The Tank Bottom Oily Sludge Characteristics Studying and Treating Processing Researching

Abstract:

The sediments in all kinds of containers in oily field ground processing system were called tank bottom oily sludge. In this paper, the characteristics of sludge were studied. The colloid and asphaltene can increase strength of the oily-water emulsion film which can lead to seriously oily emulsion. In view of this, the process of conditioning-ultrasonic demulsification-centrifugal separation treating tank bottom oily sludge was designed by studying the sludges physical and chemical characteristics. The process parameters were selected. The conditioning were that the dose of detergent was 600 ~ 800 mg/L; The ultrasound processing was that the temperature was 60°C, the ultrasound power was 12Kw and the running time was 25min; The centrifugal separation was that the temperature was 60°C, the dosing flocculant was 600mg/L and centrifuge rotating was 2200r/min. The oily containing in the sludge of centrifugal exports was less than 2% by using this process at the optimal parameters.
