Behavior of Oil – Aqueous Solution Systems in Rotating Coil Column

Alexander V. Soin, Natalya S. Musina and Tatyana A. Maryutina

Behavior of oil-aqueous solution systems used for oil analysis in rotating coil column (RCC) has been studied. An RCC can be used as effective tool for pre-concentration and isolation of trace metals from crude oil and oil products into acidic solutions. An oil sample is continuously pumped through column as a mobile phase whereas an aqueous acidic solution is retained in the column as a liquid stationary phase. The main dependences of the stationary phase retention on construction and operating parameters as well as on the physicochemical properties have been investigated. Optimal values of density and viscosity of crude oil and oil products that could be analyzed with an RCC were estimated. Theoretical dependences of the stationary phase retention on density and viscosity differences between stationary and mobile phases were obtained. These studies allow predicting the retention of the different oil/oil product-aqueous solution systems in an RCC.
