Ethylene oxide (C2H4O) is produced by the catalytic oxidation of ethylene (C2H4). That is ethylene is reacted with O2. An undesired side reaction is the combustion of ethylene to CO2 and H2O. The fresh feed to the process consists of oxygen and ethylene. The fresh feed is mixed with a recycle stream, also containing oxygen and ethylene, and fed to the reactor. The feed to the reactor contains a 3:1 molar ratio of ethylene to oxygen. The single pass conversion of ethylene is 20%, and for every 100 moles ethylene consumed in the reactor, 90 moles of ethylene oxide emerge in the reactor products. A multi-unit process is used to separate the products; ethylene and oxygen are recycled to be mixed with the fresh feed; ethylene oxide is sold as a product; and carbon dioxide and water are discarded. Assume a basis of 100 mole of feed to the reactor (not fresh feed to the process).

(a) Determine the moles of fresh feed required and composition of the fresh feed. (b) Determine the moles of ethylene oxide produced and the overall conversion of

ethylene in the process.

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...

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...

Consider the pair of reactions in which ethylene (C2H4) is oxidized either to ethylene oxide (C2H4O, desired) or to carbon dioxide (undesired). (hint: assume 100 moles feed entering in reactor) C2H4 + ½ O2 → C2H4O C2H4 + 3 O2 → 2 CO2 + 2 H2O The feed to the reactor contains 25% mole ethylene and 75% mole oxygen. The conversion of ethylene is 75% and the selectivity of ethylene oxide over carbon dioxide is 12. a) determine...

1. Formaldehyde can be produced by oxidation of C2H4 and the following reaction may occur. C2H4 + ½ O2  C2H4O C2H4 + 3O2  2CO2 + 2H2O Using molecular balance method. Equimolar quantity of C2H4 and O2 was used and the product gas analysis shows 28.57% C2H4O, 11.43% CO2, 11.43% H2O, 22.86% C2H4 and 25.71 % O2. Calculate the % conversion of C2H4 and % Yield of C2H4O.

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...

Ethanol can be produced commercially by the hydration of ethylene: C2H4 + H2O -> C2H5OH Some of the product is converted to diethyl ether in the side reaction: 2C2H5OH -> (C2H5)2O + H2O The feed to the reactor contains ethylene, steam, and an inert gas. A sample of the reactor effluent gas is analyzed and found to contain 43.3 mol% ethylene, 2.5 mol% ethanol, 0.14 mol% ether, 9.3 mol% inerts, and the balance water. a. Take as a basis 100...
