ABSTRACT:
A process and apparatus for transfer of liquefied natural gas from a storage tank in subcooled condition using liquefied nitrogen to subcool the liquefied natural gas and nitrogen vapor formed by thermal transfer between the liquefied natural gas and liquefied nitrogen as pressurant to drive the transfer of subcooled liquefied natural gas. This invention provides a liquefied natural gas vehicle refueling station which utilizes nitrogen as a propellant and avoids venting natural gas to the atmosphere.
