Ethylene oxide is produced by the catalytic oxidation of ethylene:

C2H4(g)+12 O2(g)→C2H4O(g)

An undesired competing reaction is the combustion of ethylene to CO₂.

The feed to a reactor contains 2 mol C₂H₄/mol O₂. The conversion and yield in the reactor are respectively 25% and 0.70 mol C₂H₄O produced/mol C₂H₄ consumed. A multiple-unit process separates the reactor outlet stream components: C₂H₄and O₂ are recycled to the reactor, C₂H₄O is sold, and CO₂ and H₂O are discarded. The reactor inlet and outlet streams are each at 450°C, and the fresh feed and all species leaving the separation process are at 25°C. The combined fresh feed-recycle stream is preheated to 450°C.

(a)

Taking a basis of 2 mol of ethylene entering the reactor, draw and label a flowchart of the complete process (show the separation process as a single unit) and calculate the molar amounts and compositions of all process streams.

Ethylene oxide (C2H4O) is made by the catalytic reaction between ethylene (C2H4) and oxygen.Fresh ethylene, pure oxygen, and recycled ethylene are mixed to give a reactor feed gas containing 55%C2H4 which enters the reactor at 1 atm absolute and 300 oC. From test experiments, the single-pass conversion of ethylene in the reactor is 54% and, of this, 72% goes to ethylene oxide and the balance decomposes to CO2 and H2O. Most of the unreacted ethylene is separated from the reactor...

Ethanol (EtOH) can be produced by the hydration of ethylene, C2H4 + H2O ? C2H5OH, at 300?C and high pressure with a phosphoric acid catalyst. Downstream of the reactor, a condenser is used to separate the product, which contains only EtOH and H2O, from a recycle stream that mixes with the fresh feed before entering the reactor. The fresh feed contains 30 mol% C2H4 and the remainder is steam. The single pass conversion is 20%. a. Draw and label the...
