Abstract
An apparatus produces hydrate slurry, which is a mixture of aqueous solution and hydrate, by cooling aqueous solution containing a guest compound, which generates the hydrate at temperature higher than 0° C., by using a cooling medium. The apparatus includes a first heat exchanger for supercooling the aqueous solution while holding the aqueous solution in a liquid state and in a second heat exchanger, which is provided on the downstream side of the first heat exchanger for cooling hydrate slurry.
Claims23
An apparatus for generating hydrate slurry, wherein the hydrate slurry is a mixture of aqueous solution and a hydrate, the hydrate slurry is generated by cooling aqueous solution containing a guest compound by using a cooling medium, and the guest compound generates a hydrate at temperature of more than 0° C.,
- the apparatus comprising a first heat exchanger and a second heat exchanger, the first heat exchanger supercooling the aqueous solution while holding the aqueous solution in a liquid state and the second heat exchanger cooling the hydrate slurry, the second heat exchanger being provided on the downstream side of said first heat exchanger.
In an apparatus for generating hydrate slurry containing a hydrate of guest compound by cooling aqueous solution containing a guest compound which generates a hydrate at temperature of higher than 0° C., the apparatus comprising:
- a refrigerating machine having a plurality of evaporators provided so as to be switchable;
- a circulation system for the aqueous solution of the guest compound, so as to cool the aqueous solution of the guest compound by each of said evaporators;
- controlling means for stopping cooling the aqueous solution of the guest compound in one evaporator when the circulation system for the aqueous solution of the guest compound in the evaporator is blocked, and the circulation system for starting cooling the aqueous solution of the guest compound in another evaporator;
- and
- means for supplying a high-temperature refrigerant in said refrigerating machine to an evaporator in which cooling the aqueous solution of the guest compound stops.
