Golianov (The Pipeline Transport Institute LLC, RF, Moscow), O.V. Chetvertkova (The Pipeline Transport Institute LLC, RF, Moscow)

The aim of this article is to justify the field of rational application of drag reducing additives (DRA) – DR technology and substantiation of the methodology for optimizing the technological modes of operation of the main oil pipeline taking into account the properties of the DRA in terms of energy and economic efficiency of the pumping process. A methodology for evaluating the effectiveness of the use of pumping technology with DRA, based on the fundamental principles of a methodology for quantifying the effectiveness of oil transportation, is proposed. The efficiency criterion is the ratio of the calculated pumping parameters to the actual values recorded by the standard means of the Dispatch Control and Pipeline Management System, which allows real-time identification of the components of the efficiency factor of the technological section of the main pipeline. Monitoring the components of the efficiency factor of the technological section of the main pipeline allows to identify reserves for reducing energy consumption in the main transport of oil and oil products, as well as to compare the performance indicators of various production facilities of Transneft with each other, taking into account the whole variety of design decisions of the technological section of the main pipeline: looping, inserts, discharges and pumping, tees, valves, etc. In the framework of the proposed performance criterion, the features of the technology of using DRA to shut off part of pumping units in order to save energy resources and to temporarily increase the pumping capacity in excess of the capacity of the existing oil pipeline are considered. It is shown that the cost of the agent for reducing hydraulic resistance (5-12 USD/kg) is a significant limiting factor for the widespread use of DR technology, which limits the appropriate concentration of additives to 10 ppm in terms of reducing operating costs for pumping (specific energy consumption and costs on DRA).
