Improve the 5 Distillation Point for an Individual Cut

As the supply and demand of global crude changes, heavier crudes become more attractive to process. However, many existing columns cannot produce cuts that meet distillation product specifications. There are many process changes that could improve the distillation curve of a given product However, it may be unclear what the side effects of a given change could be. In this case study, we look at how we can improve the distillation curve (5%) of the heavy naphtha and kerosene cut One option is to draw more or less of a particular cut to force the distillation curve to shift However, this will affect other product draws as well.
