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 16):
A method for making a nozzle for the distribution of a gas-liquid fluid mixture in a down-flow reactor comprising\n providing a standard size pipe having a defined length and width or diameter to form a nozzle body having a top, a bottom, a length, a width or a diameter, and a wall having an interior and exterior surface; forming a gas inlet zone body portion in the nozzle body comprising forming at least two offset gas inlets through the wall of the gas inlet zone body portion; forming a liquid inlet zone body portion in the nozzle body comprising forming at least one liquid inlet through the wall of the liquid inlet zone body portion; forming an exit zone body portion in the nozzle comprising adapting or configuring the bottom of the nozzle body to include a nozzle restrictor; forming a nozzle cap configured to enclose the top of the gas inlet zone body portion as an integral part of the top of the nozzle body or from a separate material; forming a nozzle restrictor comprising a frustoconical converging zone and a frustoconical diverging zone as an integral part of the bottom of the nozzle body or from a separate material; affixing the nozzle cap to the top of the nozzle body to enclose the top of the gas inlet zone body portion when formed from the separate material; and inserting or attaching the nozzle restrictor when formed from the separate material.
