Helium Extraction From Natural Gas

Helium (He), as a rare inert gas that cannot be synthesized artificially, is extracted from natural gas and widely used in the following key fields:

1. High-Tech Industries

Semiconductor Manufacturing: Used as a protective and etching gas in wafer processing to prevent oxidation.

Optical Fiber Production: Creates an oxygen-free environment during fiber drawing to ensure transmission quality.

Aerospace & Rocket Propulsion: Serves as a pressurizing and purge gas for cryogenic fuels (e.g., liquid hydrogen) or for satellite cooling systems.

2. Medical Applications

Magnetic Resonance Imaging (MRI): Maintains the ultra-low temperature environment required for superconducting magnets (liquid helium cooling).

Respiratory Therapy: Helium-oxygen mixtures ("heliox") alleviate breathing difficulties in patients with airway obstructions.

3. Industrial & Energy Uses

Leak Detection: Utilizes helium’s low molecular weight and high permeability to detect micro-leaks in pipelines or containers.

4. Scientific Research & Special Applications

Superconductivity Research: Maintains cryogenic conditions for superconducting materials.

Deep-Sea Diving: Replaces nitrogen to prevent "High-Pressure Nervous Syndrome" (e.g., in heliox mixtures).

Balloons & Airships: Safe lifting gas (non-flammable, lighter than air).

Application Scenario:

External sales, etc.
