催化裂化装置碳排放优化研究OA

Aim to minimize carbon emissions while balancing product quality and economic benefits.A full-process model of the fluid catalytic cracking(FCC)unit was established using Petro-SIM.By combining sensi-tivity analysis with the IPOPT(Interior Point Optimizer)optimization algorithm,a synergistic control strategy was proposed,characterized by low reaction temperature,low equilibrium catalyst activity,low feedstock carbon residue,and high feedstock preheating temperature.The results indicated that lowering reaction temperature,e-quilibrium catalyst activity,and feedstock carbon residue,while increasing feedstock preheating temperature,effectively reduced carbon emissions under product quality and process constraints.Following optimization,the total carbon emissions of the unit decreased by 10.62%,and carbon emissions per unit of product value de-clined by 10.03%.These results demonstrate the synergistic optimization of carbon emissions and economic effi-ciency,providing a theoretical basis and practical technical pathway for the low-carbon operation of FCC units.
