Experimental demonstration, mathematical modelling and simulation of a technique for reducing
thermal energy consumption in the diaphragm cell process using a techno-economically viable process to
produce 73% wt. NaOH from electrolytic diaphragm cell catholytes of about 10% wt. NaOH was carried out
in this work. The technique completely eradicated the use of thermal energy in concentrating catholyte effluents
from about 10% wt. NaOH solution to 50% wt. NaOH solution. This resulted in a specific energy savings of
about 2.68×106 J/kg NaOH. The use of a spray dryer for increasing the concentration of 50% wt. NaOH
solution to 73% wt. NaOH solution further improved the energy savings compared to that of multiple effect
evaporators by 1.41×106 J/kg of solution, which corresponds to about 61.05% specific energy savings. The
deviation of all simulated results from experimental data was between -0.062 and +0.084, portraying a good
predictive tool for probing into the spray dryer operations. This work is expected to reduce considerably the
total energy consumption of the diaphragm cell process through process integration or new processing
methodology, with improved equipment designs.
