Publication number: 20110023501Abstract: This invention relates to methods and systems for reliable ultra-high purity (UHP) helium gas supply and maintaining dedicated onsite inventory. Specifically, the invention employs multiple ISO containers whereby vaporized UHP helium in the standby ISO container(s) is used to build-up pressure in the online ISO container. The thermal shields of the ISO containers can be used to decrease heat leaks into the backup ISO container thereby decreasing helium vaporation rate and the amount of gas needed to be withdrawn in order to maintain the maximum allowable working pressure (MAWP) of the vessel. An even lower supply rate is possible by drawing UHP helium gas using an economizer valve but maintaining liquid in the ISO container. This makes it possible to efficiently manage the supply rate, from low flows to higher flow requirements, and to optimize UHP helium draw rate from the storage vessels.Type: ApplicationFiled: July 30, 2009Publication date: February 3, 2011Inventors: Thomas Robert SCHULTE, John Joseph BYRNE, Michael Clinton JOHNSON, Shrikar CHAKRAVARTI, Kwamina BEDU-AMISSAH
