3 Tutorial 4 - Question Q1 Solution a) Define the light key (LK) and heavy key (HK) components. F = 2000 kmol/h XMET = 0.18 XETH = 0.32 X = 0.26 Xa=0.24 ! RETH = 95% + F = 2000 kmol/h XMET= 0.18 XETH = 0.32 XP = 0.26 X8 = 0.24 B Rop=98% Assumptions: F = 2000 kmol/h XMET = 0.18 XETH = 0.32 XP = 0.26 X₂8 = 0.24 100% recovery of methanol in D 100% recovery of n-butanol in B Tutorial 4 - Question Q1 Solution The composition of D and B is controlled by the separation of ethanol and n-propanol. VolatiliyETH > Volatiliy Light key = ethanol Heavy key = n-propanol b) Determine the outgoing compositions for all the components.

Multicomponent Flash Distillation A mixture of methanol (1), ethanol (2), n-propanol (3) and n-butanol (4) is fed into a distillation column. The feed flow rate is 2000 kmol/h and its mole composition is given in the table below. The goal is to achieve 95% recovery of ethanol in the distillate and 98% recovery of n-propanol in the bottoms. a) Define the light key (LK) and heavy key (HK) components. b) Determine the outgoing compositions for all the components. Assumption: methanol and n-butanol are only present in the distillate and bottom streams, respectively Component z methanol (1) 0.18 ethanol (2) 0.32 n-propanol (3) 0.26 n-butanol (4) 0.24
