ABSTRACT Pyrolysis dissolves waste and also produces useful by-products. In this case, gas, liquid and solid phases are formed. Gas mixture containing tar, among other components. Water scrubbing technology is used for pyrolytic gas purification. The disadvantage of this technology is that tar components gradually accumulate in the water. Most exposed to this process the readily soluble light heterocyclic aromatic compounds of tar, as well as heavy polyaromatic compounds of tar. Some light aromatic tar compounds, the content of which is usually very high in the pyrolytic gas, are present in small amounts in the cooling and cleaning water. In the pyrolytic gas purification process, not only does the total amount of tar in the cooling and cleaning water increase, but also the ratio of the individual tar compounds to each other changes, especially the heaviest polyaromatic tar compounds accumulate, which leads to problems. further purification and use of the cooling and rinsing water itself. |
