# Errata

CHAPTER 3

p. 111, table 3-15
• Under Reactor - volume, m should be volume, m3.

CHAPTER 4

p. 194, problem 4-14
• Replace first four words with "For a second."
• The sentence beginning, "100 percent separation of all ethylbenzene…" should read, "100 percent separation and recycle of all ethylbenzene from the reactor exit stream."
• The stated catalyst life of 1100 h is actually the period between regenerations. Assume the catalyst life is 1 year.
• Due to lack of thermodynamic data for several components, heat integration should not be attempted.
p. 195, problem 4-18
• There should be 2 g of metal catalyst per unit, not 0.5 kg.

CHAPTER 6

p. 258, Method G: Turnover Ratio section
• Last line should read, "the ratio can be approximated as 1.‡" (rather than 0.5).
p. 275, problem 6-1
• The 100 m2 in the first sentence should be 10 m2.

CHAPTER 9

p. 405, equation 9-80
• The coefficient 7.61x10-5 must be replaced by (0.0145)(0.0254)n.
p. 406, table 9-4
• There are corrections in first two columns in table 9-4, indicated by the underlines. The first two columns should read as follows:
 By Eq. (9-81) By Eq. (9-76) 0.22 0.25 0.12 0.14 0.07 0.088 0.037 0.049
p. 435, problem 9-3
• The first coefficient of the total variable operating costs should be 1.22X10-3 (i.e. 0.00122), not 9.78X105.

CHAPTER 12

p. 554, table 12-10
for spherical shells (3rd equation on left from the top)
• Add a 2 before SEj in the denominator.

CHAPTER 13

p. 639, problem 13-8
• Add that the ethanol yield is 0.47 kg ethanol/kg of glucose consumed. The correct unit for the rate coefficient, k, is 1/s, not kg/m3.s.
p. 639, problem 13-10
• The heat of reaction is 89.98 MJ/kg mol CH3OH, not kJ/kg mol.
• The symbol pi represents fugacity, in kPa, of component i, which equals the partial pressure, pi = Pyi, in kPa, when the fugacity coefficient is 1.
p. 640, problem 13-12
• The third sentence should read, "In the proposed recovery process, each kg of catalyst-containing ceramic is mixed with two kg of aqueous sodium cyanide solution, and the Pt is dissolved by complexing with the cyanide."

CHAPTER 14

p. 657, equation 14-18
• Coefficient should be 0.023, not 0.23.
p. 751, problem 14-11
• Equation should read μL  =  μW  = 4 × 10-4Pa•s   NOT 4 × 10-6Pa• s
p. 752, problem 14-14
• 30°C should be 20°C
• 21°C should be 20°C
• 0.0082 should be 0.082
p. 752, problem 14-15
• 2944 kPa should be 1944 kPa

CHAPTER 15

p. 784, figure 15-7
• Ordinates should be 10-1, 10-2, 10-3, not 1, 10-1, 10-2 respectively
p. 867, figure 15-46
p. 822, bottom line equation
• Should read nF, not nP.
p. 874, problem15-5

APPENDIX A

p. 880, table A-1
• The quantity of Pa should read "Pressure or stress," not "Pressure of stress."

APPENDIX C

p. 943, problem 24
• In first paragraph, should read 5 × 10 -11m2 / s  NOT 5 × 10-9m / s.

REFERENCE INDEX

p. 978
• Reference should read Treybal, not Treyal.
