Abstract:

In order to realize the recovery of oil sludge and reduce its production and the difficulty of final disposal, the conditioningthree phase separation method could be used for the quantitative reduction processing of oil sludge. The effects of agent type and dosage, heating temperature, centrifugal speed, centrifugal time on the reducing effect of oil sludge were studied in detail. Results showed the best agent combination was P-A(1%)+CPAM(1.5%). Heating temperature, centrifugal speed and centrifugal time should be no less than 80 ℃、4 000 r/min and 10 min. The solid content of sludge after separation could be more than 40%.

Key words: conditioning-three phase separation, reduction, oil sludge
