Method for filling a storage tank using liquid cryogen pumping system with reduced heat leaks

Abstract

A method for delivering a liquid cryogen from a liquid cryogen source to a storage tank can include the steps of: providing a bayonet system having an in-line pump disposed therein, the bayonet system having an upstream end and a downstream end; attaching the bayonet system to an upstream conduit, wherein the upstream conduit is in fluid communication with a liquid cryogen source, attaching the bayonet system to a downstream conduit, wherein the downstream conduit is in fluid communication with the storage tank; purging and cooling the upstream conduit and the downstream conduit; and flowing the liquid cryogen from the liquid cryogen source to the storage tank.
