The term \"atmospheric residue\" is used less frequently; it generally refers to the oil at the bottom of an atmospheric distillation column when no vacuum distillation section is employed. Residue refers to those heavy fraction oils in the refining process that are not further processed within this unit and are sent out of the facility. In processes equipped with vacuum distillation, the crude oil at the bottom of the atmospheric tower is sent to the vacuum tower for vacuum distillation. Atmospheric residue is generally used as a feedstock for catalytic cracking.
