Industrial gas refers to gases that are produced and used in various industrial processes. These gases include oxygen, nitrogen, argon, and carbon dioxide, among others. They play a crucial role in manufacturing, chemical processing, and energy production, serving functions such as combustion, welding, and refrigeration. The production of industrial gases typically occurs through methods like air separation and steam methane reforming. These gases are supplied in bulk or packaged in cylinders for use in industries such as healthcare, food and beverage, and metallurgy. Their versatility makes them essential for modern industrial operations.
