Abstract:
An improved nozzle device for a down-flow hydroprocessing reactor is disclosed. The down-flow nozzle is useful in the petroleum and chemical processing industries in catalytic reactions of hydrocarbon feedstocks in the presence of hydrogen, at an elevated temperature and pressure, to provide for the mixing and distribution of gas and liquid to reactor catalyst beds. Typical hydroprocessing applications include hydrotreating, hydrofinishing, hydrocracking and hydrodewaxing.

Claim (Index 1):
A nozzle for the distribution of a gas-liquid fluid mixture in a down-flow reactor comprising\n a nozzle body having a top, a bottom, a length, a width or a diameter, and a wall having an interior and exterior surface, the nozzle body comprising a gas inlet zone body portion, a liquid inlet zone body portion, and an exit zone body portion, wherein the gas inlet zone body portion defines a gas inlet zone volume and has at least two offset gas inlets for the passage of gas therethrough into the gas inlet zone volume and the liquid inlet zone body portion defines a liquid inlet zone volume and has at least one liquid inlet for the passage of liquid therethrough into the liquid inlet zone volume, the gas and liquid inlet zone volumes being in fluid communication; a nozzle cap located at the top of the nozzle body enclosing the top of the gas inlet zone body portion; and a converging-diverging nozzle restrictor located in the exit zone at the bottom of the nozzle body, the nozzle restrictor having a frustoconical converging zone and a frustoconical diverging zone in fluid communication with the liquid inlet zone.
