Using Programmable Logic Controllers to Sequence a Batch Distillation Column
Quick fact
In automated batch distillation, a PLC can manage the entire cycle—from charging the feed and heating to reflux, through multiple product cuts, to shutdown—without human intervention, executing a sequence of hundreds of steps with millisecond precision.
Why this is interesting
You’ve seen a batch distillation column—but how does it know when to switch from heating up to collecting product, and when to shut down before something goes wrong? The answer is a programmable logic controller, a silent choreographer that runs the entire show.
