Carbon Capture Costs: FEED & pre-FEED Cost Reports

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.

Prairie State Generating Company is conducting a FEED study for a carbon capture facility on its 816 MWe Unit #2 in Illinois, using Mitsubishi Heavy Industries’ KM CDR Process™ with KS-21™ solvent. Designed to treat all flue gas from the unit, it would be the world’s largest post-combustion capture plant, compressing CO₂ for off-site sequestration. The project will leverage engineering support from Kiewit, Sargent & Lundy, and MHI.

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.
