Research on Oily Sludge Treatment by Solvent Extraction
This paper present the optimum conditions for treating oily sludge with organic solvent extraction and surfactant solutions using the single factor experiment.Firstly,selecting petroleum ether (boiling range is 60-90℃) as the organic solvent,then selecting the mixture of sodium dodecyl benzene sulfonate and alkylphenol ether(OP-10) as surfactant agent to extract residual crude oil.Results obtained through experiments,the optimum parameters of petroleum ether were that ultrasonic reaction temperature was 55 ℃,ultrasonic intensity was 320W,ultrasonic extraction time was 5min,liquid/solid mass rate was 7.5,then under the optimum conditions,the residual oil rate was about 6%.While the optimum parameters of surfactant mixture were that the temperature was 55 ℃,ultrasonic intensity was still 320W,ultrasonic extraction time was 10min,liquid/solid mass rate was 15,under the optimum conditions,finally the residual oil rate was only about 1%.
