APPARATUS AND METHOD FOR PRODUCING GAS HYDRATE BY GAS- LIQUID COUNTERCURRENT SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a gas hydrate production apparatus and its production method which enable efficient formation of a gas hydrate by prolonging the gas-liquid contact time within a formation tank. SOLUTION: The gas hydrate production apparatus 100 for forming a gas hydrate 55 by reacting water 51 with a gas 53 comprises a longitudinal nearly cylindrical formation tank 11 for forming a gas hydrate 55 under a predetermined pressure and at a predetermined temperature, a water supply pump 17 for continuously introducing water from the top of the formation vessel, a gas diffusion mechanism 31 which introduces the gas in the form of bubbles from the lower part of the above formation tank, and a water discharge means 19 to continuously discharge water from the bottom of the formation tank, and the gas hydrate 55 is produced so as to form a water flow countercurrently to the bubbles rising by buoyancy by continuously supplying water 51 into the formation tank 11 and, simultaneously, discharging water.
