A scientific study was undertaken by Ashland Synthetic Fuels, Inc., to evaluate the cleaning efficiency of work clothing from the H-Coal Pilot Plant by a commercial laundry facility. Laundry process conditions for cleaning clothes were determined, and procedures were developed for laboratory analysis to detect coal liquefaction heavy distillate in work clothing and laundry wastewater. Laboratory testing and longwave ultraviolet light were used to monitor for skin contamination from recycled work clothing. Laboratory studies with spiked, unwashed cloth swatches showed a heavy distillate recovery efficiency of 86%. The laundry process was found to remove 98% of heavy distillate from spiked, washed cloth swatches. Low levels of heavy distillate and three polynuclear aromatic hydrocarbons were found in laundry wastewater, recycled work shirts and uncleaned T-shirts worn in process areas. Hydrocarbon material content in wastewater can be satisfactorily treated by process wastewater treatment units at synfuels facilities. There were data to suggest that process material accumulates in recycled work shirts (outer clothing) to about three times the level in new control shirts, but this accumulation was not noted in T-shirts (underclothing). Although residual process material was found in work shirts and gloves after cleaning, skin fluorescence monitoring with ultraviolet light indicates that skin contamination from contact with recycled gloves and work shirts is not occurring.
