Reagent Encapsulation of Petroleum Residues with the Application of End Products of Technique as Marketable Output

Abstract

There was considered one from the most promising methods of petroleum residues detoxication – the method of reagent encapsulation. There were examined original characteristics of petroleum residues. There were defined elements, exceeding Maximum Permissible Concentration, Tentative Allowable Concentration for different soil types. There was offered use fly ash of CHPP as modifying additive to calcium oxide. Fly ash contains silicon and aluminum oxides that allows improving quality of obtained capsules. There were offered optimal proportion of reagents for effective detoxication of petroleum residues. There were examined characteristics of capsules, obtained during detoxication of petroleum residues. There was showed that with increasing of carbonization time adverse impact capsules on the environment is decreasing. On the basis of carrying out researches there was offered using obtained capsules as building materials and additives to potting soil. There were determined the main technical and physical characteristics of building materials on the base of obtained capsules.
