The simulation program developed by the specialists of the center is designed to simulate stationary modes of the object operation for compression, drying and low-temperature separation of associated petroleum and natural gases. Account is taken of changes in external and internal working conditions, including different equipment operating modes, gas composition. The program allows you to simulate the operation of the object for the design, current and future modes in different seasons of the year. The software product includes a complex of system elements mathematical models in digital form (compressors, turbo-expander units, heat exchangers, separators, shut-off and control valves, dehumidifiers, pipelines), combined into a single digital object-a digital twin.
