Investigation of the effect of electrophysical parameters of the high-voltage short-pulse electrohydraulic discharge system and a nanocomposite catalyst on oil sludge destruction

Abstract

This paper presents the results of a study on oil sludge processing using high-voltage short-pulse electrohydraulic discharge. The influence of key parameters, such as discharge voltage, capacitor bank capacitance, processing time, electrode gap, and catalyst concentration, on the yield of light and medium petroleum fractions is analyzed. Experiments have shown that the optimal conditions for achieving the maximum fraction yield (up to 36.4%) are: a processing time of 6 minutes, an electrode gap of 10 mm, a capacitor bank capacitance of 0.125 μF, and a nanocomposite catalyst concentration of 1%. It has been established that the use of a catalyst enhances the destruction of high-molecular compounds, while optimization of the electrophysical parameters improves the energy efficiency of the process. The obtained results can be used to develop energy-efficient technologies for oil waste disposal.
