Batch distillation at constant reflux
For batch distillation under constant reflux ratio, r is kept constant and distillation is continued until the distillate composition xd dropped below a certain pre-specified level from the operating line equation, note that if r is constant and xd is decreasing, then its slope remained constant while its intercept decreases. 46 composition of distillate and bottoms at constant reflux by aspen batch distillation software 22 47 distillate and bottoms holdup at constant reflux. Occurs in chemical processes (for example, when changing the reflux ratio during a distillation operation) as with any other chemical process, the modelling of batch distillation requires the accurate consideration of physical properties in order to model the thermodynamics of the process in an accurate manner. Optimal operation of batch reactive distillation process piecewise constant reflux ratio level is optimised over the batch time of operation 51 specifications.
This method, described in figure 47a and b, uses a batch distillation operation that incorporates more than 100 theoretical plates and a high reflux ratio (r/p) of 100, as described in figure 47a. Column for batch distillation in the still after the first distillation may be added to the next batch maintain constant reflux in batch distillation.
