Abstract
Embodiments described herein relate to systems and methods of extracting liquid from empty barrels. In one aspect, a method includes heating a barrel with less than about 10 ml of free liquid disposed therein to expand pores in the barrel. The method further includes applying, after the heating, a negative pressure to an interior of a vessel in which the barrel is disposed, such that an amount of liquid is extracted from the barrel. The method includes collecting, after the applying, the amount of liquid within a collection container. In some embodiments, collecting the amount of liquid includes pumping the liquid through a tube that is disposed between an outer surface of the barrel and the collection container. In some embodiments, heating the barrel is via a heated blanket wrapped around the barrel. In some embodiments, heating the barrel is via placing the barrel in an oven.
