Method and system for filling cryogenic liquid containers

Substance loss is minimized in a station for loading a container with cryogenic substance stored in a tank. A throttle vent valve is provided at the outlet vent of a container being loaded for controlling the differential pressure between the storage tank and the container. The throttle vent valve i...

More Information
Summary:Substance loss is minimized in a station for loading a container with cryogenic substance stored in a tank. A throttle vent valve is provided at the outlet vent of a container being loaded for controlling the differential pressure between the storage tank and the container. The throttle vent valve is adjusted to maintain the differential pressure at a value equal to the optimum differential pressure for minimizing substance loss. The optimum differential pressure is selected by determining the filling loss for a plurality of values of differential pressure and selecting the differential pressure which produces the minimum filling loss.
