Entrance gate of crude oil in refineries is crude oil distillation unit, that aims to separate crude into process streams under atmospheric crude oil distillation unit . Bottom stream still contains some recoverable products. This can be converted into high added value derivative. To avoid thermal cracking vacuum distillation column is used. High value of metal content and residual carbon concentration in feedstock leads to quickly deactivation of catalyst used and raise the operational cost. To avoid this add a withdraw line of stream in treatment of heavy or light gasoil. Which removes the metal content? And to improve the yield of highly added derivative of crude oil vacuum distillation normally directed to asphalt production or in refineries with high conversion capacity to bottom barrel conversion unit like delayed cocking and solvent desulphating , it gives high added value derivative.

Atmospheric crude distillation unit , vacuum distillation unit , carbon concentration , deactivation of catalyst , desulphating , high added value derivative.
