In a distillation tower, larger hydrocarbons, which have higher boiling points, tend to collect at the bottom of the tower. As the mixture is heated, lighter hydrocarbons vaporize and rise through the column, while the heavier ones condense and fall back down. The separation occurs due to differences in boiling points, allowing for the collection of various hydrocarbon fractions at different levels. Thus, the heavier fractions are typically drawn off from the lower sections of the tower.
