DEWATERING DEVICE AND METHOD FOR GAS HYDRATE SLURRYS

摘要

It is required to provide a gas hydrate dewatering device which performs dewatering and produces a gas hydrate with a low proportion of included water (40f) continuously at high efficiency, under conditions in which the gas hydrate is not decomposed and the water is not frozen into ice. This is achieved by providing a dewatering device (12) for gas hydrate slurry (37) which eliminates the water (40e) from a slurry in which gas hydrate is dispersed in water, including a dewatering mechanism of a screw press type (41) within an environment which is maintained at temperature and pressure conditions at which the gas hydrate does not decompose and the water does not freeze.
