Physical cleaning of coal using perchloroethylene as heavy medium
- Univ. of Akron, OH (United States). Dept. of Chemical Engineering
Use of perchloroethylene solvent in the physical cleaning of finely crushed coal has been studied in a glass tube batch apparatus. The density of perchloroethylene makes it an ideal heavy medium for float/sink separation processes. Float/sink removal of pyrites and mineral matter has been studied to determine the effect of process variables. The effect of various parameters is studied, such as mean residence time, solvent-to-coal ratio, and heavy medium density. The density of the perchloroethylene solvent is varied using kerosene to study the effects of medium density. The test results are used to assess the effectiveness of perchloroethylene as a heavy medium for the removal of pyritic sulfur from the coal. The data is used to develop a model of the process for use in scale-up and plant studies.
