Description
Atmospheric Bottoms is the heaviest of the Distillation cuts out of the Atmospheric Distillation Tower. It consists of all of the components of Crude Oil that have boiling points above about 650 °F (343 °C). These cuts cannot be vaporized in the Atmospheric Distillation Tower because they begin to crack or break down at the temperatures required to achieve vaporization. Consequently, they remain in liquid form during the Atmospheric Distillation process and literally come out of the "bottom" of the tower.
