Abstract: The device comprises a first reactor (10) with a jacket (100), which limits a reactor chamber of the first reactor for receiving a separated gas mixture, a device for grinding substances present in the reactor chamber, and balls by which the reactor chamber is directed in counter-current to that of the gas mixture along a movement direction. The balls form a sphere packing, where the balls take away the substances along the movement direction through the reactor space so that the substances come between the balls and are crushed by the balls. The jacket extends along its longitudinal axis. The device comprises a first reactor (10) with a jacket (100), which limits a reactor chamber of the first reactor for receiving a separated gas mixture, a device for grinding substances present in the reactor chamber, and balls by which the reactor chamber is directed in counter-current to that of the gas mixture along a movement direction. The balls form a sphere packing, where the balls take away the substances along the movement direction through the reactor space so that the substances come between the balls and are crushed by the balls. The jacket extends along its longitudinal axis, where the longitudinal axis coincides with the vertical and the movement direction is downwardly directed along the vertical. The first reactor comprises a head (11), which faces a sump (12) of the first reactor along the longitudinal axis. A first inlet for the insertion of balls in the reactor chamber is provided at the head, and a first outlet for discharging the balls from the reactor space is provided at the sump. The first outlet limiting an edge area of the first reactor is formed in funnel-shape. Longitudinally stretched elements (30) are arranged in the reactor chamber transversely to the movement direction, and comprise two successive sides that form an edge facing one of the first inlets of the first reactor. The device further comprises: a first conveyor in the form of a screw arranged in the reactor chamber for transporting the balls along the movement direction; a separate second reactor for producing a gas hydrate water mixture from the first gas and water; a column associated with the first outlet of the first reactor; a second conveyor; and a cooling apparatus for cooling the balls. A second inlet is provided at the jacket for guiding the gaseous mixture to be separated in the reactor chamber, where the second inlet is formed on the jacket in the middle third. The first reactor provides water on the balls so that the material consisting of a gas hydrate formed from a first gas of the gas mixture and water accumulates at the beads, and further comprises a planned third inlet at the head in the form of a nozzle arranged in the reactor chamber for providing water on the balls. The second reactor is connected with the head of the first reactor for pressurizing the balls with the gas hydrate water mixture over a third inlet of the first reactor. The balls are promoted into the column from the reactor chamber via a first inlet of the column. The column comprises a further head having a first outlet via which the first gas is removable from the column and a second outlet via which water is removable from the column. The second outlet of the column is connected with the reactor chamber for loading the balls with water through the third inlet of the first reactor and for cooling water through a heat exchanger. An outlet for withdrawing a gaseous phase enriched with the second gas is provided at the head of the first reactor. The second conveyor comprises a continuous conveyer such as a bucket elevator and/or a screw. The cooling apparatus is formed by a heat exchanger.
