  • Compact quench zone reactor internals
    Patent number: 11298670
    Abstract: Hydroprocessing reactor internals height reduction is achieved by placing a mixing chamber above the collection tray. The mixing chamber has spillways on the top (top spillways) and the side of the mixing chamber (side spillways) for fluid entry. The design of the spillways has a significant impact on pressure drop. The pressure drop is reduced by having wide shallow spillways rather than narrow and deep spillways without impacting mixing performance. With both side and top spillways, the height of the mixing chamber can be reduced significantly with minimal impact on fluid mixing and pressure drop.
