Helium is thought to be the most abundant element in the Universe. So it is a testament to the competence of the captains of idustry and the free market that the world faces a helium shortage. Something fishy is going on, and I think Bill Clinton knows what it is. See The Quigley Formula.
Helium is found in natural gas, but there are very few extraction plants operating. The biggest was in Qatar and has been shut down. There is another in South Africa:
Here are some ideas about how to make a helium detector, and they also suggest how to start thinking about filtering helium: the thing is, helium atoms are so small and they move so fast at room temperature that they pass through latex, for example much quicker than air, which is why helium balloons need to be made of aluminium foil.
If it is only the helium you need to extract from LNG, then filtering it may the more efficient way to do it.
