Integrated processes and apparatuses for upgrading a hydrocarbon feedstock

An integrated process for upgrading a hydrocarbon feedstream comprising:

• passing the hydrocarbon feedstream to a first hydroprocessing reactor in a reaction vessel, the first hydroprocessing reactor containing at least one bed of a first hydroprocessing catalyst, wherein the hydrocarbon feedstream is contacted with the first hydroprocessing catalyst under first hydroprocessing conditions in the presence of hydrogen to produce a first hydroprocessed effluent stream;
• separating the first hydroprocessed effluent stream in a hot separator to produce a vapor stream and a liquid hydrocarbon stream;
• passing at least a portion of the liquid hydrocarbon stream to a fractionation column to provide a plurality of fractionator product streams;
• passing a fractionator product stream from the plurality of fractionator product streams to a second hydroprocessing reactor, the second hydroprocessing reactor containing at least one bed of a second hydroprocessing catalyst, wherein the fractionator product stream is contacted with the second hydroprocessing catalyst under second hydroprocessing conditions in the presence of hydrogen to produce a second hydroprocessed effluent stream comprising a second vapor phase and a liquid product;
• and
• passing at least a portion of the second vapor phase from the second hydroprocessing reactor to the first hydroprocessing reactor through a tray having a vapor opening present in a one or more chimneys present on the tray, wherein the vapor opening is spaced apart from the tray, and preventing vapor present in the first hydroprocessing reactor from passing to the second hydroprocessing reactor.

An integrated apparatus for upgrading a hydrocarbon feedstream comprising:

• a first hydroprocessing reactor in a reaction vessel, the first hydroprocessing reactor containing at least one bed of a first hydroprocessing catalyst;
• a hot separator in communication with the first hydroprocessing reactor providing a vapor stream in a hot separator overhead line and a liquid hydrocarbon stream in a hot separator bottoms line;
• a second hydroprocessing reactor in communication with the hot separator and disposed in the reaction vessel above the first hydroprocessing reactor, the second hydroprocessing reactor containing at least one bed of a second hydroprocessing catalyst and providing a second hydroprocessing effluent stream;
• a tray located between the first hydroprocessing reactor and the second hydroprocessing reactor, the tray having a vapor opening present in the one more chimneys present on the tray, wherein vapor opening is spaced apart from the bottom of the one or more weirs located on the tray;
• and
• a liquid product line in communication with the tray withdrawing a liquid product stream from the second hydroprocessing effluent stream and the liquid product line is in communication with the hot separator overhead line to provide a combined line.
