A hydrocarbon stream composed of 40 mol% n-butane and 60 mol% n-octane is fed at 100 kmol/h to a flash vessel operating at 5 bar and 145°C. The liquid outlet stream of the flash vessel is then sent to a distillation column with a partial condenser to further separate the components. 90% of the butane in the feed to the column is recovered in the overhead vapor product (distillate), along with small amounts of octane. The bottoms product contains octane which accounts for 75% of the octane in the fresh hydrocarbon feed (to the flash vessel). The condenser and reboiler operating temperatures are 136.7°C and 165.7°C, respectively. Determine the compositions of the liquid outlet stream of the condenser and the vapor outlet stream of the reboiler.

Question
A hydrocarbon stream composed of 40 mol% n-butane and 60 mol% n-octane is fed at 100 kmol/h to a flash vessel operating at 5 bar and 145°C. The liquid outlet stream of the flash vessel is then sent to a distillation column with a partial condenser to further separate the components. 90% of the butane in the feed to the column is recovered in the overhead vapor product (distillate), along with small amounts of octane. The bottoms product contains octane which accounts for 75% of the octane in the fresh hydrocarbon feed (to the flash vessel). The condenser and reboiler operating temperatures are 136.7°C and 165.7°C, respectively. Determine the compositions of the liquid outlet stream of the condenser and the vapor outlet stream of the reboiler.
