Abstract
In another embodiment of the invention, a method for reducing boil-off gas losses from a liquid storage tank having a liquid and boil-off gas contained therein is provided. In one embodiment, the method can include the steps of pumping the liquid from the liquid storage tank to a heat exchanger using a liquid pump; subcooling the liquid within the heat exchanger by using cold energy from vaporization of liquid nitrogen to form a subcooled liquid; and introducing the subcooled liquid to the liquid storage tank, thereby reducing the temperature within the liquid storage tank.
