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...

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...

Assume that in an NH3 plant that has just employed you as a Chemical Engineer or Metallurgical Engineer, two compounds used in the production of NH3 are contained in a fresh feed stream that is fed into the process plant in the same proportion as it appears in Equation (1). The fresh feed stream also contains 0.2 volume % Ar. It is given that the single pass conversion of N2 to NH3 is twenty-five percent, and that a portion of...

Problem #1: Haber-Bosch process. The Haber-Bosch process is an equilibrium-limited catalyzed reaction that converts nitrogen (N2) and hydrogen (H2) into ammonia (NH3). The process won Haber a Nobel Prize since it provided a way to produce fertilizer for millions of people at the beginning of the 20th century. However, this process typically has very low single pass conversion due to a low equilibrium at the prevailing temperature and therefore a recycle stream is required to achieve a high overall conversion....

1. Acrylonitrile is produced by the reaction of propylene, ammonia, and oxygen C3H6 + NH3 + O2 C3H3N + 3H2O The feed contains 10 mole% propylene, 12% ammonia, and 78% air. A fractional conversion of 30% of the limiting reactant is achieved. Determine which reactant is limiting, the percentage by which each of the other reactants is in excess, and the molar flow rates of all product gas constituents for a 30% conversion of the limiting reactant, taking 100...
