<p>PURPOSE:To totally eliminate the need for using energy for pressurizing by alternately receiving a liquefied gas in more than one small-capacity high pressure resistant storage tank, introducing a part of this liquefied gas out and gasifying it utilizing air, hot drain etc., and pressurizing the inside of a storage tank by means of this gasified gas. CONSTITUTION:After a prescribed pressure is reached in a storage tank 100, a liquefied-gas delivery valve 104 is opened, to start the delivery of the liquid. The liquefied gas, which passed through the liquefied-gas delivery valve 104, passes through a pipe 116 and enters a delivered gas evaporater 3, exchanges heat with air, hot drain, sea water, etc. to be gasified, and is sent out to a requiring part as a high pressure gas. During this time, the liquefied gas delivery valves 204, 304 for storage tanks 200 and 300 are left closed. Thus, with at least three high pressure storage tanks 100, 200, 300 being provided, and by carrying out each process of receiving liquid, prepressurization, pressurization, sending with pressure, and discharging remaining gas, repeatedly with the period for each storage tank being shifted, the pressurization and sending with pressure, of a liquefied gas can be carried out.</p> |
