After vacuum distillation, the used engine oil becomes a lubricant with a viscosity of around 30. Acid and alkali are added to facilitate sedimentation and removal of impurities, after which clay is used in a tank to raise the temperature to about 120 degrees; the mixture is stirred for one hour before being filtered. The color and acid value parameters are within acceptable limits, but the anti-emulsification parameter does not meet the requirements. Seeking advice: 1. What are the reasons behind the unsatisfactory anti-emulsification performance? 2. How can the process be modified to achieve satisfactory anti-emulsification properties?
