A mixture containing 42 wt% benzene (B) and 58 wt% toluene (T) is fed to a distillation column at a flow rate of 100 kg per minute. The product vapor exiting the top of the column (the top product) contains 90% wt% benzene and 85% of the total benzene fed to the column outlets in this top product stream. Calculate the mass flow rate and mass composition of the product sequence leaving the bottom of the column. Calculate the volumetric flow rate of the top product, assuming it exits the distillation column as a stream of steam at 82C and 1 atm (abdominal). Physical property data (S.G. = specific gravity) from Table B-1: benzene S.G. = 0.879 MW = 78.11 g / mol toluene S.G. = 0.866 MW = 92.13 g / mol Water Density = 1.00 kg / L MW = 18.02 g / mol R = 0.08206 L atm / mol K

Question
A mixture containing 42 wt% benzene (B) and 58 wt% toluene (T) is fed to a distillation column at a flow rate of 100 kg per minute. The product vapor exiting the top of the column (the top product) contains 90% wt% benzene and 85% of the total benzene fed to the column outlets in this top product stream. Calculate the mass flow rate and mass composition of the product sequence leaving the bottom of the column. Calculate the volumetric flow rate of the top product, assuming it exits the distillation column as a stream of steam at 82C and 1 atm (abdominal). Physical property data (S.G. = specific gravity) from Table B-1: benzene S.G. = 0.879 MW = 78.11 g / mol toluene S.G. = 0.866 MW = 92.13 g / mol Water Density = 1.00 kg / L MW = 18.02 g / mol R = 0.08206 L atm / mol K
