To improve a method for dehydrating natural gas generated through thermal cracking of a clathrate hydrate.
The clathrate hydrate is dispersed in a slurry 10. The apparatus comprises a slurry-pressurizing pump 4 for pumping out the slurry 10 from a storage tank 1 where the slurry 10 is stored, a separator 7 for separating the thermally cracked slurry 10 into three phases, i.e. natural gas 16, a dispersion medium 17 and water 18, a regenerating heat exchanger 5 for exchanging heat between the natural gas 16 generated in the separator 7 and the slurry 10, a heat separator 6 for re-heating a fluid discharged from the regenerating heat exchanger 5 and sending it to the separator 7, a cryogenic condenser 8 for cooling the natural gas 16 discharged from the regenerated heat exchanger 5 to cryogenic temperature, a pipeline for successively sending the dispersion medium 17 separated by the separator 7 to the regenerating heat exchanger 5 and the cryogenic condenser 8 so that it flows down the walls on the natural gas side of these heat exchangers and a KO drum 11 for receiving the fluid from the cryogenic condenser 8 and separating it into natural gas and the dispersion medium.
