Processing of heavy high-viscosity oil mixtures from the eastern region of Ukraine: technological aspects

Abstract

The article presents an analysis of reserves and processing of heavy high-viscosity crude oils in Ukraine and the world. A study of the physicochemical properties of heavy high-viscosity oils from the Yablunivske field, Poltava region of Ukraine, taken from various wells was conducted. For further research in order to develop a basic manufacturing scheme for the processing of heavy high-viscosity oils, a mixture of heavy high-viscosity oils from the Yablunivske field was used in certain ratios and its physicochemical properties were determined. As a result of the vacuum distillation of a mixture of heavy high-viscosity oils, the following products were obtained: broad gasoline fraction (fraction boiled up to 2000C), broad diesel fraction (fraction 200–3600C) and the rest of the process (fraction >3600C). An analysis of the physicochemical properties of the prepared fractions was also carried out. It was established that the products obtained from the mixture of heavy high-viscosity oils of the Yablunivske field can be used as raw materials for the production of commercial gasoline and diesel fuels. The rest of the process can serve as raw materials for the production of road bitumen. According to the analysis of the physicochemical properties of the products obtained by vacuum distillation of a mixture of heavy high-viscosity oils, the basics of the processing technology of a mixture of heavy high-viscosity oils of the Yablunivske field were developed. In particular, a manufacturing scheme and a flow chart of the process were proposed, and the material balance was calculated.
