Method and apparatus for producing clathrate hydrate slurry, and method for operating the same apparatus

摘要

A method of producing a clathrate hydrate slurry, includes a step of heat-exchanging an aqueous solution of a guest compound for the clathrate hydrate or a slurry of the clathrate hydrate dispersed or suspended in an aqueous solution or water with a refrigerant thereby generating the clathrate hydrate in the aqueous solution or the slurry, in which a part of the clathrate hydrate deposited on the heat transfer surface in the process of heat exchange with the refrigerant is removed by adjustment of a temperature of the refrigerant and flow force of the aqueous solution or the slurry and the rest is kept remained as it covers the heat transfer surface.
