A commercially available ASPEN PLUS simulation using a pipe model was employed to determine the maximum safe pipeline distances to subsequent booster stations as a function of carbon dioxide (CO2) inlet pressure, ambient temperature and ground level heat flux parameters under three conditions: isothermal, adiabatic and with account of heat transfer. In the paper, the CO2 working area was assumed to be either in the liquid or in the supercritical state and results for these two states were compared. The following power station data were used: a 900 MW pulverized coal-fired power plant with 90% of CO2 recovered (156.43 kg/s) and the monothanolamine absorption method for separating CO2 from flue gases. The results show that a subcooled liquid transport maximizes energy efficiency and minimizes the cost of CO2 transport over long distances under isothermal, adiabatic and heat transfer conditions. After CO2 is compressed and boosted to above 9 MPa, its temperature is usually higher than ambient temperature. The thermal insulation layer slows down the CO2 temperature decrease process, increasing the pressure drop in the pipeline. Therefore in Poland, considering the atmospheric conditions, the thermal insulation layer should not be laid on the external surface of the pipeline.

Artykuł przedstawia koncepcje dywersyfikacji dostaw ropy naftowej do Polski. Scharakteryzowany został rynek dostaw tego surowca do kraju. Określono czynniki wpływające na wielkość przewozów ropy naftowej. Opracowano scenariusze dostaw ropy do Polski transportem morskim i przesyłowym oraz zaproponowano koncepcje dywersyfikacji dostaw surowca do kraju. Stwierdzono, że należy poszukiwać nowych tanich dostawców oraz wykorzystywać istniejący potencjał przeładunkowy polskich terminali morskich.

The paper presents the concept of crude oil supply diversification to Poland. The crude oil supply routes to the country were characterized. The factors related to the volume of the crude oil transportation were defined. The scenarios of crude oil supply to Poland by maritime and pipeline transport were developed. The conception of oil supplies diversification to the country was proposed. It was found that it is neccessary to look for the new low-cost suppliers and to use existing handling potential of Polish seaports.
