Degaseerimine

Degaseerimine is a process used to remove dissolved gases from liquids. This is important in many industrial and scientific applications where the presence of gases can negatively affect the product or process. For example, in the production of plastics, dissolved gases can cause bubbles in the final product, compromising its strength and appearance. In water treatment, removing dissolved gases like oxygen can prevent corrosion in pipelines.

Various methods are employed for degaseerimine. Heating the liquid is a common technique, as the solubility of gases generally decreases with increasing temperature. Vacuum degaseerimine involves reducing the pressure above the liquid, which lowers the partial pressure of the dissolved gases and encourages them to escape. Sparging, where an inert gas is bubbled through the liquid, can also help to carry dissolved gases out. Other methods include centrifugation and the use of membrane contactors.

The choice of degaseerimine method depends on factors such as the type of liquid, the specific gases to be removed, the required level of gas removal, and economic considerations. The effectiveness of degaseerimine is often measured by the concentration of dissolved gases remaining in the liquid after the process. Maintaining low levels of dissolved gases is crucial for ensuring product quality and process efficiency in many fields.
