Degasification (/diːˌɡæsɪfɪˈkeɪʃən/) is the process of removing gases or volatile components from a liquid or solid material. The spelling of this word may seem confusing due to the variety of vowels and consonants used. However, following the International Phonetic Alphabet (IPA), the pronunciation becomes clearer. The word starts with a stressed "dee" sound, followed by a long "a" sound and a stressed "sif" sound. The ending is pronounced with an unstressed "kay" sound, a stressed "shuh" sound, and an unstressed "un" sound.
Degasification is a process aimed at removing or reducing the presence of gases, typically dissolved gases, in a substance or a system. It involves the extraction, elimination, or transformation of gases, particularly in liquids or solids.
In the field of chemistry, degasification refers to the removal of dissolved gases from a liquid. This is commonly achieved through various techniques such as heating, vacuum degassing, or the introduction of an inert gas to displace the dissolved gases. By eliminating these gases, the liquid becomes purer and more stable, often facilitating subsequent processes or reactions.
In the context of mining and industrial applications, degasification is the procedure used to remove potentially harmful or flammable gases, mainly methane, from underground structures like mines, tunnels, or coal seams. The purpose of degasification in this context is primarily safety-oriented, as the removal of these gases reduces the risk of explosions, improves air quality, and protects workers.
Furthermore, degasification can also be employed in the realm of environmental preservation. It refers to the elimination of harmful gases, such as carbon dioxide or methane, from sources like landfills, wastewater treatment plants, or industrial facilities. This process aids in reducing greenhouse gas emissions, preventing pollution, and mitigating climate change.
Overall, degasification encompasses a range of procedures employed to remove or decrease the amount of gases present in different substances or systems. It is implemented in various fields, including chemistry, mining, industry, and environmental conservation, to ensure safety, enhance purity, and minimize the negative impact of gases.
The word "degasification" is derived from the combination of two terms: "de-" and "gasification".
- The prefix "de-" is of Latin origin and it means "from; down; away" or "completely". In this context, it implies the removal or reduction of something.
- "Gasification" comes from the word "gasify", which is in turn derived from the noun "gas". The term "gas" dates back to the early 17th century and originates from Dutch and German roots. It initially referred to "chase" or "terrify" but later came to denote a state or form of matter.
- "Gasification", then, refers to the process of converting a substance into a gas or vapor form.
When combined, "de-" and "gasification" form "degasification", which means the act or process of removing or reducing gases.
