GAS-HYDRATE FEEDING METHOD TO PRESSURE GASIFICATION TANK

摘要

PROBLEM TO BE SOLVED: To provide an energy saving type pellet supplying method which does not need a compressor to boost the pressure of a low pressure gas.

SOLUTION: The energy saving type pellet supplying method is a method to supply the gas-hydrate and water after mixing with a mixer to the high pressure gasification tank. The method comprises a charging step (1) of supplying the gas-hydrate (a) to the mixer 18 under normal pressure, a pressurized water injection step (2) of generating swirling flow by supplying the pressurized water w' from the high pressure gasification tank 17 to a swirling chamber 34 in the mixer, swirling the gas-hydrate in an agitation turbulance chamber 33 under the swirling chamber which rides on the swirling flow and compressing the gas g generated in the mixer by utilizing the elevation of the water level, a discharging step (3) of supplying a mixed matter b of the gas-hydrate and the pressurized water which is swirling in the agitation discharging chamber and a water injection degassing step (4) of introducing the high pressure gas g' collected at the upper part of the mixer utilizing the pressurized water from the high pressure gasification tank after withdrawing the gas-hydrate in the mixer into the high pressure gasification tank.
