Multistage counter-current extraction process with alternating extraction and stripping is proposed to increase mass-transfer rate and decrease the number of stages. Based on a theoretical analysis
extraction cascade computation was made for two systems-extraction of ferric ions with N
N-di (1-methylheptyl) acetyl amide (N503)
and extraction of H3PO4 with DBSO. The results of computation for the former system
when verified against experiment
showed that the extraction mass-transfer efficiency is notably higher than a common multistage counter-current process.
