Study on Sludge -Sump Oil Viscosity Reduction by Surface-Active Agents Emulsification

摘要

This paper studied the effect of temperature, single surface-active agent and anionic/non-ionic surface-active agents to the viscosity of sludge-sump oil, and ditermined the optimum process conditions by orthogonal experiment. The result showed that the viscosity of sludge-sump iol reduced with the increase of temperature when below 50°C, then the viscosity decreased slowly when the temperature is above 50°C. The optimum conditions obtained by orthogonal experiment were: OP-10 0.6%, sodium dodecyl benzene sulfonate (SDBS) 0.3% and water content 35%. The viscosity reduction rate was about 98.80%.
