QUESTION 2 10 points CH3OH. Methanol is produced by the reaction of CO with H2: C0+2H2...
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...

4.66. Methanol is formed from carbon monoxide and hydrogen in the gas-phase reaction CO 2H2 CH3OH (A) (B) (C) The mole fractions of the reactive species at equilibrium satisfy the relation 1 = Ke(T where P is the total pressure (atm), Ke the reaction equilibrium constant (atm2), and T the temperature (K). The equilibrium constant Ke equals 10.5 at 373 K, and 2.316 x 10-4 at 573 K. A semilog plot of Ke (logarithmic scale) versus 1/T (rectangular scale) is...
Methanol is synthesized from carbon monoxide and hydrogen (H2) in a catalytic reactor. CO + 2H2 → CH3OH The fresh feed to the process contains 32.0% mol of CO, 64% of H2 and 4% N2. This stream is mixed with a recirculation stream at a ratio of 5 mol recirculation / 1 mol fresh feed to the process. The mixture of these streams forms the feed stream to the reactor, which contains 13.0 mol% of N2. Low conversion is achieved...

In methanol production. CO + 2 H2 → CH3OH Fresh feed gas containing 65.5 % H2, 32.0 % CO and 2.5 % inserts A is used. The product gas is cooled that completely separates the methanol and the unreacted gas including inert is recycled. A purge stream was provided to remove the inserts. The gas entering the converter (Fresh feed and Recycle) contains 24.0 % CO, while the gas leaving the cooler/separator contains 20.0 % CO. What is the efficiency...

4.75. A catalytic reactor is used to produce formaldehyde from methanol in the reaction HCHO+ H2 CH-OН A single-pass conversion of 60.0% is achieved in the reactor. The methanol in the reactor product is separated from the formaldehyde and hydrogen in a multiple-unit process. The production rate of formaldehyde is 900.0 kg/h. (a) Calculate the required feed rate of methanol to the process (kmol/h) if there is no recycle. (b) Suppose the unreacted methanol is recovered and recycled to the...
