Integrated ebullated-bed hydroprocessing, fixed bed hydroprocessing and coking process for whole crude oil conversion into hydrotreated distillates and petroleum green coke

摘要

A system and process for upgrading a whole crude oil feed in an integrated ebullated-bed and hydrotreater is provided in which the whole crude oil is flashed into a flashed straight run distillates fraction and an atmospheric residue fraction. The atmospheric residue fraction is hydroprocessed in an ebullated-bed reaction zone, while the flashed straight run distillates fraction and the products fraction produced from the ebullated-bed reaction zone are hydrotreated in a fixed-bed reaction zone. The unconverted residue fraction from the ebullated-bed reaction zone is processed in a coker unit to produce high quality petroleum green coke.
