INTEGRATED PROCESS AND SYSTEM TO UPGRADE CRUDE OIL

摘要

The processes and systems herein integrate hydroprocessing and coking in a manner to effectively upgrade / desulfurize crude oil feedstocks. An initial liquid hydrocarbon feedstock, such as crude oil, is upgraded by fractionating both the hydrocarbon feedstock and coker thermally cracked hydrocarbon products in a fractionating zone. A coker recycle stream is thermally cracked to produce coker thermally cracked hydrocarbon products that are passed to the fractionating zone. The hydrocarbon distillates are hydroprocessed under conditions effective for desulfurization and conversion into lighter hydrocarbon distillates to produce a hydroprocessed liquid hydrocarbon effluent, such as a bottomless synthetic crude oil.
