    摘要: The operation of a plant for producing a gas hydrate is stabilized by making the gas phase within a downstream step have the same equilibrium composition as that of the gas phase within a generation step. The gas phase within a mixed-gas hydrate generation step is circulated to the gas phase within a downstream step located downstream of the mixed-gas hydrate generation step, and the gas phase within each step is thereby made to have the same equilibrium composition as that of the gas phase within the generation step.

    摘要: The disclosure provides an LS methane hydrate containing a plurality of methane hydrate crystals and lignosulfonate. The disclosure also provides a method of making an LS methane hydrate by combining methane gas, liquid or solid water, and LS at controlled temperature and starting pressure for a time sufficient to form LS methane hydrate. The disclosure further provides a method of producing energy from an LS methane hydrate by providing an LS methane hydrate directly to a combustion chamber, whereby methane in the methane hydrate and LS are converted to energy in the combustion chamber and water in the methane hydrate is converted to steam. The disclosure additionally provides a method of releasing methane from an LS methane hydrate by heating an LS methane hydrate.

    摘要: A method is for molding a gas hydrate pellet for improving convenience of handling of a natural gas hydrate during transportation and storage, and thereby improving the practical use of the natural gas hydrate. Gas hydrate slurry is fed in a compression chamber, and pressure and compression are applied to the gas hydrate slurry by advancing a compression plunger. At that time, a stroking speed of the compression plunger is set minimum, preferably less than a value expressed by a stroke length of the compression plunger at compression×10−2 (m/min). By advancing the compression plunger at low speed, binding between particles of the gas hydrate is tightened, thereby the gas hydrate pellet with increased shearing strength can be molded.
