Q#1 GATE CH 2022 NAT +2 marks -0 marks

Consider the process flowsheet in the figure. An irreversible liquid-phase reaction 𝐴 → 𝐵 (reaction rate −𝑟A = 164 𝑥A kmol m-3 h-1) occurs in a 1 m3 continuous stirred tank reactor (CSTR), where 𝑥A is the mole fraction of 𝐴. A small amount of inert, 𝐼, is added to the reactor. The reactor effluent is separated in a perfect splitter to recover pure 𝐵 product down the bottoms and a 𝐵-free distillate. A fraction of the

distillate is purged and the rest is recycled back to the reactor. At a particular steady state, the product rate is 100 kmol h-1, the recycle rate is 200 kmol h-1 and the purge rate is 10 kmol h-1. Given the above information, the inert feed rate into the process is ____________ kmol h-1 (rounded off to two decimal places).
