P 2 . lodine is commerclally obtained by the reaction of seaweed with M n O 2 and H 2 S O 2 2 NaI

P2. lodine is commerclally obtained by the reaction of seaweed with MnO2 and H2SO2
2NaI+MnO3+2H2SO4Na3SO4+MnSO4+2H3O+l2
20% more H2SO4 is fed to the reactor. The mixture leaving the reactor is sent to a separator to obtain a product containing 54K2 and 46KH3O by mass. The waste stream taken from the separator contains H2O,MnSO4,Na4SO4 and inert substances. The unreacted Nal and H3SO4 are taken from the separator and fed back to the reactor. Considering that the seaweed contains 5%Nal,30%H2O and 65% inert substances by mass and the reaction occurs at a single pass conversion of 80%.
a) The amount of kgh2 obtained from I ton of seaweed,
b) The amount and mass composition of the waste stream,
c) The amount and mass composition of the recycle streism
