Babcock & Wilcox Power Generation Group (B&W) is developing the coal direct chemical looping (CDCL) process. The CDCL process consists of a unique moving bed reactor - the reducer - where pulverized coal is fully converted using iron-based oxygen carriers. The oxygen carrier is reduced from Fe2O3 to FeO/Fe and the flue gas is a concentrated stream of CO2 that is available for storage or beneficial use. The reduced FeO/Fe is oxidized to Fe2O3 using air in the combustor, liberating heat to produce steam for a supercritical Rankine cycle. The unique reactor design and reaction pathway of the CDCL process allows for retrofit, repowering, and/or Greenfield installation.
The overall project objective is to validate the CDCL process application for power generation through engineering system and economic analysis. Leveraging the extensive laboratory work completed by Ohio State University, the project will require minimal laboratory testing under the Phase I effort to complete the required engineering system and economic analysis. Specific objectives include: 1) Perform limited laboratory analysis to support the design of a full-scale system such as feed point spacing, particle attrition and deactivation; 2) Determine the corresponding cost of electricity for the proposed commercial design; 3) Determine the technical gaps separating the current CDCL technology and a commercial product; and 4) Develop a Phase II application including a budgetary cost for a pilot-scale system suitable to address the identified technology gaps.
