The optimal recoveries of component 1 and 2 in the main-cuts, off-cut composition, amount of each cut, duration of each task and reflux ratio profiles for each task are given in Table 6.7. They show that the desired product purities can be achieved to yield a maximum productivity for the operation of 2.0 per hr. The accumulated and instant distillate composition profiles for the optimal operation are
