Uses of hydrogen:
Metal smelting:
Metal smelting:
Hydrogen is a very good reductant for smelting important metals, such as tungsten, molybdenum, cobalt, nickel and so on.
Chemical raw materials: hydrogen is an important raw material for synthesizing ammonia, synthesizing methanol, synthesizing hydrochloric acid, etc. It is also a reducing agent for metallurgy.
Energy: Hydrogen is a high calorific value fuel, which can be used in all kinds of combustion equipments, and can also be used as the fuel of fuel cell to produce electricity and heat.
FAT HYDROGENATION: Hydrogen is used in the process of hydrogenating fats in products such as margarine, cooking oil, shampoo, lubricants, and household cleaners.
Glass Manufacturing and Electronic Microchip Manufacturing: Hydrogen is added to a protective gas of nitrogen to remove residual oxygen during the manufacturing process.
Helium Uses:
Vacuum Leak Detection: Helium is widely used in vacuum leak detection because of its excellent permeability and diffusivity. By filling the system to be inspected with helium and then using a helium mass spectrometer to detect the leaked helium, the location of the leak in the system can be quickly and accurately determined.
Cryogenic technology: Helium is the substance with the lowest known boiling point and can be used as an ultra-low-temperature refrigerant in high-tech fields such as superconducting technology, atomic reactors, spacecraft and rockets.
Medical: Helium is used in the medical field mainly in the cooling systems of magnetic resonance imaging (MRI) equipment to maintain stable operation.
Welding and Cutting: Helium can be used as a shielding gas to prevent workpieces from being oxidized by oxygen in the air during the welding and cutting process.
Ballooning and blimps: Helium is the second least dense gas after hydrogen and can be used to fill balloons and blimps to keep them afloat.
In short, hydrogen and helium have a wide range of applications in their respective fields, with helium being particularly important in vacuum leak detection.
