Why do you supply stripping steam in a distillation column when you are heating the crude to a temperature where fractions lighter than residuum go up?
Stripping steam aids in separation in the column by "stripping' lighter components to higher trays in the column. While the crude is heated to a temperature where the pure components would normally go up, in crude oil the lighter components are often entrained in the heavier ones and the separation is not ideal. In actual practice stripping steam rates affect the flash points of the products as well as the concentration of hydrogen sulfide (H2S) in the products. The stripping steam added to the bottom of the column also affects the amount of overflash in the flash zone.

What are petroleum distillates?
Petroleum distillates are products made from crude oil. The process of taking crude oil and creating finished products is called distillation. The first step of the refining process is running crude oil through a distillation tower. At this time crude oil is separated into different basic products which then undergo further process at the refinery to create products that are sold to consumers. There are three classes of distillate products: Light: Liquid Petroleum Gas(LPG), gasoline, and naptha. Medium: Kerosene (and jet fuel) and diesel. Heavy/Residuum: Heavy fuel/bunker fuel, wax, and asphalt.
