Abstract
A two line system for storing and dispensing cryogenic liquids from a bulk storage tank to a secondary container without the use of a cryogenic pump. A first line is in communication with the vapor space of a secondary container and a compressor, the compressor being used to depressurize the secondary container to a point where the bulk storage tank is at a higher pressure than the secondary container. The first line can direct the evacuated gas either into the bulk storage tank, towards separate holding tanks, or towards any other application. A second line is in communication between the bulk storage container and the secondary container. When the compressor is activated, the pressure in the secondary container will fall below the pressure in the bulk storage tank, causing the cryogen to flow from the now higher pressure bulk storage tank into the secondary container.
