Carbon Capture Costs: FEED & pre-FEED Cost Reports

Dastur International Inc., with Cleveland-Cliffs Inc., is designing a carbon capture system for the 5 mtpa integrated steel plant in Burns Harbor, Indiana, to capture 50–70% of CO₂ emissions from blast furnace gas. The system will combine a gas flow distribution network, a specialized conditioning process, and ION Clean Energy’s solvent-based capture technology with 90–98% efficiency, with water-gas shift reactors enabling higher capture rates. Dastur will lead overall plant integration and engineering, while ION designs the capture island and Dastur Energy optimizes design and energy performance.

Scope starts with the receipt of natural gas and fuel gas mixture from the existing Plant 01 and Plant 09 source and terminates with hydrogen (H₂) at the required specification and conditions to be used as fuel in the existing SMR unit. High concentration CO₂ from the ATR is captured and H₂ production from the proposed facility will replace the fuel gas feed to the primary reformer for heating. The facility capacity is based on the heating duty required to replace the current fuel source. The scope for the study involves the new ATR unit and associated downstream shift, CO₂ capture, and syngas purification unit. The project scope also includes an ASU to supply oxygen to the ATR unit.

Bechtel National Inc., with the Electric Power Research Institute, is conducting a FEED study to retrofit Panda Power Funds’ 758 MWe natural gas combined cycle plant in Sherman, Texas, with a post-combustion CO₂ capture system. Using an open-access design and a conventional amine absorber-stripper system with a non-proprietary solvent such as MEA, the project targets CO₂ capture for enhanced oil recovery.
