From an environmental point of view

 

The outstanding advantages compared to all methods currently offered on the market can be summarized as follows.


COMPARISON OF TECHNOLOGIES

 

Mineralisation by quasi-pyrolysis Pyro-Kat Traditional incineration plant
This method uses the technique of quasi-pyrolysis and gasification. Mineralisation takes place in the temperature that ranges from 300 to 600 degrees Celsius. The final product of this process is a mineral which is nonhazardous waste as well as organic gas CxHy and CO – both fully oxidized to CO2 and H2O catalytically. This technology uses thermal transformation of waste during the process of incineration which takes place in the temperature ranging from 850 to2500 degrees Celsius. This method produces large amounts of toxic gas.
Types of waste to be neutralized
All solid, semi-solid and liquid organic waste, regardless of their calorific value, content of toxic and oil compounds, ash, moisture content and size. Hazardous waste can be also neutralized to an inert mineral which eliminates the necessity of using hazardous waste landfills. Extended assortment of waste as long as: calorific value is high, content of moisture, chloride, ashes and sulphur is low. There are some limitations as far as size and packaging are concerned. It is impossible to incinerate waste: which has low calorific value, metalliferous, liquid, with high content of ash, chloride and/or sulphur, concentrated acids and alkalis.
Energy consumption
This method is very economical as it is very low energy consuming. It is also possible to recover thermal and electric energy which is produced during the process – renewable energy. This method is expensive as energy consumption is very high. It is also necessary to use expensive monitoring devices. Fast material consumption is one of the factors causing cost increase.
Waste toxicity
The final product of this process is a mineral which is nonhazardous waste as well as organic gas CxHy and CO – both fully oxidized to CO2 and H2O catalytically.(TOC<0,5%) This method produces large amounts of toxic gas.
Conformity with the norms concerning emission standards
Pyro–Kat technology enables to achieve purification of the post reaction gasses on the level of 50% of EU and Polish emission standards. CO2 emission is 20 times lower than in an analogical incineration plant.Pyro – Kat technology enables to achieve purification of the post reaction gasses on the level of 50% of EU and Polish emission standards.

The key benefits

  • Efficiency of the MCT process: Available heat energy after the catalyst relative to the energy content of the supplied waste approx. 85% to 95%.
  • Efficiency of electricity generation: Heat Exchanger + Steam Turbine + Generator ca. 42%.
  • The overall efficiency of the whole system (i.e. generated electrical energy relative to the energy content of the waste introduced) is approximately 36% to 40%.
  • Operational running time of the system units is on average 25 years (some of them are more than 30 years in continuous operation).
  • Very low operational, maintenance, and repair costs are guaranteed by extremely strong reliability (high product quality with decades of industry experience).
  • Return on Investment in most cases is calculated between 3 to 5 years.
  • Replacement of catalysts is in most cases (normal unit size) only necessary between 10 to 15 years with a guarantee of 5 years.
  • Total operating costs are significantly lower compared to other methods, technologies, systems and applications, due to the innovative technology and flexible infrastructure with decentralised installations, mobile units on trucks, reduced logistic costs, etc.
  • All our installations, which are producing clean exhaust gases and solid residues, are fulfilling the requirements of the EU directives and undercutting them by up to 200 times. Therefore they are meeting the most restrictive limits in Germany and California.
