The change of operating mode of the nonisothermic pipeleine by changing its linear part operating regimes

Abstract

The factors having an effect on the operating mode of nonisothermic complex pipeline were analyzed. The
criteria for optimization of pipeline operating modes for pumping high-viscosity oil with heating were studied. The
calculation technique of optimization of operating modes of the complex nonisothermic oil pipeline based on the
delivery maximum performance was proposed. The software to perform multivariant calculations with application
of the above mentioned algorithm was developed. The various operating regimes of the linear part of the nobisothermic
oil pipeline Dolyna – Drohobych with connection of other pipeline sections serving as loopings and inserts
were studied. The multivariant calculations of operating parameters of oil pipeline Dolyna – Drohobych for
different operating regimes of its linear part were performed. The comparative analysis of oil delivery depending on
the linear part operating regime of pipeline Dolyna – Drohobych was conducted.
