Software tools for planning and optimization of technological schemes of refineries

The purpose of this paper is to review the software for optimization (modernization) of petrochemical enterprises. Planning process touches upon almost all production stages from corporate level to optimization and finances (figure 1) and consists in coordination of activities of raw materials and reagents supply departments, product sales department, production departments of refinery. Coordination of interaction of different structural subdivisions of the enterprise is first of all connected with determination of the most economically profitable direction of enterprise development. For example, building the prospective scheme of development or upgrade of a refinery, as well as optimization of separate production processes, such as compounding of intermediate products, optimization of composition of marketable oil products, search for the best initial feedstock, optimization of power consumption and capacity utilization requires application of up-to-date tools of modeling and calculation for a great number of variables. The optimization process helps provide economic benchmarks for production adjustments.
