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...

. (5pt) Ethylene oxide is produced by the catalytic oxidation of cthylenc C3H4 + O2 → C2H40 An undesired competing reaction is the combustion of ethylene CO2 + H2O C2H4 + O2 The feed to the reactor contains 4 moles of ethylene per mole of oxygen, while the oxygen contains 0.4% inerts. The single pass conversion of ethylene is 15% and for every 100 moles of ethylene consumed in the reactor, 80 moles of ethylene oxide emerges in the reactor...

Terephthalic acid (TPA) is synthesized from -xylene (PX) in the
process C8H10 +302 – C8H6O4 +2H2O shown below. A fresh feed of pure
liquid PX combines with a recycle stream containing PX and a
solution (S) of a catalyst (a cobalt salt) in a solvent (methanol).
The combined stream, which contains S and PX in a 3:1 mass ratio,
is fed to a reactor in which 90% of the PX is converted to TPA. A
stream of air at 25...

As a first step in the production of nitric acid, ammonia is oxidized to form nitric oxide: 4NH3 + 5O2→4NO + 6H2O A side reaction also occurs: 2NH3 +3/2O2→N2 +3H2O A reactor is designed to carry out this reaction isothermally at 600°C, with pure oxygen fed to the reactor in 50% excess. At these conditions, all components are in the gas phase. The conversion of ammonia is 80%, and the selectivity ratio of NO to N2 in the product stream...

Sunflower oil contains 0.080 mol palmitic acid 0.060 mol stearic acid 020 mol oleic acid (craH30o2ymol, and 0.66 mol linoleic acid (cBHzozymol. To create margarine from form solid oil, the liquid oleic and linoleic acids are hydrogenated in the presence of a metal catalyst to stearic Heo, amargarine a stream 355.0 mol sunnower is fed into a reactor. The fresh hydrogen source available is a mixture 0.96 mol o.040 (N2 is this ess.) To insure complete hydrogenation, the hydrogen gas...

Your company assigns you to a new project with the goal of designing a continuous stirred tank reactor (CSTR) to produce 100 million kglyr of ethylene glycol (EG) from ethylene oxide (EO) and water (W) using H2SO4 as the catalyst. The reaction is: EO W EG H2 но Two streams will be mixed and reacted in the CSTR: flow of 20 gmol/L of EO in Vw An equal volumetric flow rate of a solution of 9.0 g/L of H2SO4 in...

Methanol is produced by reacting CO and H2. A fresh feed stream containing CO and H2joins a recycle stream, and the combined stream is fed to a reactor. A portion of the methanol leaving the reactor is condensed, and the unconsumed CO and H2and uncondensed methanol are recycled. The stream going from the reactor to the condenser flows at a rate of 275 mol/min and contains 63.1 mole% H2, 27.4 mole% CO and 9.53 mole% CH3OH. The mole fraction of...
