Device for producing gas hydrate

Abstract

FIELD: physical processes.SUBSTANCE: invention relates to devices for mixing gases with liquids and can be used to obtain gas hydrate. A device to obtain gas hydrate comprises a reactor in the form of a cup with a cooling jacket, which is connected to a thermostat by two pipelines, a temperature sensor mounted in the side wall of the reactor, a gas cylinder connected by a pipeline comprising a flow meter to the reactor cavity. The reactor's cooling jacket is fitted with fittings for the coolant inlet and outlet, which are connected by pipelines to the thermostat. A hollow cylinder, the height of which is less than the height of the cup, is welded to the upper surface connecting the edges of the cup and the cooling jacket. The outer diameter of the hollow cylinder is smaller than the outer diameter of the cup. The inner diameter of the hollow cylinder is larger than the inner diameter of the cup. The inner surface of the hollow cylinder wall is threaded. A shaft in the form of a solid metal cylinder with a larger diameter protrusion at one end is inserted into the hollow cylinder from above, which is located on the surface connecting the edges of the cup and the cooling jacket. A rubber ring, a metal washer and a sleeve are successively placed on the shaft until it stops with a protrusion of a larger diameter. The upper part of the sleeve is made with an annular protrusion, under which a thread is made on its outer surface for connection with the thread on the inner surface of the wall of the hollow cylinder. Inside the shaft, along its axis, a channel is made through which a metal pipe is inserted into the cup, one end of which, placed in the cup, is plugged, and in its lower part along the circumference at an equal distance from each other, four holes are made into which nozzles are mounted, directed upward at an angle of 45° relative to the bottom of the cup. The end of the pipe protruding from the top of the shaft is equipped with the first valve and is connected by a pipeline to one end of the coil located in the thermostat bath. The other end of the coil is connected by a pipeline equipped with the first pump to a tank filled with water. At the bottom of the cup there is a drain hole covered with a grate. The drain hole is connected to the other end of the coil by a pipeline equipped with a second tap, a second pump and a third tap. A pipeline comprising the first pressure relief valve is brought out from the cavity of the cup. The cavity of the cup is connected to a gas cylinder by a pipeline comprising a second valve and a flow meter. A pressure sensor is built into the wall of the cup. A flow meter, a temperature sensor and a pressure sensor are connected to the personal computer. The gas cylinder is filled with either methane, ethane, propane, or carbon dioxide.EFFECT: obtaining a gas hydrate with a density of 600-700 kg / m3 and gas saturation of up to 150-160 volumes of gas per 1 volume of hydrate.2 cl, 5 dwg
