Robust optimization design for CO 2 pipeline transportation systems

CO 2 pipeline transportation systems are the important link for the carbon capture, utilization and storage (CCUS) technology. A robust optimization method is applied to the cost design of the CO 2 pipeline transportation systems. The robust optimization model is established to solve the uncertainty optimization problem of the pipeline transportation systems, which makes the design more reasonable than the traditional one. The proposed approach properly allocates the inlet pressure, inner diameter, wall thickness and the number of inter-stage boosting pump stations, which decreases the CO 2 transportation cost. Compared with other optimization methods, it is verified that the robust optimization method has more suitability and provides security for the pipeline transportation systems.
