The present invention relates to a process for upgrading a liquid petroleum or chemical stream wherein said stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. At least a fraction of up flowing vapor product is condensed to produce a condensate comprised of the heavier fraction of the vapor phase product stream and a lighter remaining vapor stream. The condensate and potentially the lighter remaining vapor stream are further hydroprocessed.
Countercurrent Hydroprocessing With Treatment Of Feedstream To Remove Particulates And Foulant Precursors
A process for upgrading a liquid petroleum or chemical stream wherein said feedstream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. The feedstream is treated so that it is substantially free of particulate matter and foulant precursors.

A process for upgrading a liquid petroleum or chemical stream wherein said stream flows countercurrent to the flow of a treat gas, such as a hydrogen-containing gas, in at least one reaction zone. The temperature of at least a portion of the liquid stream in the reactor is used to control the flooding characteristics of the reactor.

Abstract:
A process for hydroprocessing liquid petroleum and chemical streams in two or more hydroprocessing stages wherein the liquid and vapor products from the first stage are sent to a separation zone wherein a liquid phase fraction is separated from a vapor phse fraction which contains vaporized heary hydrocarbon components. The vapor phase fraction is passed to a sorption zone wherein at least a portion of the heavy hydrocarbon components is removed. Both the liquid phase fraction and the sorbed heavy hydrocarbon components are sent to at least one additional hydroprocessing stage.
