A computer system for developing digital information models of oil recycling processes

The paper highlights main general characteristics of the secondary oil refining processes. It proposes a generalized information description of the secondary oil refining processes as the objects of design and management. It also considered the prerequisites for creating and experience of using digital information models in the field of oil refining on the example of Russian companies. The authors propose a functional structure of a computer system for designing digital information models of oil recycling facilities and a set of tools including information, mathematical support and software. The latter allow, according to the design specification, developing a digital information model that meets the requirements of the technical specification for performance, energy efficiency, quality of a digital information model – the model adequacy, the level of detail, information content, the model economy. There is the structure of information, mathematical and software in the paper. Information support is a set of various databases: characteristics of raw materials and catalysts, characteristics of the main technological equipment and pipeline parts, design standards. Mathematical support is a library of mathematical models of oil recycling processes including models of the kinetics of chemical reactions, heat exchange processes and hydrodynamics. Software is a set of software environments, both author's developments and existing software used at certain design stages. The proposed structure of the computer system is flexible and applicable for all types of oil recycling processes; the modular principle of architecture construction allows building reconfigurable in-formation and mathematical support for various types of oil refining processes. The computer system has been tested on the example of catalytic cracking and isomerization processes.
