ELECTROPERSULFATE TREATMENT OF OIL PRODUCTION WASTE

Abstract

A study on the possibility of implementing electropersulfate treatment of waste from the oil industry has been conducted. The dynamics of the volt-ampere characteristics during the transmission of electric current through the soil containing reservoir water and oil, with the introduction of persulfate salt, has been studied.The experiment made it possible to give a preliminary assessment of the possibility of using electropersulfate cleaning. The fairly high rate of electrophysical and electrochemical processes is associated, among other things, with the ability of potassium persulfate to actively oxidize components in the treated environment. The presence of formation water in the soil, which increases the humidity and the amount of salts dissociated into ions, and accordingly increases the conductivity of the soil, can accelerate the process. In addition, the use of iron electrodes promotes the activation of potassium persulfate, as does an increase in soil temperature during electrical treatment. In general, the presented experience allowed us to conclude that soil purification by electrical cleaning using potassium persulfate is suitable. At the same time, an important task for future research is to determine the optimal parameters of the minimum reasonable (in terms of time, amount of charge passed through the medium, dose of introduced persulfate) treatment using electroactivated persulfate salts.
