Why diesel fuel and industrial fuel oil are removed nearer the bottom of a distillation tower?

Diesel fuel and industrial fuel oil are removed nearer the bottom of a distillation tower because they have higher boiling points compared to lighter fractions like gasoline. In the distillation process, components are separated based on their boiling points, with heavier, less volatile substances condensing and collecting lower in the tower. This allows for efficient separation and collection of fuels based on their specific properties, optimizing the production of various petroleum products.
