The primary source of helium is natural gas wells, which are obtained by condensing and stripping operations.
Removal operation: It is a process during which a material is separated from a liquid and enters the vapor or gas phase.
Uses of helium gas:
Helium is neutral and has the least solubility of all gases in liquids. Therefore, as a gas under pressure for:
Cryogenic rocket propellants in rocket/space applications
Heavy water in nuclear reactors
For all liquids at room temperature or lower temperatures
Helium is widely used in the welding industry as a neutral shielding gas for electric arc welding. It is also used in connection with helium leak detectors to test the integrity of systems and built components.
Various mixtures of helium and oxygen are used as breathing gases for divers who have to work at great depths and places with high pressures. Helium can be used instead of nitrogen to dilute oxygen. This prevents nitrogen from dissolving in the blood, which causes nitrogen anesthesia.
Helium is used to fill large high-atmosphere balloons and cosmic ray studies. Small helium balloons are used for weather forecasting to carry meteorological instruments.
Due to its inflammability and low density, this gas is used to fill toy balloons (mixed with nitrogen), airplane tires, advertising balloons, fixed balloons connected to the ground.
Helium mixtures with hydrocarbons are used in leveling the kaiger counter to detect X-rays, alpha, gamma and beta.
Helium is used as a carrier gas or as a purge gas for various semiconductor processes.
Helium is used as a balance and calibration gas in calibration mixtures and as a carrier gas in gas chromatography and as a cleaning and zero gas for alloying instruments.
Helium is used:
As an accompanying cooling and intermediate protection for pulling optical fiber
To cool uranium rods in nuclear reactors
In different types of gas lasers as a buffer or carrier gas
In gas mixtures with neon and argon to fill electronic tubes like neon effect
For interwoven crystal growth (inert atmosphere)
To break the vacuum of the heat treatment furnace
As an airbag activating gas
To create neutral furnace atmospheres in special glass processing and precious metal applications
Liquid helium is used to cool superconducting magnets in NMR (Nuclear Magnetic Resonance) for medical or analytical purposes and in research and development processes.
