Product Description
Reactors used in the chemical, petrochemical and refining industries have different flow directions. This flow may be radial (Radial Flow) or vertical, downwards (Down Flow). HUILONG has specific experience over a long period in the construction of Radial Flow reactor internals for catalytic reforming units, isomerization and synthesis of ammonia and in the construction of Down Flow reactor internals for hydrotreating, hydrocracking, urea and methanol synthesis.
Radial Flow reactor internals
In the typical configuration of a Radial Flow reactor, the reacting gas is conveyed radially on the catalytic bed through perforated plate distributors (scallops) located along the reactor walls or through the slots of an outer basket. After having passed through the catalyst bed, the gas is collected in a centerpipe and conveyed to the next reaction stage. There are also applications whereby the gas follows the same route in the opposite direction, in other words from the inside outwards, however the basic configuration of the internals is the same. As well as scallops and centerpipes, other internals normally present in Radial Flow reactors are: inlet distributors, deflecting baffles, centerpipe supports, coverplates, shrouds and catalyst transfer pipes. The main applications are: distribution of gas mixtures through catalytic beds and catalyst containment in the production of ammonia, in the extraction and treatment of gas and crude oil, in gas
isomerization and aromatization units and in catalyst reforming units. HUILONG is specialized in the construction of reactor internals; those most commonly used in the Radial Flow reactors are shown in the three
dimensional drawings that can be viewed by clicking on the respective names given to the right of the section plane. Moreover, starting from plates and wires made of stainless steel and special alloys, HUILONG manufactures wire meshes, perforated plates and wedge wire screens, which are the filtering elements most widely used in the construction of centerpipes, scallops and outer baskets.
Down Flow reactor internals
In a typical two-bed configuration of a Down Flow reactor, the reacting liquid is distributed, using an inlet diffuser, on the liquid distributor tray underneath. This tray has the function of evenly distributing the liquid on the catalyst bed underneath, supported by the catalyst support assembly. Moving down the reactor, we come to the quench zone where the reacting liquid is cooled through gas injection and is then conveyed into a mixing chamber. From here, the liquid is distributed onto the next catalyst bed thanks to a liquid redistributor tray. The outlet collector positioned on the bottom of the reactor, supports the lower catalyst bed and enables the reacted liquid to be conveyed outside. The main applications are: distribution and mixing of liquids and gases and catalyst support during hydrocracking, hydrotreating and isomerization processes as well as in the production of urea and methanol. HUILONG is specialized in the construction of reactor internals; those most commonly used in the Down Flow reactors are shown in the three
dimensional drawings that can be viewed by clicking on the respective names given to the right of the section plane. Moreover, starting from plates and wires made of stainless steel and special alloys, HUILONG manufactures wire meshes and wedge wire screens, which are the filtering elements most widely used in the construction of catalyst support grids and outlet collectors.
Other types of internals
This family of products includes some internal components similar, for their construction characteristics, to those previously mentioned but which cannot really be classified as reactor internals. Some examples are: edged wire cloth panels used in the polyester production process; special perforated trays for absorption and distillation columns; support grids for tube bundles and embossed plates for heat exchangers; support grids for molecular sieves; embossed and slotted trays used in copolymerisation processes.
