ANDRITZ reactor internals

Engineered for reliability

ANDRITZ Euroslot and ANDRITZ Fiedler, both members of the ANDRITZ GROUP, together provide a unique breadth and depth of expertise across a range of industry sectors – from oil and gas, to petrochemicals and refineries, water treatment, filtration, food processing, and the paper industry.

Clients value the company’s extensive service in the fields of design, manufacture, and site installation of reactor and column internals.

Hydroprocessing reactors in the refining and petrochemical industries require very specific designs to achieve good performance over the years and minimize maintenance turnaround.

ANDRITZ delivers production units for reactor internals to achieve optimum and trouble free operations, considering the following parameters as key elements:

Uniform distribution
Severe pressure and design pressure compliance
Thermal stability of components
Maximizing of catalyst volume and duration of operating cycles
Low fouling system reducing potential pressure drop build-up

Feed diffuser and vortex breaker

Liquid distributor trays

Support grids

Quench injections, collection trays, and mixing chambers

The mixing system comprises a horizontal collection tray, a mixing chamber positioned below the collection tray, and at least one passageway extending through the collection tray into the mixing chamber. This mixing chamber and the collection tray define a two-phase mixing volume. The passageway conducts fluid from above the collection tray into the mixing chamber, which preferably includes at least one outlet opening for the downward passage of fluid.
In particular, mixing of quench fluid is significantly improved when quench is introduced into a region above the collection tray and where a preferred direction of quench injection is selected to cause a rotational flow on the collection tray.
