Abstract Gas porosity is a major factor in the quality and reliability of castings. The major cause of gas porosity in castings is the evolution of dissolved gases from melting and dross or slag containing gas porosity. Degassing is the process of removing these gases.

Plasmonic nanoheater for formaldehyde degassing
Chemical Engineering JournalFormaldehyde, a harmful indoor air pollutant with carcinogenic and irritative effects, poses significant health risks and economic burdens. However, formaldehyde is commonly utilized as an adhesive in wood and wood composites, with aldehyde-based resins frequently found in paints, flooring, and furniture.

The discovery of 3He in basaltic glasses and in seawater that has cycled through mid-ocean ridges has confirmed the reality of the release of juvenile gases from the mantle today. The rate of 3He loss from the mantle is now reasonably well-known. Since the ratio of the concentration of this nuclide to that of 20Ne, 36Ar, 84Kr, 132Xe has been measured ...

Overview of Ultrasonic Degassing Development
2017Ultrasonic degassing attracts industrial attention as an alternative to Ar-rotary and Ar-lancing degassing, offering environmentally friendly, economical and efficient technology. This paper gives a brief historical overview of ultrasonic degassing development in the 1960s–2010s, discusses basic principles of cavitation-induced degassing and ...

Earth’s CO2 degassing in Italy
2010Earth’s CO2 emission in Italy includes both volcanic and non-volcanic degassing, with measured CO2 fluxes of about 35 - 60 Mt/y. Zones of non-volcanic CO2 emission include Tuscany, Latium, Campania, the Apennines, Sicily, and Sardinia. Volcanic emissions are particularly abundant at Mt.

Abstract Gas exsolution and segregation are fundamental controls on eruption dynamics and magma genesis. Basaltic magma loses gas relatively easily because of its low viscosity. However, bubbles grown by decompression and diffusion during magma ascent are too small to segregate.

Degassing Processes and Chemistry
2015Degassing of volatile-bearing solids requires addition of energy in order to liberate the volatile elements from various compounds contained within the (initially) meteoritic rocks. There are two main sources of this energy: 1) that associated with the kinetic energy of impacting bodies and 2) heat from within the Earth, either in shallow, hydrothermal
