METHOD AND SYSTEM FOR PRODUCING FUEL FROM A HEAVY HYDROCARBON FEEDSTOCK

摘要

A method of providing fuel suitable for the generation of electrical power, which comprises: (i) subjecting a heavy hydrocarbon feedstock to delayed coking to yield coke and liquid hydrocarbon output; (ii) gasifying coke, produced in step (i), to yield synthesis gas; (iii) removing hydrogen sulfide from synthesis gas produced in step (ii); (iv) recovering hydrogen from synthesis gas subjected to the hydrogen-sulfide-removal of step (iii); (v) hydrotreating liquid hydrocarbon output produced in step (i), a substantial amount of the hydrogen used in said hydrotreatment being hydrogen recovered in step (iv); and (vi) transporting liquid hydrocarbon output subjected to step (v), and synthesis gas subjected to step (iii) and/or both steps (iii) and (iv), for use as fuel in a combustion turbine adapted for the generation of electrical power; and further a method of generating electrical power, and systems for producing said fuel and generating electrical power.
