5.19 A stripper operating at 50 psia with three equilibrium stages is used to strip 1,000 kmol/h of liquid at 300°F having the follow- ing molar composition: 0.03% C₁, 0.22% C₂, 1.82% C3, 4.47% nC4, 8.59% nC5, 84.87% nC10. The stripping agent is 1,000 kmol/h of superheated steam at 300°F and 50 psia. Use the Kremser equa- tion to estimate the compositions and flow rates of the stripped liq- uid and exiting rich gas. Assume a K-value for C10 of 0.20 and assume that no steam is absorbed. However, calculate the dew-point temperature of the exiting rich gas at 50 psia. If that temperature is above 300°F, what would you suggest be done?

5.19 A stripper operating at 50 psia with three equilibrium stages
is used to strip 1,000 kmol/h of liquid at 300°F having the follow-
ing molar composition: 0.03% C₁, 0.22% C₂, 1.82% C3, 4.47%
nC4, 8.59% nC5, 84.87% nC10. The stripping agent is 1,000 kmol/h
of superheated steam at 300°F and 50 psia. Use the Kremser equa-
tion to estimate the compositions and flow rates of the stripped liq-
uid and exiting rich gas.
Assume a K-value for C10 of 0.20 and assume that no steam is
absorbed. However, calculate the dew-point temperature of the
exiting rich gas at 50 psia. If that temperature is above 300°F, what
would you suggest be done?
