Catalytic reforming, hydro desulphurization, ammonia conversion, NOx removal, styrene dehydrogenation, solvent recovery and isomerization are typical processes using wedge wire screens.
Basically two type of reactors can be considered:
The radial flow reactor can again be divided into 2 types:
For both reactors the efficiency of the process depends on the screen internals. Trislot® wedge wire internals offer exceptional strength and resistance to collapse, breaking and buckling. The combination of high open area and non-clogging of the slots provides high volume flow and efficient media retention. Thanks to the vertical slots in the center pipe and the outer screen/scallops and the smooth surface, the catalyst beads can move up and down without being abraded or broken by the screens.
» Detailed description of the reactor internals
A down flow or up flow reactor uses flat screen to retain the treatment media or catalyst in its position and to foresee a collection place for the flow. Other internals used in this type of reactor are:
The efficiency of the process depends on the screen internals. Trislot® wedge wire internals offer exceptional strength and resistance to collapse, breaking and buckling. The combination of high open area and non-clogging of the slots provides high volume flow and efficient media retention. Many different alloys are available, even for demanding applications.
