Today, the most used material for the construction of pipeline systems, namely upstream, midstream and downstream, is steel. However, corrosion occurs in the operation of pipelines, which subsequently leads to accidents and pipeline shutdowns. Thus, field pipelines have the highest rate of pipeline failures due to corrosion (about 60-70%), main pipelines (25-50%), and distribution pipelines (about 4%). The main cause of internal corrosion is carbon dioxide corrosion, which becomes even more important in the context of decarbonisation and carbon neutrality. Both existing and prospective technologies for reducing CO2 emissions by capturing, gathering and disposing of them cannot be effectively achieved without solving the important task of ensuring reliable, safe pipeline transport of carbon dioxide. It is worth mentioning that regulatory requirements for the design and operation of pipeline CO2 transport facilities also do not currently exist. Among other things, polymeric materials resistant to aggressive media are not a solution due to the significant disadvantages and limitations of their application. In this context, the aim was to prepare a scientific and practical justification and feasibility study for the use of polymer and composite pipelines in existing pipeline systems across the whole world. As a result of the work, dependences of equivalent diameter of non-metallic oil and gas pipelines on diameter of steel pipelines and roughness of both pipelines have been received by analytical method, taking into account their identical hydraulic efficiency. The feasibility study of application of parallel non-metallic pipelines instead of one steel pipeline has been carried out. With the help of software package Schlumberger OLGA including MultiFlash the hydraulic losses along the length of 50 km of CO2 pipeline in liquid, supercritical and gaseous phases were calculated for the pipelines of various diameters. Corrosion rates in the pipeline during CO2 transportation were calculated in the PIPESIM software for the relevant pumping regimes. A substantiation of optimum thermal-hydraulic modes and corrosion risks of carbon dioxide pumping in pipeline systems of collection, main transport and distribution networks was carried out. Based on the work carried out, appropriate recommendations were given for the design and operation of CO2 pipelines.
