METHOD OF PROCESSING WASTES OF PETROLEUM PRODUCTS AT HIGH CONTENT OF MINERAL SEDIMENTS Russian patent published in 2002 - IPC

FIELD: utilization of ground contaminated with petroleum products, and mineral sediments from mazut and oil storages. SUBSTANCE: proposed method consists in delivery of wastes together with solid fuel and air to combustion chamber; air is supplied in excess for conducting combustion reactions in continuous burning process to final gaseous products and solid mineral residue; solid residue is continuously removed from reaction zone; combustion reactions of wastes and fuel are carried out in gas permeable volume; combustion reactions of volatile components of wastes and fuel are conducted in free volume of combustion chamber which embraces coaxially volume with wastes and fuel and is communicated with it through common gas permeable perforated wall. EFFECT: possibility of ensuring self-distribution of air in combustion zone in required amount; enhanced degree of filtration in fuel mass; complete combustion of coke and after-burning of gases; continuity of combustion process to final combustion products. 7 cl, 1 dwg
