【 摘 要 】

GranuFlow setup tests were performed at Edison Mission Energy's Homer City Coal Processing (HCCP) Plant. An asphalt emulsion (CCB as supplied by Asphalt Materials Inc.) was added to the plant's froth flotation concentrate stream at dosages ranging from 3.5% to 5.5%. Baseline tests (no emulsion added) were conducted immediately prior to and after each emulsion test. For each test, samples were collected around a single screen bowl centrifuge, including the centrifuge feed, filter cake product, main effluent, and screen drain effluent. A total of 12 tests were conducted, and each sample analyzed for moisture (percent solids), ash, sulfur, heating value (Btu/lb), and size consist.
