@cargo Look forward to hearing about the results from the test campaign which will be presented at TMS 2024. https://www.programmaster.org/PM/PM.nsf/ApprovedAbstracts/683FB0307D8B2513852589DE006FBCF2?OpenDocument

The link below is a research paper about Thermal plasmas for industrial high-temperature processes, which also includes Aluminum Reverberatory Furnaces (2.2 Aluminium Recycling) That screen shot is an example of Stena aluminum recycling process which is described in detail in the research paper.

"Replacing the fossil burners in this process with plasma burners could potentially not only cut carbon emissions from the process but may also improve process efficiency by reducing costs and metal loss. Plasma torches provides high energy density and faster melting rates. A suitable working gas in the plasma burners could provide the blanket cover and eliminate the need of chemical fluxes or inert gases. Reddy et. al. states that use of plasma torch reduces dross producing to less than 0.5% [23]"

@cargo MY guess is that the blanket cover that the plasma torch has the ability to provide when utilized with a suitable gas will inhibit oxidation when the aluminum is remelted. Dross formation and magnesium loss IMO will be minimized when the aluminum is melted. Both Dross formation and magnesium loss will be discussed at TMS 2024 by $PYR. https://www.programmaster.org/PM/PM.nsf/ApprovedAbstracts/683FB0307D8B2513852589DE006FBCF2?OpenDocument

Salazar (Aluminum Director at PYR) is presenting the results on the use of plasma torches for aluminum reverberatory furnaces and one session at TMS2024 is devoted specifically to the additive manufacturing (3D Printing) industry:

@cusam Interesting to see Juan from PYR will be joined by a few folks from Constellium such as Louis Piquard. Constellium is a global leader in the development and manufacturing of high value-added aluminium products and solutions, and in aluminium recycling.

On his LinkedIn, he mentions (translated from French): https://www.linkedin.com/in/louis-piquard-6a9a02100/?locale=fr_FR

-Implement and test new emerging technologies to replace existing gas burners, for example hydrogen burner and electrolyzer or plasma torch (pre-design, drafting of specifications, test plan, drafting of technical reports)

- Build a simplified thermal modeling tool for aluminum melting furnaces to help pre-design future retrofit projects in the furnaces of the group's factories

Juan E. Salazar, Director of Product & Strategic Development - Aluminum, at PYR will be presenting on Decarbonization of Aluminum Reverberatory Furnaces: The Case of Plasma Melting:

Abstract Scope: 

In the context of decarbonization of aluminum cast houses, measures to reduce energy consumption for heating and fuel switching, with the associated impact of these actions on process emissions and the quality of the resulting metal, are on top of the list of aspects under evaluation by leading production companies and technology providers worldwide. Important options being compared for heating systems at this scale are oxy-gas, oxy-hydrogen, and electric plasma torches. In that context, this paper presents results of a test campaign launched with the aim to validate previous simulation models that pointed as plasma torches as a good replacement to fossil-fuel burners, including the effect on dross formation and magnesium loss in a 5000 series alloy, hence proving feasibility of the concept for both retrofit of existing furnaces and for new designs.

Direct electrification via plasma torches is the most efficient solution for decarbonizing high-temperature industrial processes. This applies to the production of aluminum, glass, cement, iron ore, steel and ceramics.

At PyroGenesis Canada Inc. / PyroGense Canada inc. we are addressing ~17% of the worlds fossil fuel use, primarily by replacing polluting gas burners across those sectors with our emissions-free electric plasma torches.

Plasma torches are an environmental technology first and foremost, but will ultimately usurp the status quo of fossil fuel combustion as they are capable of reducing operating costs and improving overall process efficiency. Environmental technologies that simultaneously reduce costs will naturally achieve widespread adoption first.

My colleague Juan E. Salazar, P.Eng. will be presenting our results in the application of plasma torches in aluminum melting furnaces at TMS 2024. If you are an aluminum producer interested in decarbonization and furnace efficiency improvement, we hope to see you there.

On that note, congratulations to Norsk Hydro and Hilde Merete Aasheim on the definitive step forward.
