There are standards for high purity laboratory gases. Usually, the highest percentage of purity is for laboratory applications and, accordingly, the price will be higher. However, lower purity percentages are used for industrial purposes and have more affordable prices. Different types of purity can be supplied for hydrogen gas.Types of hydrogen gas purity
Hydrogen with a purity of about 99.99% or grade 4 has been introduced for suitable industrial applications
Also, hydrogen grade 5 with 99.999% purity and hydrogen grade 5.5 with 99.9995% purity are also used for industrial applications.
Hydrogen with higher purity than grades 4 and 5, such as grade 6 with a purity of 99.9999%, will be suitable for laboratory and research applications.
If you need hydrogen gas capsules for industrial, laboratory or research applications, Zagros Air Liquid Company can deliver the hydrogen you need. Zagros Air Liquid Company imports all kinds of high purity gas capsules and one of these high purity gas capsules is hydrogen. We have been able to provide high purity hydrogen gas capsules with good quality and reasonable price and deliver them to our customers. It should be noted that Zagros Air Liquid Company sells accessories for hydrogen capsules, including hydrogen regulators, at reasonable prices. To buy hydrogen capsules and its equipment, you can use the purchase form or contact a sales expert.Various applications have been defined for hydrogen gas. In the past, hydrogen has been used to fill flying balloons due to its low density and light weight compared to air. But due to its dangers and its extreme flammability, it has gradually given its place to helium gas. They use pure hydrogen or its mixture with nitrogen in detecting leaks and finding tiny holes in power plants, telecommunications, automobile manufacturing, etc. This gas is used in large quantities for hydrogenation of vegetable and animal oils to produce margarine and other fats, hydration of petroleum products and hydrodesulfurization to remove sulfur from fuel.
Hydrogen in industry
Hydrogen is used in the glass industry to fuel the oxygen-hydrogen burner in connection with quartz glasses
High purity hydrogen is widely used in the electronics industry as a reducing agent and carrier gas
It is also used as a carrier gas in gas chromatography
Hydrogen is also used in welding and cutting metals
Hydrogen is used to produce ammonia gas during the Haber process
It is used to produce some types of alcohols such as methanol
This gas is used to produce hydrochloric acid along with chlorine gas
Hydrogen can also be used in metal ore regeneration
It has a very high heat capacity in cooling and is used as a coolant under safe conditions
Sources of hydrogen gas production
Hydrogen has different sources for production. The methods for its production can be divided into two categories: laboratory and industrial. Methods that include chemical reactions are mainly in the category of laboratory production methods. One of its production sources is the natural gas production site. Another source of production is the chloralkali process, which is the electrolysis of sodium chloride solution to produce chlorine, and hydrogen is also obtained as one of the products. Also, hydrogen is produced from the recycling of oil refineries (which is an economical and affordable method) and the recycling of coke oven gas in the steel industry. The most common way is to produce hydrogen gas from water, that is, to produce hydrogen through electrolysis of water
The dangers of hydrogen
Since hydrogen gas is highly flammable, safety measures must be observed when using it and the dangers of hydrogen gas must be taken seriously. The temperature of the hydrogen flame is about 500 degrees Celsius, which is very high and emits ultraviolet rays. For this reason, leaking and catching fire of hydrogen is extremely dangerous. The seriousness of the danger of this gas determines that its transportation should be done carefully and delicately and should never be placed next to other flammable gas capsules, especially oxygen and nitrous oxide gas. In order to strictly observe safety precautions, hydrogen capsules should be kept away from direct sunlight and exposure to heat. Hydrogen capsules should never be rolled on the ground and it is very important to maintain the health of the capsule body.
