Study on Influencing Factors of Rapid Identification of Drainage Oil by Conductivity Method

Abstract:

Study on influencing factors of rapid identification of drainage oil by conductivity method through experimental, discuss the influence of different operating conditions on the determination results. The effects of oil/water ratio, oscillation time, temperature, and oil type on conductivity were explored. Measured water conductivity of different kinds of oil, analysed the change of the conductivity and the best operating conditions were elected. The results showed that under the condition of normal temperature, shocked the mixture for 30s, the oil/water ratio was 4:1 and subsided for 15 minutes,the conductivity of drainage oil,frying oil and edible oil were 72.7 us/cm34.3us/cm12.5us/cm. The conductivity was largest and the testing results was most sensitive.
