The products from the crude distillation unit (atmospheric and vacuum distillation) are then chosen. Typical products with their end points are shown in example E4.2.The volume percent of each cut is determined by calculating the cumulative volume percent for each fraction at its end boiling point from any of the fit procedures explained earlier in Section 3.3 and then calculating the difference.

Crude with high salt content will typically be processed through a desalter before going to distillation, to remove salts that could cause corrosion in the distillation tower. Inputs. The primary input to an atmospheric distillation unit is crude oil. This can be a single crude oil or a mixture of several different crude oil grades.
