INVESTIGATION OF THE PROCESS OF IRON EXTRACTION FROM OIL BY POLYFUNCTIONAL REAGENTS

Abstract. The article presents the results of a study of the purification of oil supplied to the Atyrau refinery from iron by extraction. Polyfunctional reagents 1 and 2 were used as extractants. Determination of the iron content in oil before and after extraction, as well as in the working extract solution, was carried out by inductively coupled plasma atomic emission spectrometry. An unstable iron content was found at various stages (sampling points) of the oil treatment process. The high efficiency of absorption of iron from oil by the polyfunctional reagent-2 (more than 85%) was determined. The iron-concentrated working solution-extract is a potential metal-containing raw material. A significant reduction in the iron content in oil before it is fed to the catalytic cracking unit will increase the life of expensive catalysts, which will positively affect the economic performance of the oil refining industry.
