The general purpose of gas is that it is used as a fuel, cooking and heating agent. And it has no fixed size or volume. The space between the particles of a gas is high and produces more force on the container that it is stored in. Also, gases have a low density compared to solids and liquids. There are so many gases existing and used for various applications. Some gases have the same properties whereas, some are entirely different. Types of gas include Welding gases, natural gas, petroleum gas etc. Gases are used in applications like health care, food and beverage, printing technology etc.
Areas of gas use
- Gases used for medical purposes
Oxygen, nitrogen, argon and helium are the most significant gases used in health care. One of the fundamental gases for human life is oxygen. So it has a considerable role in the medical field. It supplies to the patients who have oxygen deficiency. Nitrous oxide gas is performing as an anaesthetic agent in hospitals. For inflating the abdominal cavity and in laparoscopy, carbon dioxide has a sufficient role. Dry ice is also used in the treatment of cataracts in cryotherapy. Surgical instruments are made with inert gases like argon and helium. Because nitrogen is inactive at ambient temperature, it can be used in medical equipment. Also, liquid nitrogen is a part of gynaecology and ophthalmology.
- Gases for heat treatment
The most commonly used inert gases in heat treatment are argon, nitrogen, helium, carbon monoxide, ammonia, methane. Nitrogen has active participation in the heat process like annealing, tempering, brazing and neutral hardening. And it acts as a blanket in the part where heat treatment occurs. Mainly argon is used in the process of sintering. Hydrogen gas is significant in vacuum processes. And it avoids decarburising of steels.
- Industrial gases for water treatment
Oxygen and carbon dioxide are two widely used gases for water purification. The carbon dioxide gas separates almost all impurities in wastewater and converts them for drinking purposes. Using these gases in this process is much more efficient and saves energy. And oxygen supports proper aeration and controls awful odours. PH control is a significant part of water treatment. Adding carbon dioxide can manage the nature of water and can make it acidic. Gases like chlorine and sulphur are used for purification and sterilisation.
Types of gases
- Liquified petroleum gas
It is the most commonly used fuel gas. These are used for both industrial and residential purposes. The main advantage of these is the ease of storage and transport.
- Natural gas
Natural gas is produced through the decomposition of plant and animal waste under high pressure and heat. It’s mostly utilised for cooking, power generation, and industrial applications.
- Calibration gas
These are used for testing analytical instrumentation and results from an accurate measurement. It is also used for measuring air quality and pollutants present in gases and blood.
- Welding gases
Using these prevents impurities from shielding the arc and bestows clean welds. Welding gases like argon and carbon dioxide are the significant two to carry out this purpose.
- Hydrogen gas
Hydrogen gas is utilised to generate energy and heat and has a high calorific value. Several fertiliser productions in Australia are using the properties of hydrogen to develop the industry more. It is a significant item in the Haber process, methanol production and also used as rocket fuel.
- Laser gas
Helium and neon are the two gases that form laser gas. The significant purpose is for cutting and welding, and they support the making of a hologram.
There are so many industrial gas suppliers in Australia. Whatever the gas requirement, one can contact them and ensure safe and risk-free transportation of gases.
