please help with below question Consider the following reactor-separator -recycle flowsheet for the process: The fresh feed to the process 132 kmol/h contains 45 mol% ethylene, 50 mol% oxygen and 5 mol% nitrogen. The feed is mixed with a recycle stream and the combined stream is fed to the reactor. The conversion in the reactor is 18%. The reactor effluent is sent to a separator where all the ethylene oxide is removed (assume a perfect separator). The unreacted ethylene, O2. and N2 leave the separator and are split into a purge stream and recycle stream. If the purge stream flow rate is 60 kmol/h, determine the composition (as a mol fraction) of N2 in the purge steam. Determine the composition of ethylene (mol fraction) in the purge. Calculate the production rate of ethylene oxide in kmol/h. Determine the flowrate of ethylene to the reactor (not fresh feed) in kmol/h. Calculate the flowrate of ethylene (kmol/h) in the recycle stream.
