high-temperature thermal plasma Articles

  • Let’s talk plasma

    Usually when I attend a conference on behalf of Tetronics I am about the average age of the other delegates. Not this time. Suddenly, I am old enough to be the father of most of the other people here, because this is a university-based conference hosted by the University of Liverpool. Yes, this is the snappily-titled International Workshop on Plasmas for Energy and Environmental Applications, or ...

  • The use of thermal plasma technology for treating air pollution control residues

    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 ...

  • FAQ About Plasma Arc Gasfication Process from Plasma Waste Recycling, Inc (PWR)

    What is Municipal Solid Waste? Municipal solid waste (MSW)—more commonly known as trash or garbage—consists of everyday items such as product packaging, grass clippings, furniture, clothing, bottles, food scraps, newspapers, appliances, paint and batteries. It does not contain industrial, hazardous, or construction waste. Since 1980, the total annual volume of MSW generated in the U.S. has ...


  • Garbage to Gold: Breakthrough Technology Uses Plasma to Convert Waste to Useable Products

    A breakthrough technology that uses high-temperature thermal plasma to turn household garbage into a renewable energy source, scrap metal and mineral wool is attracting worldwide attention for Huntsville-based Plasma Waste Recycling. […]  The PWR process doesn"t involve combustion, but a gasification process that is ...


  • 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 ...

  • Degradation kinetics of organic dyes in water by high voltage atmospheric air and modified air cold plasma

    High voltage atmospheric cold plasma (HVACP) is a novel, non-thermal technology which has shown potential for degradation of various toxic components in wastewater. In this study, HVACP was used to examine the degradation kinetics of methyl red, crystal violet and fast green FCF dyes. HVACP discharge was found to be a source of reactive nitrogen and oxygen species. High voltage application ...

  • Recovery of sillimanite from beach sand of Chhatrapur, Orissa, India and its thermal treatment for refractory application

    Beach sands of Chhatrapur, Orissa, India comprise about 18% of heavy minerals, mixed with light minerals like quartz and feldspar. Sillimanite, which has refractory applications, accounts for 8% of these heavy minerals. Sillimanite was separated from garnet, monazite, zircon, rutile, ilmenite, magnetite, hematite and pseudo-rutile by combination of spiral, Wet High-Intensity Magnetic Separation ...

  • Characteristics of rotating arc for CF4 removal

    Characteristics of CF4 treatment process with a rotating arc are investigated under different thermal and non-thermal plasma conditions. To generate high temperature or non-thermal plasma conditions, a rotating arc reactor is operated with various operating conditions, which are species of carrier gases, flow rates, and input power. Test results reveal that that high temperature conditions caused ...

  • Synthesis of vertically aligned carbon nanotubes and diamond films on Cu substrates for use in high-power electronic devices

    Currently, most of the vertically aligned carbon nanotubes (VA-CNTs) and diamond films are mainly synthesised on flat silicon (Si) substrate. However, to achieve thermal dissipation in high-power electronic devices (HPEDs), the VA-CNTs and diamond films need to be attached to thermal dissipation metal substrates (like Cu, Ag, Al, etc.). In this paper, the fabrication process of the VA-CNTs and ...

  • Physico-chemical properties of SiOXNY thin films

    The physico-chemical properties of silicon oxynitride (SiOXNY) thin films deposited by plasma enhanced chemical vapour deposition technique (PECVD) from a mixture of SiH4, NH3, N2O and N2 have been studied. The N2O flow rate was varied from 0 to 75 standard cubic centimetres per minute (sccm). When the oxygen content in the plasma is increased, the deposit composition changed from SiNx to SiOXNY. ...

    Untitled Document EXECUTIVE SUMMARY This document provides state-of-the-practice information on off-gas treatment technologies for soil vapor extraction ...

  • Time to address the air pollution control residue problem

    The incineration of municipal solid waste is gaining increasing importance in the UK, especially as the burning of waste can be used to generate energy, providing a more sustainable solution to our waste problem by diverting it from landfill sites. An issue with incineration is that some of our waste contains hazardous chemicals such as chlorine and lead which are volatilised during the process. ...

  • The Spectrex particle counter used in study of pharmaceutical glass delamination.

    Delamination, or the generation of glass flakes in vials used to contain parenteral drug products, continues to be a persistent problem in the pharmaceutical industry. To understand all of the factors that might contribute to delamination, a statistical design of experiments was implemented to describe this loss of chemical integrity for glass vials. Phase I of this study focused on the effects ...

  • Electronic Waste: The Rich Resource in the Urban Mine

    Forgetting your mobile phone can be a real pain, playing on your mind during the day. Then as you think you can feel your phone vibrating in your pocket and you come to realise how dependent we are on our gadgets. Electrical equipment has changed our lives completely and we rely on phones, microwaves, TVs, kettles, computers to keep us informed, entertained and even alive. It is hard to imagine ...

  • The Trouble with Asbestos Disposal

    Hailed as a miracle mineral because of its superior fire resistance and tensile strength, asbestos was installed abundantly into our built environment for over 200 years. However, once it was established that this undeniably useful resource was a dangerous carcinogen, Australia and many other countries enacted strict regulations for handling asbestos and asbestos containing material (ACM). There ...
