Refrigerant gases are used in cooling systems, with different types including CFCs, HCFCs, HFCs, PFCs, and ammonia and carbon dioxide blends. Early refrigerators used toxic gases, leading to the discovery of CFCs. However, their use was banned due to environmental concerns. HCFCs and HFCs are now commonly used, but natural refrigerants like ammonia and carbon […]
The noble gases are a group of elements on the periodic table known for their lack of color, odor, and reactivity. Helium and neon are the most common in the universe, but not on Earth. Their full valence shells make them unlikely to react chemically, and they are used in various scientific and industrial processes. […]
Acid gases, including carbon dioxide and hydrogen sulfide, are common contaminants in raw natural gas and must be removed during refining. This is done through amine gas treatment, which absorbs the acid gases in a solution with amines. The concentrated hydrogen sulfide is then processed to recover elemental sulfur through the Claus process. Acid gases […]
