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.

Linde Inc., with Linde Engineering Americas and BASF, is conducting an initial engineering design for a 3,500 tonnes/day CO₂ capture plant using Linde-BASF’s advanced aqueous amine technology at a Linde-owned steam methane reforming facility. The project will define integration options, establish project requirements, optimize process design, and develop engineering, cost, and schedule packages. BASF will provide the technology design, LEA will deliver detailed engineering and constructability assessments, and Linde will lead techno-economic, environmental, and safety analyses in coordination with the SMR plant operators.

The University of Texas at Austin, with AECOM Technical Services and Trimeric Corporation, is conducting a FEED study for the Piperazine Advanced Stripper (PZAS) CO₂ capture process at Golden Spread Electric Cooperative’s Mustang Station in Denver City, Texas. Designed for two GE gas turbines with HRSGs and a steam turbine totaling 464 MWe, the PZAS process uses 30 wt% piperazine for higher efficiency, solvent stability, smaller absorber size, and cost savings compared to conventional amine systems. The project will deliver a 30–60% complete design package and a capital cost estimate with ±15% accuracy.
