Abstract
Provided is a process and an apparatus for producing at low cost gas hydrate pellets having an excellent storability. A gas hydrate generated from a raw-material gas and raw-material water is dewatered and simultaneously molded into pellets with compression-molding means under conditions suitable for generating the gas hydrate while the gas hydrate is generated from the raw-material gas and the raw-material water that exist among particles of the gas hydrate.

A process for producing gas hydrate pellets, in which a gas hydrate generated from a raw-material gas and raw-material water is dewatered and simultaneously molded into pellets with compression-molding means under conditions suitable for generating the gas hydrate while the gas hydrate is generated from the raw-material gas and the raw-material water that exist among particles of the gas hydrate.
A process for producing gas hydrate pellets, wherein a gas hydrate having a gas hydrate concentration of 40 to 70% by weight is dewatered and simultaneously compression-molded into pellets with compression-molding means under conditions suitable for generating the gas hydrate.
An apparatus for producing gas hydrate pellets that produces gas hydrate pellets by compression-molding a gas hydrate,
- the apparatus for producing gas hydrate pellets, comprising:
- a pair of compression rolls each having a plurality of molds in an outer peripheral surface thereof, the pair of compression rolls rotating respectively in opposite directions to each other;
- and
- feeding means for feeding the gas hydrate between the pair of compression rolls.
An apparatus for producing gas hydrate pellets, comprising:
- a first roll that rotates;
- a second roll and a third roll which are arranged close to and in parallel with the first roll, and each of which rotates in an opposite direction to that in which the first roll rotates;
- and
- feeding means for feeding a gas hydrate between the first roll and the third roll, wherein
- the second roll has a plurality of molds formed in an outer peripheral surface thereof, and
- the gas hydrate is dewatered by the first roll and the third roll, and subsequently the dewatered gas hydrate is compression-molded by the first roll and the second roll.
