“…In general, plasma processes for treatment of liquid and gaseous wastes do not produce useful by-products. However, a laboratory study demonstrated the possibility of depositing diamond films from the by-products of simulants of hazardous waste such as CCl 4 and benzene [47][48][49]. These liquids were atomized with hydrogen gas and sprayed into the plasma jet formed by a 20 kW dc plasma torch with the addition of a small amount of water vapour.…”

“…PCB destruction tests using oxygen as the atomizing gas resulted in destruction and removal efficiencies exceeding 99.9998%. Changing the atomizing gas to hydrogen reduced the destruction efficiency but directing the plasma jet towards a water-cooled substrate resulted in the growth of diamond films at a rapid rate from the PCB-containing oil [49].…”

Plasma waste treatment has over the past decade become a more prominent technology because of the increasing problems with waste disposal and because of the realization of opportunities to generate valuable co-products. Plasma vitrification of hazardous slags has been a commercial technology for several years, and volume reduction of hazardous wastes using plasma processes is increasingly being used. Plasma gasification of wastes with low negative values has attracted interest as a source of energy and spawned process developments for treatment of even municipal solid wastes. Numerous technologies and approaches exist for plasma treatment of wastes. This review summarizes the approaches that have been developed, presents some of the basic physical principles, provides details of some specific processes and considers the advantages and disadvantages of thermal plasmas in waste treatment applications.

This paper reports on a simple analytical procedure used to demonstrate the technical feasibility of adaptive plasma-assisted incineration. APAI is a novel concept that addresses current difficulties in the treatment of hazardous organic waste. It features continual optimization of a plasma afterburner's operating conditions for cost-effective destruction of persistent contaminants under variable feed loads. Hence, on-line composition monitoring is a key element of the process. A diagnostic method was specifically developed for an experimental model system that required optical measurements from the jet of a 25–kW induction plasma torch. The method used photodiode array detection of visible emission from the Swan band system of C2 to track the destruction of organic compounds. This rapid, simple, and inexpensive procedure proved adequate for demonstration purposes.
