HOW TO DEGAS A VISCOUS LIQUID BY ULTRASOUND?
Do you know what #degassing is❓ ❓ ❓
In #industrial manufacturing, it is an important step to guarantee the stability and quality of the products and the respect of the production standards.
➡️ In fact, degassing is the removal of free and dissolved gases from liquids.
✅ Conventional methods can use mechanical and thermal means, but this can be time consuming and require high energy consumption as it is necessary to achieve homogeneity in the entire volume.
✅ Power ultrasound generates cavitation that offers significant mechanical and thermal effects on a local scale and then dissipate completely.
✅ Thus, the use of ultrasound accelerates the coalescence of gas bubbles, thus facilitating their migration to the surface. This migration is also facilitated by a decrease of the viscosity in the liquid.
⁉️ The constraints associated with our test were to remove the gas dissolved in a viscous liquid using ultrasound without increasing the temperature significantly (ΔT = 5°C).
