degazacj

Degazacja, in general sense, refers to the removal of dissolved gases from liquids or the removal of gas from a system to achieve a lower gas content. It is used across science and industry to improve process stability, product quality, and material performance. Common target gases include oxygen, carbon dioxide, nitrogen, and other volatile components that can influence corrosion, reactions, or physical properties.

Several techniques are used to achieve degazation. Vacuum degassing reduces pressure to drive dissolved gases out of the liquid. Thermal degassing increases temperature to lower gas solubility and encourage release. Membrane degassing employs gas-permeable membranes to separate gases based on selective permeability. Gas-stripping or sparging injects an inert gas or steam to entrain volatile components and carry them away. Ultrasonic degassing uses high-frequency waves to form and coalesce bubbles that escape. Centrifugal or mechanical degassers exploit differences in density to separate gas from liquid, often in combination with vacuum or heating. In industrial settings, deaeration towers or vacuum deaerators are common in boiler feeds and process streams.

Applications span water treatment, boiler and cooling systems, beverage and food production, electronics and pharmaceutical manufacturing, polymer processing, and petrochemical or nuclear industries. Degazation helps prevent oxidation and corrosion, stabilizes shelf life, reduces bubble formation during casting, and improves chemical purity and process reliability. Effectiveness depends on temperature, pressure, gas solubility, and the specific equipment design. Proper measurement of dissolved gases, using oxygen probes or gas content analysis, is essential to verify performance and prevent reintroduction of gases during handling and storage.
