Many chemical processes generate emissions of volatile compounds that need to be controlled. In the process shown in Figure P12.27, the exhaust of CO is eliminated by its separation from the reactor effluent and recycling of 100% of the CO generated in the reactor together with some reactant back to the reactor feed. Although the product is proprietary, information is provided that the feed stream contains 40% reactant, 50% inert, and 10% CO, and that on reaction 2 moles of reactant yield 2.5 moles of product. Conversion of reactant to product is only 73% on one pass through the reactor, and 90% overall. You arc asked to calculate the ratio of moles of recycle to moles of product. What do you discover is wrong with this problem? co 80% Reactant 20% Recycle Co Product Feed Product stream Inert Reactor Separator (gas) 4100 kg molhr Inert Reactant Reactant Figure P12.27
