摘要：With more countries adopting a net-zero carbon emission goal, low carbon has become the focus of the trans-formation of the petroleum industry. Improper operations of the crude oil transportation system, one of the primary energy consumers of oilfields, usually cause severe environmental problems. Following the life cycle assessment method and considering the special process characteristics of the crude oil transportation system, a detailed carbon footprint analysis was conducted from the design to the recycling phase to identify the key phase for carbon emission control. Combined with process modifications, a multi-objective operation optimization model constrained by thermal constraints and insertion oil was developed to reach economic and environmental goals. Then, the multi-objective mixed integer nonlinear programming model was turned into a mixed integer linear programming model by the piecewise linearization method and augmented epsilon-constraint method. The models were validated using a typical case. The carbon footprint analysis showed that the average CO2e emis-sions were 2.68 t CO2e/(104 km m3 center dot a) over the lifecycle, and the CO2e emissions during the operation phase were the highest (74.04%) among all phases. Moreover, the optimization model reduced the total cost and CO2e emissions by up to 18.72% and 16.97%. Additionally, sensitivity analysis revealed that the optimal operation scheme was highly sensitive to the crude oil price and transportation volume. The total CO2e emissions per unit volume exhibited a concave trend as the transportation volume increased, indicating the existence of an optimal transportation volume that achieved the lowest emissions. The study captured the weak points of carbon emissions over the lifecycle and tapped into potential CO2 emission reduction, providing a reference for the design and operation of the future pipeline system.
