25. Hydrogen gas is used to reduce Fe2O3(s) completely to metallic iron Fe(s) according to the reaction : Fe2O3(s)+3H2(g)2Fe(s)+3H2O(g) After the reactor, solid Fe(s) is taken away and all of the water content of reactor gas effluent is condensed and the unreacted hydrogen and inert is recycled. Fresh feed contains 1 mole \% impurity I and balance is H2. The stream entering the reactor contains 3.5%I in moles. If the ratio of recycle to fresh feed is 5:1 on molar basis (a)Calculate the flow rate and composition of purge stream by taking 100k-mol fresh feed (b)Calculate single-pass conversion of H2 (c) Calculate over-all conversion of H2 (d) Calculate the amount of fresh feed to reduce 6.25kmol/hFe2O3(s) completely
