Project Description

Dastur International Inc., in coordination with Cleveland-Cliffs Inc., is conducting an initial engineering design of a carbon capture system to capture 50–70% of carbon dioxide (CO₂) emissions from the available blast furnace (BF) gas at Cleveland-Cliff’s 5 million tonnes per annum (mtpa) integrated steel plant in Burns Harbor, Indiana. The system will integrate a BF gas flow distribution system, a unique BF gas conditioning process, and ION Clean Energy, Inc.’s solvent-based state-of-the-art carbon capture technologies with proven capture efficiencies from 90–98%. In the base case, up to 50% of CO₂ can be captured from the available BF gas; to facilitate greater CO₂ capture, a compositional shift of BF gas is carried out using a combination of water-gas shift reactors. Dastur International, Inc. will undertake the overall design and engineering of the project, including integrating the carbon capture island with the existing plant, and conducting various studies and investigations related to the project. ION will design and engineer the carbon capture island for this study. Dastur Energy, Inc., affiliate of Dastur International, Inc., will contribute to the design optimization and energy engineering aspects of the project.

Project Benefits

Carbon dioxide capture from industrial facilities, such as ethanol plants, petroleum refineries, and chemical production plants, with emissions greater than 100,000 tonnes of CO₂/year, is critical for achieving reductions in CO₂ emissions. For industrial processes in which CO₂ emissions are not only a product of the combustion of fossil fuels, but also an unavoidable byproduct of an inherent chemical process, CO₂ capture and compression from both the power/heat production and the chemical processing parts of the facility is needed to achieve overall negative emissions. The completion of an initial engineering design and cost estimate for the installation of a CO₂ capture system at an existing industrial plant site allows for a full assessment of the costs and scalability of the system, mitigating the risk for commercial deployment. The resulting capital and operating costs derived from the engineering designs for commercial-scale industrial CO₂ capture systems will enable insights into technical issues to further reduce those costs.
