HYDROPROCESSING REACTOR INTERNALS HAVING REDUCED HEIGHT

摘要

The hydroprocessing reactor internals (HRI) have reduced height compared to standard HRI designs. In this design, HRI height reduction is achieved by placing a mixing chamber above the collection tray. A ring quench distributor is located around the fluid collection tray between the mixing chamber and reactor shell to eliminate the vertical space occupied by the distributor. The hydroprocessing reactor quench zone internals comprise a collection tray, a mixing chamber, a ring distributer, a rough liquid distribution tray, and a vapor-liquid distribution tray. Fluid mixing occurs in the mixing chamber and above the rough liquid distribution tray.
