COMPARISON OF TECHNOLOGIES

Mineralization by quasi-pyrolysis Pyro-Kat Traditional incineration plant
This method uses the technique of quasi-pyrolysis and gasification. Mineralization 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.
