Embodiment Construction

[0027] Such as figure 1 As indicated, a preferred embodiment of the helium recovery plant ( 1 ) object of the present invention is described below.

[0028] Such as figure 1 As shown in , the helium recovery device (1) consists of five modules: recovery module (2), pressurized storage module (3), purification module (4), liquefaction module (5), and distribution module (6) .

[0029]In this recovery module (2), gas is recovered from a series of scientific or medical installations (7) by means of a recovery module (2) ensuring maximum and minimum pressure conditions of the scientific or medical installation (7), such that such installations ( 7) Independently of other modules (3, 4, 5, 6) and ensure lossless recovery. The recovery module (2) includes electronic pressure sensors as well as safety and shut-off valves to evacuate excess helium in case of excessive and unforeseen evaporation in the unit (7).

[0030] Once recovered through the recovery module (2), the helium of...

Abstract

The present invention relates to a helium-recovery plant that does not generate losses and that allows the continuous supply of helium in equipment requiring said element for refrigeration, or for the storage thereof when the distribution thereof is unnecessary.

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...
