Title:
BOILOFF GAS CONDENSING DEVICE AND LIQUEFIED GAS STORAGE EQUIPMENT
Document Type and Number:
Japanese Patent JPH1163396
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To suppress the discharge pressure of a boiloff gas(BOG) compressor to conventional low pressure and reduce initial cost and running cost of the BOG compressor. SOLUTION: Condensate 17 in a receiving tank 31 is maintained in a low enthalpy state with low temperature liquefied gas fed from a low temperature tank 11. The low temperature liquefied gas 12 fed from the low temperature tank 11 and mixed with boiloff gas 13 in a chamber 33 is mixed into the condensate 17 to condense the boiloff gas 13. The condensate 17 is boosted and filled into a low temperature liquefied gas delivery system 16 and gasified. Fuel gas is therefore fed in a high pressure state to an electric power plant or the like while suppressing the discharge pressure of a BOG compressor 14 to conventional low pressure.
