The transport of copper ion through a hollow fiber renewal liquid membrane was studied with LIX984N as the carrier
kerosene as the diluent and H2SO4 as the stripping. The experiments were conducted as functions of pressure difference
copper concentration in feed and stripping solutions
flow rate of both sides
operation mode
effective length of the hollow fibers module
etc. The results showed that the pressure difference between shell side and lumen side fluid had little influence on the mass transfer performance of the hollow fiber renewal liquid membrane process. The mass transfer flux increased with the increasing copper concentration in the feed solution. The copper concentration in the stripping solution had almost no influence on the mass transfer. The mass transfer flux increased with the increasing flow rate of feed phase on the shell side
while the flow rate of stripping phase on the lumen side had slight influence on the mass transfer. The effect of both operation modes of countercurrent and cocurrent flow on the mass transfer was slight. The average mass transfer flux per area decreased with the increasing effective length of hollow fibers.
