Question: A stripper operating at 50 psia with three equilibrium stages is used to strip 1,000 kmol/h of liquid at 300F having the following molar composition:

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 following 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 equation to estimate the compositions and flow rates of the stripped liquid 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?
