Abstract

Enhanced oil recovery schemes involve the transportation of large volumes of carbon dioxide from the capture source to the utilisation site. This research presents the possibilities of carbon dioxide transport using pipeline from the selected emission point to the oil reservoir located in Poland where greenhouse gas can be used as injecting fluid to improve oil production. In the first step, the different CO₂ thermodynamic states are analyzed. For the design purpose, length, operating pressures and flow rates are determined, then pipeline diameter is calculated. Furthermore, the pipeline transmission schemes for CO₂ transport are proposed. The study revealed, that the large amount of CO₂ produced at source power plant can be transported to the oilfield site more efficiently when CO₂ is converted into the liquid state. As a result, the smaller pipeline diameter can be applied for the transmission. Moreover, temperature decrease is observed when CO₂ is transported in gaseous state and temperature increase is present when CO₂ is in the liquefied state.
