H-Coal sour- and stripped-water characterization study
As part of an overall environmental evaluation of the H-Coal liquefaction process, sour water treatability studies were performed. These studies consisted of the listed major components. The studies indicate that H-Coal Sour Water can be successfully treated for reuse or for discharge to public waters. The first step in this program was to characterize the sour and stripped water. This characterization was performed during Run No. 8 when extensive samples were collected and analyzed. Samples of the process condensates and contaminated wash water, i.e. the sour water, and the H/sub 2/S and NH/sup 3/ stripped water were collected. This characterization study showed the wastewater to have high concentrations of organic and inorganic contaminants when Illinois No. 6 or Kentucky No. 9 coals were processed. The characterization study further confirmed the feasibility of a treatment scheme consisting of the treatment steps identified. The complete results of the characterization study are presented in this report.
