(a) A feed stream of 100 kg/hr enters a separation column at 65C and 10 bar. The feed has a composition of 33 wt% component A, 38.5 wt% component B and the remainder is component C. Inside the separation column the pressure is reduced causing the feed stream to separate into two streams, a vapor and liquid stream. 80% of the feed of component B is removed in the vapor stream and component A accounts for 18 wt% of the vapor stream. The mass fraction of component B in the liquid stream is 22 wt%. (i) (iii) (iv) Assume: there is no accumulation of material within the separation column; no chemical reactions occur in the separation column. Is the process batch or continuous? Draw a block flow diagram of the process and label all known streams. Calculate the mass flow rate of component B in the vapor and liquid streams. Using the known stream values, calculate the complete composition of the feed, vapor and liquid streams. (a) A feed stream of 100 kg/hr enters a separation column at 65C and 10 bar.
