1. Ethanol is produced by the hydration of ethylene. Some of the ethanol product is converted in an undesired side reaction to diethyl ether and water. C2H4 (g) + H20 (1) → C2H5OH (1) 2 C2H5OH (1) → (C2H5)20 (1) + H20 (1) The feeds to the reactor are ethylene gas and liquid water, each @ 25°C, 1 atm. A sample of the reactor effluent is analyzed and found to be 15°C and contain 43.3 mol% ethylene (g), 2.5% ethanol...
Q4/ Toluene gas (CH3) enters a continuous adiabatic heat exchanger at (35°C) and (300 KPa) and exits at (260°C).

Ethylene oxide is produced by the catalytic oxidation of ethylene: C2H4 (g) + 1/2 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: C2H4 and O2 are recycled to the reactor, C2H4O is sold, and CO2 and...
