DEVICE AND METHOD FOR HYDROGENATION REFINING

Document Type and Number:

WIPO Patent Application WO/2000/042130

Kind Code:

A1

Abstract:

A device for hydrogenation-refining hydrocarbon stock oil containing sulfur-containing compounds, comprising a first catalyst layer (33), a second catalyst layer (38), an upper space (34) for separating gaseous components from liquid components, a lower space (36) and a valve tray (35) for partitioning the upper space (34) from the lower space (36). When hydrogen discharged from a hydrogen nozzle (40) disposed in the lower space is passed through liquid components collected on the valve tray, stripping is performed on the liquid components. Hydrogen discharged from the nozzle (40) is introduced into the second catalyst layer (38) in a parallel flow with the stripped liquid components. Hydrocarbon stock oil can contain less sulfur, less nitrogen and less aromatic components than ever by means of stripping. Because of its simple construction, the hydrogenation-refining device can be easily remodeled from an existing device.
