2H4O) is produced by catalytic oxidation of E (C2H4) but competes with an undesired combustion reaction: 2C2H4+02-2C2H4O C2H4+302-2CO2 + 2H₂O The reactor effluent is sent to a separation process that produces two streams: 1) the unreacted E and O and 2) the EO, water, and carbon dioxide products. The E and O are recycled and mixed with a fresh feed of E and O to form the reactor feed. Assume the reactor feed (not the recycle stream or fresh feed) contains 3 moles E per mole O and assume a basis of 100 mol/'s for the reactor feed.

Question
EO (C2H40) is produced by catalytic oxidation of E (C₂H4) but competes with an undesired combustion reaction: 2C2H4 + 02- + 2C2H4O C2H4 +302 → 2CO2 + 2H20 The reactor effluent is sent to a separation process that produces two streams: 1) the unreacted E and O and 2) the EO, water, and carbon dioxide products. The E and O are recycled and mixed with a fresh feed of E and O to form the reactor feed. Assume the reactor feed (not the recycle stream or fresh feed) contains 3 moles E per mole O and assume a basis of 100 mol/s for the reactor feed. If the single-pass conversion of ethylene is 21.4% and 92.0% of the E that reacts forms EO. Determine the required flow of ethylene in the fresh feed (ne1). n1 nε-ne1 no no1 100 De=75 no=25 n4 DE=NE4 non04 Reactor n2 nε=nE2 no-no2 nEO-NEO2 Separator n3 n=0 no=0 nEO-NEO3
