QUALITATIVE ASSESSMENT OF HEAVY OIL RESIDUES AS POTENTIAL RAW MATERIALS OF DELAYED COKING PLANTS

The need to increase the depth of processing of petroleum and hydrocarbon-containing raw materials entails the need for qualified processing of residual products in order to use them more efficiently. This paper shows the role of the delayed coking unit in the processing of heavy oil residues and the deepening of oil refining, as well as the state of the global and Russian market for coke production and consumption. The analysis of various heavy oil residues according to the initial physico-chemical characteristics is carried out. The material balances of coking at the laboratory installation of both individual heavy oil residues and raw mixtures have been compiled. Graphical dependences of the output of coking products on the ratio of the initial components of raw materials are established and constructed. A number of promising areas of research for further improvement of the process are identified. The obtained data can be used in production planning in order to select the optimal composition of the raw material pool, the raw materials of the refinery as a whole, and the quality requirements of the products obtained.
