METHOD FOR LOADING STORAGE CONTAINER WITH HYDROCARBON GAS FOR COMPRESSION STORAGE OR ADSORPTION STORAGE OF THE SAME

摘要

PROBLEM TO BE SOLVED: To provide the subject method capable of suppressing the temperature rise inside a storage container and increasing the storage density of a hydrocarbon gas in the container.;SOLUTION: This method comprises the following procedure: top and bottom both ends of a hydrocarbon gas storage container 10 are furnished with methane inlets 20 in advance; to load the container 10 with a hydrocarbon gas, a CNG (compressed natural gas) is first introduced via the inlet 20 on the top of the container 10 into the container 10, and midway of the loading, the gas inlet 20 to be used is switched to the other gas inlet 20 at the bottom of the container 10; thereby a part where heat is generated at first is cooled owing to the adiabatic expansion of the CNG, and as for a part where heat is generated by introducing a CNG afterwards, temperature rise is suppressed since the temperature has fallen by the adiabatic expansion occurred when the CNG was introduced at first.;COPYRIGHT: (C)2001,JPO
