China Wholesale So2 Gas Pricelist – Hydrogen (H2) – Taiyu

Technical parameters 

Hydrogen has a chemical formula of H2 and a molecular weight of 2.01588. Under normal temperature and pressure, it is an extremely flammable, colorless, transparent, odorless and tasteless gas that is hard to dissolve in water, and does not react with most substances. However, under higher pressure and moderate temperature conditions, hydrogen reacts with many hydrocarbon materials in a catalytic reaction. Hydrogen is the least dense gas known in the world. The density of hydrogen is only 1/14 that of air, that is, at 1 standard atmosphere and 0°C, the density of hydrogen is 0.089g/L. Hydrogen is the main industrial raw material. Petroleum and chemical industries require a large amount of hydrogen. Among them, the processing of fossil fuels and the production of ammonia by the Hubble process are the main applications. In addition to being used in chemical reactions, hydrogen also has a wide range of applications in physics and engineering. It can be used as a shielding gas in some welding methods. Hydrogen is also an important industrial gas and special gas, and it has a wide range of applications in the electronics industry, metallurgical industry, food processing, float glass, fine organic synthesis, aerospace, etc. At the same time, hydrogen is also an ideal secondary energy (secondary energy refers to the energy that must be produced from a primary energy such as solar energy, coal, etc.) and gas fuel. It burns as a transparent flame, which is difficult to see. Water is the only Products of combustion. Hydrogen can also be used as a raw material for synthetic ammonia, synthetic methanol, and synthetic hydrochloric acid, as a reducing agent for metallurgy, and as a hydrodesulfurization agent in petroleum refining. Because hydrogen is a flammable compressed gas, it should be stored in a cool, ventilated warehouse. The temperature in the warehouse should not exceed 30°C. Keep away from fire and heat sources. Avoid direct sunlight. It should be stored separately from oxygen, compressed air, halogens (fluorine, chlorine, bromine), oxidants, etc. Avoid mixed storage and transportation. The lighting, ventilation and other facilities in the storage room should be explosion-proof, with switches located outside the warehouse, and equipped with corresponding types and quantities of fire-fighting equipment. Prohibit the use of mechanical equipment and tools that are prone to sparks
