SULPHATE REMOVAL RESULTS USING BARIUM-CARBONATE AND THEIR ANALYSIS FOR REACTOR SYNTHESIS

摘要

The reaction rate of sulphate removal from acid mine drainage using barium carbonate was studied for various pH, calcium concentration, and BaCO_3/SO_4~(2-) feed ratios using batch studies. Process synthesis concepts were used to investigate the interaction between the optimum regions for reactor operation and the experimental results. The effect of various process objectives on the optimal operating region was also investigated, and its implication for the process design and further experimental program was considered.
