COMPOSITION OF OIL PRODUCTS AND METHODS OF SEPARATION OF INDIVIDUAL SUBSTANCES

Abstract

The article examines the widespread use of chemical processes in the oil refining industry to obtain essential petroleum products and improve their quality. Currently, aromatic hydrocarbons are obtained from petroleum fractions included in the products of reforming and catalytic reforming, and from natural gas from pyrolysis waste - pyrolysis oil and by-products. The types of pyrolysis oils contained in secondary petroleum products, methods for their extraction, determination of composition and problems of their separation into separate parts are analyzed, optimal methods are identified. In addition to the classical method of separation and purification of organic substances, the advantages of using the extraction method for pure separation and analysis of compounds are described.
