Degassing (deaeration, in the case of air) is the process of removing dissolved gasses and/or small entrained gas bubbles from a liquid. It is one of the most common applications of ISM's ultrasonic technology, which provides the means of removing gasses from a variety of liquids, including water, candle waxes, polymers, epoxies, silicone oils, adhesives, coatings, beverages, inks, paints, transformer oils, emulsion and suspension products, motor oils and many more. Degassing can significantly contribute to the qulity of the final product (fewer defects, improved aesthetics, etc.), making it a very desirable process for many companies. In this video we demonstrate the processes of ultrasonic degassing and deaeration of a high-viscosity (17,500 cps) polymer oil, carried out in the batch mode.

Ultrasound can be used as a commercial-scale degassing technique with ISM's Barbell Horn Ultrasonic Technology:

Do you need to perform continuous degassing? Unlike vacuum degassing, ultrasonic processors can be used in the continuous flow-through mode. Check out the ISP-3600 ultrasonic processor:

Oh, I will try.

this would be perfect for silicone degassing in addition to a vacuum.

The degassing primarily occurs near the surface of the horn, so by adjusting the horn immersion depth and/or position it may be possible to achieve such targeted degassing.

Hello Alexey, do you work in this industy? Currently i need to degass small volumes of water, 500ml per time. the process i use now is basically to fill a syringe with the water at a sufficient speed to cause cavitation in the syringe inlet. from there I find that the water is degassed well enough that even some small gas bubble that find their way in to my application are quickly reabsorbed over a few hours. Id like to increase the capacity of my process and remove the need for the syringe. do you think, A, this process could help me, and B are you aware of any small and ecconomial devices on the market now? This looks like a good process for me.

@@PhysicsHack Why do we need to degas?

Is it possible to accurately target a region to only degas a certain layer or area of the liquid?

At about 3:35, the degassing becomes markedly violent - what is happening to cause this? Has a setting changed in ultrasonic equipment?

Our processors operate in the constant-amplitude mode. Once the amplitude is set, it will always remain at the same level. The power provided by the generator is automatically adjusted based on a principle similar to that used in the cruise control of a car, where engine power output is increased when going uphill in order to maintain constant speed (amplitude, in our case). When volatile fractions are degassed from the oil, its properties abruptly change: cavitation enters into vacuum-bubble regime instead of gas-filled bubble regime. This leads to higher power draw for the same amplitude and, therefore, results in much more violent cavitation. Sometimes this power jump is used as an automatic method of determining the end of the degassing process.
