Development of a model of the optimal temperature mode of the main gas pipeline operation

The influence of the ambient air temperature on changes in parameters and thermophysical characteristics gas pumped through underground pipeline was investigated. This done because there are no scientifically sound recommendations for optimal after coolers at compressor station. presence site inversion heat exchange between soil – a change direction along length revealed. It proved that above surface should be substituted into formula calculating stations. made it possible to determine quantitative hydraulic pipe length, particular, density, viscosity, capacity, flow regime. is shown during year leads pressure end section up 0.15 MPa. A by 10 °С approximately 5 °С. Analytical studies develop practical power-saving operation determined optimum cooler outlet will which point coincides with location subsequent how control cooling coolers. In shutting down one several operating devices changing speed fan drive. developed make quickly regulate mode power consumption system compression
