Abstract

See full text

A process for collection, storage and transport of boil off-gas from a liquefied natural gas storage tank. An ultra-low temperature, composite gas tank is provided to accept the boil-off gas and saturated vapor at ultra-low-temperatures in a range of about −80° C. to −45° C. (about −112° F. to −229° F.) and at high pressure of about 150 bar (about 2,175.5 psi). Boil off gas collected from liquefied natural gas storage at a pressure in a range of about 15 to 18 bar (217.5 psi to 261 psi) and at a temperature in of about −150° C. (about −238° F.). The ultra-low temperature, composite gas tank can hold the gas as it warms to ambient temperature. The process includes a liner step; a filament step; a wrap step; and a filling step. Optional steps include an insulation step; a fiber step; a layering step; a nozzle step; and a gas step.
