Gas hydro rate pelleting device and gas hydro rate pelleting method

摘要

Provided are a gas hydrate pellet molding device and a gas hydrate pellet molding method that make it possible to improve efficiency in molding GH pellets by performing a gas hydrate dehydration process and a GH pellet molding process with a single device. The inside of an inner barrel (3) comprising a porous plate is divided by a die plate (4) into a compression chamber (5) and a pellet accommodation chamber (6). A compression plunger (7) and a die opening and closing plunger (9) are slidably disposed in the compression chamber (5) and the pellet accommodation chamber (6), respectively. The die opening and closing plunger (9) is pressed against the die plate (4) to close the die plate (4), and the compression plunger (7) is moved forward to compress and squeeze the water out from a GH slurry supplied to the compression chamber (5). Discharged water flows to a water draining chamber (3a) through a through-hole of the inner barrel (3). The die plate (4) is opened and the compression plunger (7) is moved further forward to push the GH slurry out of the die plate (4), so as to form a GH pellet and then the GH pellet is transferred to the next process by means of a conveyance means.
