It is the objective of the present project to further develop the triboelectrostatic separation (TES) process developed at the Federal Energy Technology Center and test the process at a proof-of-concept (POC) scale. This process has a distinct advantage over other coal cleaning processes in that it does not entail costly steps of dewatering. The POC-scale unit is to developed based on (1) the charge characteristics of coal and mineral matter that can be determined using the novel online tribocharge measuring device developed at Virginia Tech, and (2) the results obtained from bench-scale TES tests conducted on three different coals. At present, the project is at the stage of engineering design, which has three subtasks, Charger Tests, Separator Tests, and Final POC Design. Work accomplished during the current reporting period pertains to the first two subtasks
