SOME PUMPING CHARACTERISTICS OF COAL CHAR SLURRIES

Some pumping characteristics of coal char slurries were studied with water, mineral oil, and a petroleum recycle oil as slurry media. Brookfield viscometer data showed that the viscosity of the slurries could be reduced by adding minus 325 char, and data obtained in a 1 in. dia model pipeline led to the prediction that pumping costs for a 50% by wt char-water slurry would be 0.16 cents/ton/mi, comparable with those of other commercial slurry pipelines. The recycle oil was used because of its resemblance to the product oil from the coal upgrading process being developed by the U.S. Bureau of Mines, Office of Coal Research under the COED (Char Oil Energy Development) project.
