Linde will also construct a new helium processing plant in Freeport to purify and liquify the recovered helium, securing an additional source of liquid helium in the U.S.
Liquid helium Manufacture Most of commercial helium is recovered from natural gas through a cryogenic separation process. Normally, helium is present in less than 1% by volume in natural gas. Helium is recovered, refined, and liquefied. Liquid helium is typically shipped from production sources to storage and transfill facilities.
Because helium is an "inert" gas, it does not react with other elements, which makes it ideal for manufacturing semiconductors. Chemical reactions that take place during the processing of semiconductors are generally gas- or liquid-based, so using inert gas around the silicon prevents unwanted reactions. Also, because helium has a high ...

The ability of helium in its liquid state to seemingly disobey the laws of physics has been the subject of study for almost a century; what occurs is a spontaneous process in which liquid helium rises up and out of its container. Yet this phenomenon is not commonly taught in schools, or even universities for that matter.
