  • Large-scale synthesis of nanopowders by transferred arc thermal plasma

    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 ...

  • Plasma Arc Waste Destruction System (PAWDS) - A novel approach to waste elimination aboard ships

    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 ...

  • Treatment of ship sludge oil using a plasma arc waste Destruction system (PAWDS)

    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 ...

  • Plasma gasification: Harnessing the power of lightning

    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 ...


  • Fly Ash Treatment – Plasma Torches versus Graphite Electrodes

    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 ...

  • 25 Years of Success – Outokumpu Stainless DC Plasma Smelting Facility

    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 ...

  • Plasma gasification and vitrification of ash – conversion of ash into glass-like products and syngas

    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 ...

  • Techniques for processing industrial waste using arcplasma generated by the twelve-phase alternating current

    We have already presented an arc-discharging plasma generator, generally called a thermal plasma generator which is constructed by the six-phase alternating current power supply(Matsuura et al, 1994a, 1997). A more effective thermal plasma generator can construct by expanding this concept. As an example, this small power supply system has been presented in reference (Matsuura et al., 1994b). In ...

  • Duncan recyling & refining - Precious metal recovery from spent catalysts case study

    The Challenge Spent catalysts contain Precious Metals, specifically the Platinum Group Metals (PGMs) that are valuable as a result of their low natural abundance, unique properties as well as the complex and costly processes that are required for their extraction/refining from primary sources. Duncan Refining and Recycling's (DR2) President, David Nichols, made the decision to ...

  • Our HVOF equipment takes coating to another level in Scandinavia case study

    KMAB (Karlstad Metallisering AB) in Sweden was the first company in Europe to purchase our CJK5 HVOF equipment. KMAB is a company with tradition that has been working with thermal spraying since 1958. Besides thermal spraying, KMAB are also working with machining, balancing and teflon coatings. Today the company is using plasma, flame, arc spraying and HVOF in their daily work. The parts that ...

  • Recycling and Waste World - Turning difficult waste into a useful resource

    Swindon-based Tetronics specialises in a thermal processing system that treats hazardous waste at source. Geraldine Faulkner talks to CEO, Stephen Davies, to find out about the benefits the company’s plasma process can bring to waste management; especially when it comes to dealing with ‘difficult’ materials. David Cameron is not the only person who is encouraging engagement with ...

  • Feasibility analysis for biomass in cities, counties and facilities

    The commercial waste industry includes all those who collect waste from the simplest “collect waste and transport to a landfill” to the more complex “collect waste and process into re-usable components and energy.” This article will cover how we can collect material and fuel a clean energy system for our immediate future, while saving clean water and air. ...

  • Mitsubishi corporation - Spent Potliner (SPL) hazardous waste treatment case study

    The Challenge Spent Potliner (SPL) is generated in the primary production of aluminium and worldwide is estimated to rise at a rate of over 500,000 tonnes per year. The SPL waste contains concentrations of cyanide and fluoride and gives off noxious and flammable gases when in contact with moisture. Unless carefully handled, these contaminants readily "leach" into the surrounding soils and ...

  • Introduction to Iran Spiral Company

    Iran SPIRAL COMPANY (ISCO) was established in 1991 East of Isfahan in the Segzi Industrial Zone at km 52 of the Esfahan – Naein Road. The aim was manufacture and supply of spiral welded line pipes for oil, gas and water usage. FEATURES OF ISCO ·         Having two simultaneous production mills gives more flexibility and faster ...

  • WESPS continue to deliver

    Compliance with the increasingly stringent air pollution regulations of recent years is not the only reason forwardthinking industry leaders are adopting more sophisticated gas cleaning and air pollution control strategies. The desire to achieve higher performance efficiencies, control costs in a competitive marketplace, and stay ahead of the regulatory compliance curve is another driver of ...
