degassing

This term is primarily used in technical, industrial, and scientific registers, particularly within metallurgy, chemistry, and geology. It describes a specific physical transition where gases escape a medium, whether through a controlled industrial process to ensure material purity or as a natural reaction to a drop in pressure.

When used as an adjective, it typically modifies equipment or specific stages of a process, such as a degassing unit or a degassing cycle. Because it is derived from a gerund, the noun form refers to the process itself and is treated as an uncountable concept in most technical contexts.
