Abstract
A hot stripped hydroprocessed stream from a stripper column may be sent directly to a vacuum fractionation column instead of being first processed in an atmospheric fractionation column. If a separate warm stripper column is used, both the warm stripped stream and a hot stripped stream may be fractionated in the same fractionation column, particularly a vacuum fractionation column.
Claims13
An apparatus for hydroprocessing comprising:
- a hydroprocessing reactor;
- a hot separator in communication with said hydroprocessing reactor;
- a hot stripper column in communication with said hot separator and said hydroprocessing reactor;
- a warm separator in communication with said hydroprocessing reactor;
- a warm stripper column in communication with said warm separator and said hydroprocessing reactor and a warm stripped line is in communication with said warm stripper column;
- a cold stripper column in communication with said hydroprocessing reactor;
- a debutanizer column in communication with a net cold overhead line from said cold stripper;
- and
- a vacuum product fractionation column in direct communication with said hot stripper column via a hot stripped line.
