SELECTION OF A METHOD OF DETOXIFICATION OF OIL-CONTAINING SOILS

摘要

Based on the analytical hierarchic procedure developed by Saati, an evaluation has been made of the methods of detoxification (alternatives) of oil-containing soils (OCS), making a comparison of the weights of criteria in the absence of comprehensive information, to justify the selection of the most efficient and economically suitable method of detoxification of oil-containing soils. It turned out that the most efficient method of detoxification of oil-containing soils is chemical method, provided the hydrocarbons are extracted from them beforehand. Experiments have been conducted to determine the influence of oil hydrocarbons on the degree of extraction: amount of oil products, solvent/OCS ratio, process temperature, etc.
