Gas and chemical waste treatment

Plasma-Process3

The plasma system

  • Plasma reactor: decomposition of the waste by the plasma stream
  • Cooling system: rapid cooling (Quench system) of the output gaseous mixture. This prevents the formation of undesirable by-products such as dioxins and NOx
  • Main scrubbing system: additional cooling of the gaseous mixture from 450°C to 80°C and main absorption of the halogen acids by process water
  • Ecological scrubbing system: additional cleaning of the exit gas so that any emissions to the atmosphere are non-hazardous and meet environmental regulations

The plasma process

  • The waste stream is treated by the plasma stream generated in the reactor. The high temperature in the plasma field can be adjusted depending on the type of chemical waste
  • The extreme temperature instantaneously disintegrates the waste molecules, leaving only the constituent atoms. High temperature plasma is generated by initiating a powerful electrical discharge into air or other gas, such as nitrogen, argon and steam
  • The hot gas mixture undergoes a rapid cooling phase in order to prevent formation of non-desirable compounds such as dioxins, furans and NOx
  • Output products include water, CO2 and halogen acids (in the case of halogenated waste treatment). These products are fed into a scrubbing system, where they undergo absorption of the halogen acids and additional cooling
  • The gas stream is recovered by the ecological scrubbing system. The exit gas is clean so that any emissions to the atmosphere are non-hazardous and meet all environmental regulations

Applications

The plasma system is designed for the treatment of:

  • Hazardous organic waste
  • Toxic waste
  • Medical biochemical waste
  • Halogenated waste
  • Gaseous waste
  • Liquid and suspension waste
  • Industrial and laboratory solvent waste
  • PCBs

Emissions comply with international environmental standards.
