Abstract
The present invention provides non-venting transfer systems and methods related to transferring cryogenic liquid between two vessels without venting evaporated cryogenic liquid into the atmosphere. The stations, systems, and methods utilize a feed line and a return line connecting a source tank and a pump system to allow for flow of a cryogenic liquid to the pump and return of evaporated cryogenic liquid to the source tank, thereby avoiding release of the evaporated cryogenic liquid into the atmosphere.
