Degassificació

Degassificació 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 properties or performance of the liquid. For example, in the production of plastics, dissolved gases in polymers can lead to defects in the final product. In scientific research, degassed solvents are often required for accurate spectroscopic measurements.

Various methods can be employed for degassification. One common technique is vacuum degassing, where the liquid is subjected to reduced pressure. This lowers the solubility of the gases, causing them to evolve out of the liquid. Another method is sparging, which involves bubbling an inert gas, such as nitrogen or argon, through the liquid. The inert gas displaces the dissolved gases, which then escape into the atmosphere. Heating the liquid can also aid in degassification, as gas solubility generally decreases with increasing temperature. Stirring or agitation can further enhance the removal of gases by increasing the surface area exposed to the vacuum or sparging gas. The choice of method depends on the specific liquid, the type and amount of dissolved gases, and the required level of gas removal. Degassification is a crucial step in ensuring the purity and quality of many liquids used in diverse fields.
