 A process for making dodecene from 3 butene molecules is described as follows. Butene is produced elsewhere in the plant in a mixture with nitrogen gas. Butene is 20% of the feed stream by mass. The fresh feed is mixed with a recycle stream and fed to a reactor that operates at a 25% fractional conversion (fconversion). The effluent from the reactor is fed to a separator which recovers 95% of the octene and all the N2 in a product stream and sends the remainder into a recycle stream. The recycle stream is mixed with the fresh feed. What is the flow rate of butene and dodecene in the the recycle stream needed to produce 10 lb-mol/hr of dodecene? Solve this recycle problem by breaking the loop.
