deoksigenointi

Deoksigenointi, a Finnish term, refers to the process of removing oxygen from a substance or environment. This can be achieved through various methods, depending on the specific application and the substance being deoxygenated. In industrial settings, deoxygenation is crucial for preventing corrosion, particularly in water systems like boilers and pipelines. Oxygen can react with metals, leading to oxidation and degradation, which can compromise the integrity and efficiency of the equipment.

Common deoxygenation techniques include chemical deoxygenation, where oxygen scavengers like sodium sulfite or hydrazine are added to react with and remove dissolved oxygen. Physical deoxygenation methods involve heating the substance to reduce oxygen solubility or using vacuum deaerators to strip oxygen out. In the context of food preservation, deoxygenation can extend shelf life by preventing oxidative spoilage. For example, vacuum packaging removes air, and thus oxygen, from food products. In biological contexts, deoxygenation can refer to environments with very low oxygen levels, such as in certain deep-sea or anaerobic microbial habitats. The term is generally understood as the deliberate or natural reduction of oxygen content.
