Abstract

A hydroprocessing process for removing impurities from a feed (30) comprising a hydrocarbonaceous liquid comprises at least one cocurrent, upflow hydroprocessing reaction stage (18), a vapor-liquid contacting stage (20) and a downflow hydroprocessing reaction stage (12). The feed and hydrogen react in the upflow stage (18) to produce a partially hydroprocessed liquid and vapor effluent. The vapor contacts a hydrocarbonaceous liquid in the contacting stage (20), which transfers impurities from the vapor into the liquid. The impurities-enriched contacting liquid mixes with the upflow stage liquid effluent and the combined liquid effluents react with hydrogen in the downflow reaction stage, to form a hydroprocessed product liquid and vapor effluent. Additional product liquid is recovered by cooling and condensing either or both the contacting and downflow stage vapor effluents.

Claims (19)

1. A staged hydroprocessing process comprising at least one cocurrent upflow hydroprocessing reaction stage, at least one vapor-liquid contacting stage and at least one downflow hydroprocessing reaction stage, for removing one or more impurities from a feed comprising a hydrocarbonaceous liquid, which process comprises the steps of:
(a) reacting said feed with hydrogen in a cocurrent, upflow hydroprocessing reaction stage, which comprises the first reaction stage, in the presence of a hydroprocessing catalyst at reaction conditions effective to form a first stage effluent having a lower impurity content than said feed, said effluent comprising a first stage hydroprocessed hydrocarbonaceous liquid and vapor, both of which still contain said impurities, said vapor containing hydroprocessed hydrocarbonaceous feed components, with said impurities in equilibrium between said liquid and vapor effluents;
(b) separating said first stage liquid and vapor effluents;
(c) contacting said vapor effluent, in a contacting stage, with a hydrocarbonaceous liquid, under conditions such that impurities in said vapor transfer to said liquid, to form a contacting stage effluent comprising a hydrocarbonaceous liquid of increased impurity content and a vapor comprising hydroprocessed hydrocarbonaceous feed components having an impurity content less than that of said first stage vapor effluent;
(d) combining said first and contacting stage liquid effluents and passing them into a downflow hydroprocessing reaction stage, and (e) reacting said combined liquid effluents with hydrogen in said downflow hydroprocessing reaction stage, in the presence of a hydroprocessing catalyst at reaction conditions effective to form a downflow reaction stage effluent comprising a hydroprocessed hydrocarbonaceous liquid and a vapor comprising hydroprocessed hydrocarbonaceous feed components, wherein said liquid and vapor feed components have an impurity content lower than said feed and respective upflow stage effluents.
2. A process according to claim 1 wherein said upflow and downflow reaction stage catalysts are the same or different.

11. A process according to claim 10 wherein said upflow and downflow reaction stage catalysts are the same or different.
12. A process according to claim 11 wherein said downflow reaction stage liquid effluent comprises product liquid.

A process according to claim 12 wherein said contacting conditions comprise at least one of (i) said contacting temperature being below that of said vapor, and (ii) said contacting liquid impurity content being below what it would be, if said liquid was in equilibrium concentration with said vapor, with respect to said impurity concentration.
14. A process according to claim 13 wherein said contacting stage vapor effluent is cooled to condense a portion of said hydrocarbon components to liquid.
15. A process according to claim 14 wherein said contacting liquid is cooled to a temperature below that of said vapor before said contacting.
16. A process according to claim 13 wherein said contacting stage includes internal reflux.
17. A process according to claim 13 wherein said downflow reaction stage vapor effluent is cooled to condense a portion of said hydrotreated hydrocarbon components to liquid.
