Batch distillation - Wikipedia

The simplest and most frequently used batch distillation configuration is the batch rectifier, including the alembic and pot still.The batch rectifier consists of a pot (or reboiler), rectifying column, a condenser, some means of splitting off a portion of the condensed vapour (distillate) as reflux, and one or more receivers.. The pot is filled with liquid mixture and heated.
