RE:From "Looming shortage..." article You're right not all do they save all that money at $140 MCF to pay someone else to refine the gas but the argon And krypton gas with the two other gases will pay $38 MCF to handle there gas and to refine it.
1. the other explorers only get $285 MCF then have to pay $140 MCF to refine plus they have to pay for trucking and they lose 10% of the helium every 1500 miles.
2. But best of all when you go straight to the end users with refined helium your price goes up 350% to $1100 MCF. DME clears $1000 MCF the other explorers only get $90 MCF. It's 1100% advantage unbelievable.
