ChE 101 Lab Exercise 4 05 December 2012 Materials Balance (Non-reacting Systems) THR/WRU 1. A 40-mol-% aqueous ethanol solution is to be distilled into two streams: a distillate with 98% ethanol and a side stream with 60%. 98% of the alcohol in the feed is to be recovered in these two products; only 2% goes into the bottoms. If the bottoms product contains 2% ethanol‚ calculate the amount of the different streams per 1000 kmol of feed stream. Given: Recovery = 98% of ethanol in
