AROMATIC-ENRICHED DISTILLATE OIL PROCESSING METHOD AND SYSTEM

WIPO Patent Application WO/2021/083302

A1

An aromatic-enriched distillate oil processing method and system, comprising: introducing aromatic-enriched distillate oil (20) into a third reaction unit (21) to undergo hydrogenation saturation and then fractionation to obtain a first light component and a first heavy component (22); introducing deoiled asphalt (4) and an aromatic hydrocarbon-containing material flow to a hydrogen dissolution unit (23) to mix with hydrogen, and introducing the mixed material to a first reaction unit (7) to undergo a hydrogenation reaction, the first reaction unit (7) being a liquid-phase hydrogenation reaction unit; performing fractionation on a liquid-phase product from the first reaction unit (7) to obtain a second light component (8) and a second heavy component (9); introducing the second light component (8) to a second reaction unit (10) to undergo a reaction; and introducing the second heavy component (9) to a delayed coking unit (11) to undergo a reaction; or taking the second heavy component (9) as a low-sulfur marine fuel oil component. The processing process can implement high-value utilization of DOA.
