METHOD OF AND APPARATUS FOR UPGRADING AND GASIFYING HEAVY HYDROCARBON FEEDS

摘要

An apparatus for producing sweet synthetic crude from a heavy hydrocarbon fe ed comprising: an upgrader (14) for receiving said heavy hydrocarbon feed and producing a distillate fraction including sour products, and high-carbon content by-products; a gasifier (32) for receiving the high-carbon content b y- products and producing synthetic fuel gas and sour by-products; a hydroprocessing unit (22) for receiving the sour by-products and hydrogen ga s, thereby producing gas and sweet crude; and a hydrogen recovery unit (42) for receiving said synthetic fuel gas and producing further hydrogen gas and hydrogen-depleted synthetic fuel gas, said further hydrogen gas being suppli ed to said hydroprocessing unit (22).
