1. What are industrial gases?

Industrial gases are gaseous materials manufactured for industrial use. The main gases provided are nitrogen, oxygen, carbon dioxide, argon, hydrogen, helium, and acetylene. Although many other gases and mixtures are also available in gas cylinders.

The industry that produces these gases, also known as industrial gas, is considered to include the provision of equipment and technology for the production and use of gases. Their production is part of the broader Chemical Industry (where it is often referred to as “specialty chemicals“).

Some commercial scale business is carried out. Usually through local bound dealers, who are supplied wholesale. This business includes the sale or rental of gas cylinders and related equipment to merchants and sometimes the public. This includes products such as helium gas, brewing gas for beer kegs, welding gas and welding equipment, LPG and medical oxygen.

3. Early history of industrial gas

The first natural gas used by humans was almost certainly air when it was discovered that blowing or fanning a flame made it burn brighter. People also use the warm gas from the fire to smoke food and the steam from boiling water to cook the food.

Carbon dioxide gas bubbles form foam on fermented liquids such as beer

  • Carbon dioxide has been known since ancient times as a by-product of fermentation. Especially for drinks, first recorded dating from 7000–6600 BC in Jiahu, China.
  • Natural gas was used by the Chinese around 500 BC. When they discovered the potential to transport permeable gas from the ground in rudimentary bamboo pipes to where it was used to boil seawater.
  • Sulfur dioxide was used by the Romans in winemaking. Because it has been discovered that burning sulfur candles inside empty wine bottles helps them stay fresh and prevents them from smelling of vinegar.

The original understanding included empirical evidence and the premise of alchemy.

  • However with the advent of the scientific method and the science of chemistry. These gases are better identified and understood. The history of chemistry tells us that several gases have been identified. And either discovered or first during the industrial revolution of the 18th and 19th centuries by chemists in laboratories.
  • Timeline of detection of various gases such as carbon dioxide (1754), hydrogen (1766), nitrogen (1772), oxygen (1773), ammonia (1774), chlorine (1774), methane (1776), hydrogen sulfide ( 1777), carbon monoxide (1800), hydrogen chloride (1810), acetylene (1836), helium (1868), fluorine (1886), argon (1894), krypton, neon and xenon (1898) and radon (1899).

Carbon dioxide, hydrogen, nitrous oxide, oxygen, ammonia, chlorine, sulfur dioxide and manufactured fuel gases were used in the 19th century, and are mainly used in food, refrigeration, medicine, as well as fuels. materials and gas.

  • Carbonated water has been produced since 1772 and commercialized since 1783
  • Chlorine was first used to bleach textiles in 1785
  • Nitrogen was first used for dental anesthesia in 1844.
At this time, the gas is usually made for immediate use by chemical reactions. A notable example of a generator is the Kipps device which was invented in 1844 and can be used to generate gases such as hydrogen, hydrogen sulfide, chlorine, acetylene and carbon dioxide by gas conversion reactions. simple.
Acetylene has been produced commercially since 1893, and acetylene generators have been used since about 1898 for gas production and gas lighting. However, electricity became more practical for lighting and once LPG was commercially produced from 1912, the use of acetylene died.
Once the gas was discovered and produced in modest quantities. The process of industrialization is driving the innovation and invention of technology to produce large quantities of gases.
Notable developments in the gas industry include:
  • The process of electrolysis of water to produce hydrogen (1869) and oxygen (since 1888).
  • The Brin process for oxygen production was invented in 1884.
  • Chloralkali process to produce chlorine in 1892.
  • Haber process for ammonia production in 1908.

The development of applications in refrigeration also led to advances in air conditioning and the liquefaction of gases.

Carbon dioxide was first liquefied in 1823. The first vapor compression refrigeration cycle using ethers was invented by Jacob Perkins in 1834. A similar cycle using ammonia was invented in 1873. And a cycle. another process with sulfur dioxide in 1876.

  • Liquid oxygen and liquid nitrogen were both first produced in 1883.
  • Liquid hydrogen was first produced in 1898 and liquid helium in 1908.
  • LPG was first produced in 1910. A patent for LNG was filed in 1914 with the first commercial product in 1917.

Although no event marks the beginning of the industrial gas industry, many attribute it to the 1880s with the construction of the first high-pressure gas cylinders.

  • Initially, cylinders were mainly used to capture carbon dioxide during carbonization or in the preparation of beverages. In 1895, refrigeration compression cycles were further developed to allow air to liquefy.
  • Most notably by Carl von Linde allowing for the production of larger amounts of oxygen and in 1896 it was discovered that large quantities of acetylene could be dissolved in acetone and produced. The absence of explosives allows for safe bottling of acetylene.
  • A particularly important application has been the development of welding and metal cutting performed with oxygen and acetylene since the early 1900s. As processes for the production of other gases were developed, many other gases were sold. in flasks without a gas generator.

4. The popularity of industrial gases

Industrial gases serve many common purposes in our everyday world. They are naturally divided into three recognizable categories and are transported in cylinders, as bulk liquids or through pipelines. Common types of heaters allow us to warm our homes. Float a balloon and perform dental procedures with no worries.

a. General Atmosphere


  • Nitrogen is a reactive gas. It combines with other elements to create everyday uses such as: fertilizers, food preservation, pharmaceutical applications and is also useful in steel-related manufacturing and construction.


  • We breathe oxygen to live. But beyond this, oxygen has other practical uses. It is used in welding, in wastewater treatment and can kill bacteria. Oxygen is also an antidote to carbon dioxide poisoning and allows divers to breathe underwater.


  • Although not a household name, argon is the basis for the production of a good household product. This gas is present in every type of light bulb in your home and factory.

b. Gas derived from natural gas


  • Methane is a double-edged sword of gas. Although it is the main component of natural gas that you use to cook and heat your home. But in the wrong concentration can also be deadly. Known for its “greenhouse effect“, it can be almost as deadly as carbon dioxide. Because of its properties: invisible, odorless and generally flammable.


  • Helium is best known for its ability to make balloons fly, but it has a further purpose. It is a preventive gas in the art of arc welding and pressurizing the fuel tanks in rockets.

5. The process of creating industrial gas
