Chapter 14, Problem 14.5P

The decomposition of cyclohexane to benzene and hydrogen is mass transfer–limited at high temperatures. The reaction is carried out in a 5-cm-ID pipe 20 m in length packed with cylindrical pellets 0.5 cm in diameter and 0.5 cm in length. The pellets are coated with the catalyst only on the outside. The bed porosity is 40%. The entering volumetric flow rate is 60 dm3/min.

Green engineering

  1. (a) Calculate the number of pipes necessary to achieve 99.9% conversion of cyclohexane from an entering gas stream of 5% cyclohexane and 95% H2 at 2 atm and 500°C.
  2. (b) Plot conversion as a function of pipe length.
  3. (c) How much would your answer change if the pellet diameter and length were each cut in half?
  4. (d) How would your answer to part (a) change if the feed were pure cyclohexane?
  5. (e) What do you believe is the point of this problem? Is the focus really green CRE? How so?

4. Show that the fraction, F, of the energy released from a supercritical chain reaction that originates in the final m generations of the chain is given approximately by F= 1 km provided the total number of generations is large.
PLEASE SOLVE STEP BY STEP WITHOUT ARTIFICIAL INTELLIGENCE OR CHATGPT I don't understand why you use chatgpt, if I wanted to I would do it myself, I need to learn from you, not from being a d amn robot. SOLVE BY HAND STEP BY STEP    A solution containing 7.5% sulfuric acid by weight at 70 °F is concentrated to 45% by weight by evaporating water. The concentrated solution and the water vapor exit the evaporator at 170 °F and 1 atm. Calculate the rate at which heat must be transferred to the evaporator to process 1500 lbm/hr of the feed solution to the evaporator. It is recommended to use the enthalpy-concentration diagram for sulfuric acid from Chapter 8 of Felder's book or an enthalpy-concentration diagram for sulfuric acid found in another unit operations book or chemical engineering manual such as Perry's.

SOLVE BY HAND STEP BY STEP   Suppose that the system designed in problem 33 of the Thermodynamics II problem set from UAM-Azcapotzalco is relocated to another area near the sea, specifically, Ciudad del Carmen, Campeche. Recalculate the compressor-cooler system for the new environmental conditions. Make the considerations you deem logical in redesigning your system. Indicate the references or sources where you obtained your data.
