3. Early history of industrial gases

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.
  • 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.

  • 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

a. General Atmosphere

Nitrogen

  • 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.

Oxygen

  • 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.

Argon

  • 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

  • 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

  • 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 gases

  • Many gases are produced for industrial purposes with a wide variety of applications. The main industrial gases are nitrogen, oxygen, carbon dioxide, argon, hydrogen, acetylene and helium. And precise measurements are needed to ensure gas purity.
  • The industrial gas market includes the production of these high-purity gases, as well as their bottling and shipping. At every stage, gas monitoring is important to prevent the possibility of contamination.
  • Purity is essential to the industrial gas market. Contamination monitoring to ensure high product purity supports end product safety, efficacy and quality in a variety of industries.
  • Our analytical solutions are industry proven to support gas purity and pollution monitoring. They use responsive technologies. Precise is capable of measuring very low concentrations and can operate under demanding process conditions.

Generating gas

  • Cryogenic gas generation systems are used to produce high purity industrial gases, usually from atmospheric air. Nitrogen is the most commonly produced gas by this process.

Air filter

  • Most industrial gases are manufactured to meet specified purity. This requires precise monitoring of any contaminants during production to ensure the required quality is met.

Applications of the container

  • A glovebox is a sealed container used for manipulating objects in a separate, isolated environment. This is usually an inert environment for safe handling of box contents.

Purity of gas

  • Inert gases have a number of applications, and are commonly used in industry to protect a process. To prevent possible explosive or destructive reactions in the air.

UV Drying Cabinet Curing

  • Ultraviolet (UV) light is used in many manufacturing applications. To increase production efficiency and reduce potential risks and errors during drying. Gas monitoring ensures product quality.
