The Electrochemical Method of Oil-Contaminated Soil Remediation

Abstract:

In the present article, the experimental research of electrochemical cleaning of oil-contaminated soil is provided. The decrease of oil concentration in the soil from 1100 mg/kg down to 250 mg/kg at the current density in the range from 22 A/m² to 174 A/m² during 90 minutes is shown. It has been established that there is the limit amount of charge required for effective cleaning, which amounted to 0.96·10⁷ coulombs per kilogram of oil. The electrodes placement variant for the proposed method realization in real conditions is described. It is shown that at a voltage between the electrodes about 18 V and the cleaning efficiency of 77% the energy consumption will be 173 MJ/kg of oil.
