Plasma Waste Treatment Process
Plasma pyrolysis is used to safely treat various types of waste in a furnace or in a reactor. The plasma pyrolysis process is the thermal degradation of organic substance in the absence of air (oxygen) by means of plasma energy. As a result of this process occur dissociation molecules of organic matter (waste) and the formation of syngas and inert inorganic residue (slag). The main element of plasma technology is a plasma arc torch. A plasma torch uses gas or steam and metal electrodes (copper, tungsten, hafnium, zirconium, etc.) to create plasma, which is an ionized gas. The temperature of the plasma torch can be in the range
3 000-6 000°C; at these temperatures molecular bonds break down through a process called molecular dissociation, to create basic elements of materials – atoms.
Plasma processing of waste is an ecologically clean process. The lack of oxygen and high temperature in a reactor prevent the main elements of gas from forming toxic compounds, such as furans, dioxins, NOx, or sulfur dioxide. Extensive filtration removes inorganic residue (ash) and gaseous pollutants (NO, HCl, H2S, etc.) and allows the production of ecologically clean synthetic gas. The gaseous compounds do not contain any phenols or complex hydrocarbons. The circulating water in these filtering systems has removed the hazardous substances and must be cleaned.
Synthetic gas it is used basically for reception of electric energy. Gaseous pollutants are converted to valuable chemical products. Inert slag could be granulated and subsequently used in construction. Metal could be used for production of alloys, etc.
