WPC Plasma Advantages WPC’s plasma torch technology, which has been in development for over 30 years, is a high efficiency process heating device designed to operate with minimal maintenance in an industrial environment. The WPC plasma torch provides an inherent level of flexibility over combustion burners as it allows control over temperature, independent of fuel or oxygen throughput in the process. In general, the greater the temperature difference between the heat source and the material to be heated, the faster it can be processed. The benefits of WPC plasma torches include:
Did you know? The largest plasma gasification facility in the world was developed by Hitachi Metals Ltd. in Utashinai, Japan using the WPC technology. This facility has been treating 200-280 tpd of MSW and auto shredder residue since early 2003.
Plasma gasification represents a clean and efficient option to manage waste in
an environmentally responsible manner. The WPC plasma gasification technology is
ideally suited to process waste such as Municipal Solid Waste, common
hazardous waste, industrial waste, chemical waste, sediment sludge and biomass.
As well as, it can also vitrify fly ash from incinerators and any other types of
ash. Converting waste into various energy outputs or power reduces our reliance
on the use of conventional fossil based fuels by using readily available waste.
Incineration Plasma Gasification Oxidation completed using excess air to form CO2 Gasification completed using partial oxidation and water shift reaction to form mainly H2 & CO Yields bottom ash requiring disposal in special landfills. Yields an inert vitreous slag suitable for aggregate use. Yields hazardous fly ash that requires alternate disposal or treatment. Fly ash combined with molten slag and rendered inert. Limited to steam cycle power generation with a typical thermal efficiency of 15% from input. Ability to run steam cycle, combined cycle or produce transportation fuels depending on configuration allowing for higher thermal efficiencies. In addition, WPC gasification offers the ability to sequester CO, H2 or CO2 for chemical industry use. Plasma gasification also offers a means of achieving the high temperatures required for the safe destruction of many hazardous and toxic wastes. Materials, such as PCBs, dioxins, DDT, furans, halogenated hydrocarbons, as well as military chemical agents, pose serious problems to the environment and to the public. Facilities employing a plasma process for the destruction of such materials have resulted in safe disposals with emissions below regulatory requirements. Plasma gasification of typical hazardous waste generates almost eight to ten times as much energy per unit of waste than the energy required to destroy the waste. As well, compared to conventional waste management strategies, plasma gasification is able to recover more energy from residual waste and also recycle all the solid by-products of the remaining residue.
