The Thermal Treatment of Hazardous Waste Materials Using Plasma Arc Technology
نویسندگان
چکیده
The use of plasma arc technologies, especially in the treatment of hazardous wastes, is set to expand. The technology is intermediate within the waste management hierarchy and is characterised as an Advanced Conversion Technique (ACT) with Best Available Technique (BAT) attributes. Adoption is driven by the increasing stringency of environmental regulations, the requirement for efficient resource utilisation, the responsibility of original equipment manufacturers (OEMs) for product life cycle impact and the reducing capacity of traditional disposal mechanisms. Within this industrial climate plasma technology is set to become an important component of sustainable waste management solutions. Tetronics’ technology is mature and has been successfully employed in a range of commercial-scale environmental applications. This paper reviews recent developments of Tetronics’ technology for the treatment of Asbestos Containing Material. Operational results obtained from a pilot scale plasma arc system are presented along with material properties and ecological performance data.

Demonstration plasma gasification/vitrification system for effective hazardous waste treatment.
Plasma gasification/vitrification is a technologically advanced and environmentally friendly method of disposing of waste, converting it to commercially usable by-products. This process is a drastic non-incineration thermal process, which uses extremely high temperatures in an oxygen-starved environment to completely decompose input waste material into very simple molecules. The intense and ver...

Waste water treatment reservoirs are contaminated with many hazardous chemicals and acids. Reservoirs typically comprise concrete and reinforcement steel bars, and the main elements responsible for their deterioration are hazardous chemicals, acids, and ozone. Currently, a variety of techniques are being used to protect reservoirs from exposure to these elements. The most widely used techniques...
متن کاملRf Thermal Plasma Vitrification of Incinerator Bottom and Fly Ashes with Waste Glasses from Fluorescent Lamps
Thermal plasma vitrification is a successfully used technology to treat and recycle hazardous wastes. High plasma temperatures enable to destroy complex molecules and to encapsulate the toxic elements in a non-leaching glass or ceramic matrix, obtaining nonhazardous wastes with large volume reductions. In this work, hazardous incinerator residues (bottom and fly ashes) have been treated by mean...

Medical establishments play important roles in different activities by using of modern technology to serve the humans and the environment through different departments in the establishment and its firms. Medical wastes are considered as a hazardous waste because they contain toxic materials, infectious, or non-infectious wastes and they are considered as a hazard to millions of patients, health...
متن کاملEfficient, Modular Microwave Plasma Torch for Thermal Treatment
A high-efficiency and high-power atmospheric pressure plasma torch has been operated in air and nitrogen by modularly combining two 2.54 GHz microwave plasma sources. Each modular plasma device uses a shorted waveguide within which the plasma is sustained. They are arranged in series so the second torch adds all its power to the output of the first torch to produce one high power flame. Total m...
