature of water contained in reservoir. Gas is mixed with water and pressure shock waves are generated in gas-and-liquid medium at amplitudes of hundreds of atmospheres. Shock waves may be generated by electromagnetic pulse radiators, air hammers or other devices. When shock waves propagate in gas-and-liquid medium, pressure increases due to its weak dissipation and gas phase is crushed in entire reaction reservoir, thus increasing degree of meta-stability of medium and number of nucleating centers of gas hydrate and reducing sizes of gas inclusions, increasing interface and rate of gas inclusions in liquid and turbulization of liquid motion. ^ EFFECT: acceleration of mass-exchange process at interface and intensification of hydrating process. ^ 3 cl, 2 dwg |
