Most chemical plants have their own utility systems (UtSys) to produce utilities (e.g., steam, electricity, water) required for manufacturing chemical products, and the UtSy discharges a considerable amount of flue gases. A monoethanolamine (MEA) based CO2 capture system (CCSy) is a promising solution to separate CO2 from the flue gases, but it can lead to a loss in utility generation by the UtSy, because of utility requirements for recovering the MEA solvent. A technoeconomic feasibility study to deploy CCSy at an existing UtSy as an integrated process should be performed for chemical plants. Thus, we design three process integration configurations to combine the UtSy and CCSy and then develop each process optimization model. Lastly, our technoeconomic analysis determines the one among three configurations that minimizes the total cost of configurations.
