Plasma atomization is used in many applications, including 3D printing. First developed in 1998, this technique has risen to become the industry standard process for creating reactive metal powders suitable for 3D printing. Learn how plasma atomization works and why you need an oxygen monitor to stay safe with plasma atomization.  How Plasma Atomization Works ...

Beam–plasma systems (BPS) are known to be a great prospect for the surface modification of organic and inorganic materials. The present paper considers the plasma–assisted synthesis and deposition from the point of view of the hybrid materials production. Pilot setups in which the above processes occur in the electron–beam plasma (EBP) and combined plasma (CP) are described. The results of the ...

Reliability testing is a very important component of new engine development. Engineers need to fully understand and chart the engine lifetime performance under a variety of conditions before mass production may be considered. Many important performance data parameters are collected in real time through the many different types of sensors that are connected to the engine in the test cell and oil ...

Plasma gasification is both a high-tech solution to the problem of waste management and a source of renewable power. The technology has great potential, but can it move from the fringes to the mainstream? The name "plasma gasification" conjures up images of men in lab coats late at night, investigating a far-flung corner of science that is light years away from commercial readiness. In reality it ...

The Plasma Gasification and Vitrification of Ash (PGVA) system is a patented process that uses energy generated by plasma arcs along with the controlled addition of small amounts of air and steam to convert the organic portion of ash into a synthesis gas (gasification) and the inorganic portion into a glassy rock (vitrification). The vitrification of the ash’s inorganic portion ...

Abstract Plasma Resource Recovery (PRR) is a revolutionary technology that can treat virtually any type of waste by combining gasification with vitrification. Vitrification produces inert slag that can be used as a construction material. Gasification produces a fuel gas containing carbon monoxide (CO) and hydrogen (H2), used for cogeneration of electricity and steam. The plasma fired ...

The present work describes the preliminary results on large-scale synthesis and characterisation of copper (Cu) and aluminium nitride (AlN) nano powders by transferred arc thermal plasma technique. The transferred arc was used to vaporise the precursor materials (Cu, Al metal 99.9% pure). Nano particles are formed in the gas phase as a result of homogeneous nucleation. The vapours of Al were ...

Test results on Automobile Shredder Residue (ASR), or car fluff, demonstrated destruction efficiency and safe conversion to synthesis gas and a glass residue, in a plasma gasification system. The synthesis gas consists primarily of hydrogen and carbon monoxide in the range between 20 and 22 vol-% respectively, or 45 and 55 vol-% dry basis, when corrected for nitrogen. In dry reforming operation, ...

In order to prevent health risk from potential exposures to phthalates, a glow discharge plasma (GDP) process was applied for phthalate degradation in aqueous solution. The results revealed that the phthalate derivatives 4-hydroxyphthalic acid, 4-methylphthalic acid and 4-tert-butylphthalic anhydride could be degraded efficiently in GDP process (498 V, 0.2 A) with high removal efficiencies of ...

Abstract—For nearly two decades, interest in gas-phase pollution control has greatly increased, arising from a greater respect for the environment, more attention to the effects of pollution, and a larger body of regulations and laws. Nonthermal plasma (NTP) technology shows promise for destroying pollutants in gas streams and cleaning contaminated surfaces, using plasma-generated reactive ...

Plasma technology has some shortcomings, such as higher energy consumption and byproducts produced in the reaction process. However non-thermal plasma associated with catalyst can resolve these problems. Therefore this kind of technology was paied more and more attention to treat waste gas. A hybrid system comprising a non-thermal plasma reactor ...

Design is not just what is looks and feels like. Design is how it works. Between 1982 and 1987, British Steel (Outokumpu today) made extensive investigations into the treatment of steel dust. Their research was far and wide and covered off many various methods of recycling, including alternative to plasma technologies. But, in 1985, they engaged Tetronics International to carry out a ...

Energy from waste (EFW) is an exciting industry to be in right now in the UK. As pointed out by Euston Ling and Dr. Adam Read's article "The Shifting Landscape for Renewable Energy in the UK" {Waste Advantage Magazine, June 2011), the EFW capacity in the UK is set to grow strongly in the next 10 years, with some commentators predicting a three-fold increase in EFW capacity from the current 4 ...

Background Plasma generating devices have to be designed to tolerate incredibly harsh conditions during operation and in particular very high heat loads and temperatures around the arc. However, when used in the vitrification of highly chlorinated materials the challenge is even greater than in other applications. The combination of high ...

The Plasma Arc Waste Destruction System (PAWDS) uses plasma energy, with temperatures over 5,000 oC, to rapidly and efficiently destroy combustible waste aboard ships. PAWDS has proven itself to be a viable alternative to traditional incinerators. In September 2003, Carnival Cruise Lines were the first to install a PAWDS aboard their 2,056 passenger (plus 1,000 crew members) capacity, M/S ...

The Plasma Arc Waste Destruction system (PAWDS) uses a plasma torch to quickly gasify solid  waste on board ships. Developed under the support of the US Navy, this compact one deck system has been in commercial operation on board a cruise ship for more than three years. With the support of Carnival Cruise Lines and the National Research Council of Canada, the PAWDS was recently modified in ...

Instream flows of the rapidly urbanizing watersheds and estuaries of the Gulf of Mexico in Texas (USA) are increasingly dominated by reclaimed waters. Though ionizable pharmaceuticals have received increasing attention in freshwaters, many research questions remain unanswered, particularly in tidally influenced urban coastal systems, which experience significant spatiotemporal variability in ...

Abstract The disposal of Municipal Solid Waste (MSW) is an increasingly difficult challenge for communities. Advanced thermal treatment (ATT) technologies, such as Gasplasma®, have been specifically developed to effectively utilise wastes to generate clean electrical power. An added beneficial feature of this process is the conversion of ash-type materials in the MSW to ...

We have reported aluminium doped zinc oxide (AZO) film grown on sapphire substrate using dual–plasma–enhanced metal–organic chemical vapour deposition (DPEMOCVD) system. The crystalline quality, surface morphology, optical properties, and electrical characteristic of AZO film depend on the deposition temperature and Al content. The 185°C–deposited and 2.88 at%–Al–doped AZO film shows a strong ...
