1 Coal Ash Behavior in Reducing Environments (CABRE) III Freiberg Conference May 21 24, 24, 2012 Josh Stanislowski, Kevin Galbreath, Don McCollor, Bruce Dockter, Scott Tolbert, Jason Laumb, Bob Jensen, Tyler Curran, and Daniel Schwitalla 2012 University of North Dakota Energy & Environmental Research Center.
2 CABRE III Goal Create an advanced model for the prediction of slag and ash behavior in gasification systems. Utilize EERC small pilot-scale gasifiers for the development of the data. Distribute the model in the form of stand-alone software program. Pave the way for SABRE IV (Slag and Ash Behavior in Reducing Environments).
3 Sponsors
4 Work Plan Task 1 Feedstock Characterization Completed Task 2 Laboratory Evaluation of Ash Behavior Completed Task 3 Evaluation of Ash Behavior in Bench- and Pilot- Scale Systems Completed Task 4 Ash Impacts on Gas Cleanup and CO 2 Capture Completed Task 5 Modeling of Ash Behavior Completed Task 6 Model Verification Ongoing Task 7 Reporting Ongoing
5 Summary of CABRE III Program Status Characterization of the sponsor fuels is complete. Center lignite Falkirk lignite Illinois No. 6 Petroleum coke Each fuel has been tested in the entrained-flow gasifier (EFG). Falkirk lignite has been tested in the fluid-bed gasifier (FBG). Analyses of the samples from the EFG and FBG tests have been completed. The CABRE model was completed in spreadsheet form. Development of the model interface is complete. Testing of the model beta version is ongoing.

11 Development of CABRE III Model
12 Model Objectives Partitioning of slag and ash Viscosity models Slag properties Vanadium Mineral transformations Ash deposition Trace element partitioning Model inputs QEMSCAN analysis
13 Model Development Partitioning Partitioning is critical to the model. Determination of partitioning: Full-scale combustion cyclone slags. Full-scale gasifier ash. Bench-scale EFG tests. Bench-scale FBG tests. Partitioning not strongly linked to process conditions. Temperature affects partitioning most.
14 Viscosity Model Test Slag Composition Calculate Viscosity Indicators (5) Slag Database Composition Viscosity (100+ slags) Calculate Viscosity Indicators (5) Calculate Differences: Composition Viscosity Indicators
15 Viscosity Model Calculate Differences: Composition Viscosity Indicators Close Match in Composition? Yes Use Database Slag Viscosity (high confidence) No Close Match in Viscosity Indicators? Yes Use Database Slag Viscosity (some confidence) Use Riboud Viscosity Model No
16 Slag Viscosity Molten slag viscosity is measured in a rotating-bob viscometer.

34 Summary CABRE III model works to improve viscosity predictions by determining i the viscosity it of the slag produced d as opposed to using the coal ash chemistry. Viscosity is predicted using tables of experimental data when available, otherwise the Riboud model is used. The beta version of the user interface for CABRE III has been completed and beta testing is under way. This is only the beginning of program development. Many more samples and data sets are needed. Development of the SABRE IV project is under way.
