Project performance targets for the selective agglomeration process were to achieve 85% or greater Btu recovery at 85% or greater pyritic sulfur rejection (PSR) on a run-of-mine (ROM) coal basis, while producing a final clean-coal product with an ash content of 6% or less which is handleable by conventional coal handling systems. Engineering development of selective agglomeration included: (1) Batch and continuous bench-scale precess development testing; (2) Continuous pilot-scale (3-t/h) component development testing to evaluate the adaptation and/or modification of existing unit operations for selective agglomeration; (3) Continuous pilot-scale (2-t/h) POC testing to optimize the selective agglomeration process and demonstrate precess reliability; (4) Vendor testing to evaluate pelletization and thermal drying precesses as applied to selective agglomeration; (5) Conceptual design of a commercial-scale (200-V/h) selective agglomeration facility; (6) Economic analysis of the selective agglomeration precess at a commercial (200-t/h) scale. The information obtained from the various modes of testing and analysis, particularly POC operations, resulted in a technical and economic design base sufficient to support construction and operation of a commercial plant.
