Design and optimization of a 36 MT/day pilot plant for the removal of sulfur from coal using the perchloroethylene process
- Univ. of Akron, OH (United States)
Perchloroethylene solvent can be used for both the physical and chemical cleaning of high sulfur, finely crushed coals. Previous studies using bench-scale extractions have shown that perchloroethylene solvent can remove from 20% to 60% of the organic sulfur in many coals. Associated research using glass tube settlers has demonstrated the potential for using perchloroethylene as a heavy medium for the removal of pyrites and mineral matter using a float/sink process. Additionally, a mini-plot plant has been designed and fabricated to study the cleaning of coal using perchloroethylene in a continuous process. Data from the studies are used to develop models for the unit operations in the coal cleaning process. The models are then used to support the design of a 36 MT/day pilot plant planned for future construction. Studies are done using ASPEN to assess the optimal configuration for the 36 MT/day pilot plant unit operations and to evaluate overall plant efficiency.
