Title:
SEPARATION/RECOVERY DEVICE AND GAS-HYDRATE RECOVERY SYSTEM
Document Type and Number:
Japanese Patent JP2018071059
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To improve a separation/recovery device and gas-hydrate recovery system more efficiency.SOLUTION: A separation/recovery device 4 is provided with a storage part 10 to form a separation space B insides, a reciprocation moving part 11 to change a volume of the separation space B by means of a reciprocating drive, and a drive part 8 to drive the reciprocation moving part 11. The storage part 10 is provided with an introduction port P1 for introducing sediment containing gas-hydrate into the separation space B in an open state, at the time of the reciprocation moving part 11 taking a first position, recovery port P2 for recovering the gas separated from the gas hydrate from the separation space B of an enlarged volume and depressurized pressure in the open state by the movement of the reciprocation moving part 11 from the first position to a second position, and a discharge port P3 for discharging the sediment T2, at the time of the reciprocation moving part 11 moved from the second position to the first position.SELECTED DRAWING: Figure 2
