Title:
単一反応槽における二段水素処理およびストリッピング
Document Type and Number:
Japanese Patent JP4206268
Kind Code:
B2
Abstract:
A hydrocarbonaceous feed is hydroprocessed in a single vessel containing two reaction stages and a stripping stage. The feed is fed into the first reaction stage to produce a vapor and liquid effluent which are separated, and the liquid stripped. The stripped liquid is passed as feed into the second stage, in which it meets with fresh hydrogen to produce a hydroprocessed liquid product and a hydrogen-rich vapor. The vapor is passed into the first stage, to provide the hydrogen for that stage. The use of a single vessel provides an efficient and economical addition to, or replacement for, a vessel for an existing hydroprocessing facility.
