Description

[0001] purpose of invention

[0002] The invention relates to a device for recovering helium comprising different modules for subsequent use in different applications, such as refrigeration of medical equipment required in Magnetic Resonance Imaging (MRI).

[0003] The object of the present invention is to obtain a leak-free helium recovery method which will avoid the dependence on fresh helium supply. Background technique

[0004] Although helium (He) is the second most abundant element in the universe, it is rare and difficult to extract on Earth. Helium is found underground in gaseous form as a by-product of natural radioactive disintegration.

[0005] Subsurface He is obtained from natural gas wells by separation methods. It is shipped to suppliers and / or end users in containers under high pressure when in the gaseous state and in insulated containers (Dewars or shipping bottles) at atmospheric pressure when in the liquid state. He in liquid form is obtained by industri...
