A reflux column can be installed in the Augmentation tab in a fractionating still’s GUI. It is a specialization that cannot be installed together with other specialization augments.
A fractionating still with a reflux column installed produces an additional 50 mB of the produced fluid per operation. However, the machine can only process fossil fuels (liquifacted coal, crude oil and naphtha), and the amount of energy required per operation is increased by 100%.
