De-aerated refers to the process or state of removing dissolved gases, primarily oxygen and nitrogen, from a liquid. This is commonly done to improve the quality of the liquid, preventing corrosion, reducing the risk of oxidation, and enhancing its stability. The removal of these gases is crucial in various applications, including power generation, beverage production, and pharmaceutical manufacturing, where their presence can lead to undesirable chemical reactions or equipment damage. The method of de-aeration often involves heating, vacuum application, or the use of chemical scavengers to eliminate the dissolved gases. The resulting liquid is then considered to be free or nearly free of air, achieving the state of being de-aerated.
De-aerated meaning with examples
- The power plant's boiler required de-aerated water to prevent corrosion within the pipes and turbines, extending their lifespan and ensuring efficient energy production. Continuous monitoring assured the water remained free of gases. The de-aeration process was integral to maintaining system integrity.
- Brewers utilized de-aerated water in the beer brewing process to preserve the aroma and flavor profiles of the ingredients by minimizing oxidation. The removal of dissolved oxygen was vital. Proper de-aeration techniques ensured clarity and extended shelf life.
- In the pharmaceutical industry, de-aerated solutions were used to prepare sterile injections, preventing oxidation and ensuring the drug's stability and efficacy. Stringent procedures were followed. de-aerated water was a critical ingredient.
- During the production of semiconductors, highly de-aerated solvents were necessary to prevent unwanted reactions during the etching and cleaning processes, ensuring proper device fabrication. Precision was paramount to remove gas residue.
- The researchers used a special vacuum chamber to create de-aerated nutrient solutions for their hydroponic experiments, to provide plants with optimum growing conditions. It improved oxygen diffusion, and provided a stable growing media.
