2C2H4+O22C2H4O An undesired competing combustion reaction takes back simultaneously in the reactor: 2C2H4+3O22CO2+2H2O The feed to the reactor (not the fresh feed to the process) contains ethylene (C2H4) and oxygen (O2) in a ratio of 3:1 (i.e. 3 mols of ethylene per mol oxygen present). The product stream from the reactor contains the unreacted reactants and all the products from the above reactions and is fed into a separating unit which separates the ethylene oxide (C2H4O) completely as a main product stream. The unreacted reactants are taken out as a recycle stream from the separating unit and mixed with the fresh feed to produce the feed to the reactor, while the remaining products (carbon dioxide and water) are taken out as a third stream from the separator and discarded. The single pass conversion of ethylene is 20%. For every 100 moles of ethylene consumed in the reactor, 90 moles of ethylene oxide is produced. Assume that the oxygen in this process is pure oxygen fed into the process with the ethylene in one stream. For a basis of 100mol/h flow of the reactor feed stream, calculate the following: Use either atomic specie bulance or extent of reaction method to answer this question. 3.1 Draw a detailed and fully labeled diagram for this process 3.2 Calculate the molar flowrates of the components in the reactor product stream (10) 3.3 What is the molar flowrate of ethylene oxide leaving the process? 3.4 Calculate the molar flowrates of the components in the fresh feed to the steam 3.5 Calculate the overall conversion of ethylene (2) 3.6 If the oxygen was fed into the process from an air stream, explain what changes would be required to the overall process and why.
