METHODS AND SYSTEMS FOR DENSIFYING A LIQUID FUEL USING A LIQUID NITROGEN BATH

摘要

A method for densifying liquid methane is described. The method includes passing the liquid methane through a liquid nitrogen bath, self-pressurizing a container associated with the liquid nitrogen bath through boil off of the liquid nitrogen within the container, and regulating pressure within the liquid nitrogen container to maintain a boiling point of the liquid nitrogen above the triple point temperature of the liquid methane passing through the liquid nitrogen bath.
